[Bug 195483] Re: Sound Juicer - MP3 quality doesn't change
Does this bug still exist? The recent reviews (2013) for Sound Juicer complain about the poor quality. presumably because of this bug. (If bug it is. Having read all of the above I now cannot tell what it is.) On trying to decide on CD ripping software to produce MP3s to run under Xubuntu 13.04, I came across the Ubuntu help page on CD ripping ( https://help.ubuntu.com/community/CDRipping ) still has KennoVO's comment WARNING: the gstreamer LAME plugin, used in the instructions below, is broken and will produce substandard quality MP3s. You can track the bug here. If you want to create MP3s, it is recommended not to use Sound Juicer; use a program that doesn't interface with LAME through gstreamer instead. Good examples are RubyRipper and ABCDE. Is that still true? To get Xubutu 13.04's default ripping software, K3b, to produce MP3s, one must install LAME. How does one tell which CD ripping software doesn't interface with LAME through gstreamer? Asunder, Ripper X, Audex, AcidRip and RipOff are all highly rated in the Ubuntu Software Centre, but how to tell which are affected by this bug report? Any chance of a summary of what the state of this problem is? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/195483 Title: Sound Juicer - MP3 quality doesn't change To manage notifications about this bug go to: https://bugs.launchpad.net/gnome-media/+bug/195483/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

After further investigation with LiveCD sessions of Ubuntu 9.04, 9,10, 10.04 and 10.10 I can report that it's the introduction of Ubuntu's Software Center and its poor handling of essential dependencies etcetera that has sabotaged the addition of Ubuntu Restricted Extras and Sound Juicer (aka Audio CD Extractor) itself, and has also prevented the previously correct operation of the Synaptic package manager for the addition of other packages. This means that this Bug Report's discussions of profile modifications have been nugatory.

[Bug 195483] Re: Sound Juicer - MP3 quality doesn't change
You know an awful lot of nonsense gets dogmatically said on the topic of sound digitisation and this and other related Bug Reports have been no exception to that rule. Ignoring the inflammatory, not to say ignorant nature of some remarks, yet not yielding to rude bully-boy tactics, I will just make one last attempt to explain. CD audio digitisation of music is a compromise, originally derived from techniques used to digitise audio speech over buried copper wires, back around 1970. To then recode those results with MP3 inevitably imposes further limitations on the perceived quality, although 128K CBR coding is found acceptable by quite a lot of folk who have probably never heard anything better or who have already damaged hearing. More discriminating listeners, who may have experienced live orchestral music or old technology vinyl records and valve amplifiers or even modern products from the likes of NAIM (who haven't forgotten that it's user perception that counts) may be hoping for something better. CD-like Quality, provided that the reproduction equipment and listener perceptions are good enough, is generally recognised to be a better compromise for MP3 re-coding. On a 'please most of the folk most of the time' basis, 32-320K VBR coding seems to be acceptable, but most disagreement seems to have been about whether that new compromise is perfectly achieved, without stopping to simply listen to the results. When I simply stop to listen, 128K CBR sounds 'muffled' to my ears, whilst different VBR codings impose their own colouration, so it was with relief I found that Linux Sound Juicer could be modified for perceptibly better results, rather than using Windows hosted CDEX or later Foobar2000 as directly recommended by a Hydrogenaudio forum member. Using 'Bruce R' profiles I have received some very favourable comments from my circle of friends and others, including some musicians. However, the bottom line is that if they report an improvement using a 'KennoVO' profile, I may re-encode my CD collection for their listening benefit, but I hope to retain the freedom to make that choice, which is why I was distressed to have that apparently being desperately prevented, for whatever reason. -- Sound Juicer - MP3 quality doesn't change https://bugs.launchpad.net/bugs/195483 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 195483] Re: Sound Juicer - MP3 quality doesn't change
Some afterthoughts. In case it's not been clear, I am not interested in scoring 'brownie points' for 'being smart', only in obtaining a 'CD Quality' profile that consistently works for friends and other users, leaving 'B-cubed' to other folk, but so far I have not seen any meaningful definition of 'lame' versus 'lamemp3enc' terms and profiles, so if we are to be pedantic, I will in future just refer to the 'BruceR' versus 'KennoVO' profiles. Meanwhile, I see that the Ubuntu 10.10 'rc' releases are still exhibiting some inconsistencies in operation between the Ubuntu Software Center and Synaptic, in adding ubuntu-restricted-extras and sound-juicer, where initiation by the Software Center then needs completion or reinstallation by Synaptic. However, once installed, Audio CD Extractor's less obvious CD Quality, MP3 default profile is a KennoVO style profile (audio/x-raw-int,rate=44100,channels=2 ! lameemp3enc name=enc target=0 quality=6 ! xingmux ! id3v2mux) which I have simply amended with 'quality=2' before use in a LiveCD session. It's then a lot slower encoding than my 'Mint-9 on a stick' and still has 'a strident and raucous colouration' to my ears, but I really must get some younger, keener, and more musical ears to compare the results against the original CDs. -- Sound Juicer - MP3 quality doesn't change https://bugs.launchpad.net/bugs/195483 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 195483] Re: Sound Juicer - MP3 quality doesn't change
KennoVO - trying to respond in a less inflammatory style, your attached links made interesting reading, effectively discussing the absence of the settings used in my/other amended profiles for CD QualityMP3 before addressing the proposed use of xingmux, as then briefly revealed to the world in the Maverick Alpha2 development release. Please note that back in 2007, rather than using a 'down among the weeds' hex editor, I used EncSpot which rather uniquely produces histograms of resulting MP3s. Windows-hosted, sadly it's no longer supported although source code may still be available for its resurrection as a Linux tool. At the time, it confirmed that Sound Juicer defaults produced 128K CBR. Best advice was to use Windows CDEX with modified settings, effectively in a multi-pass operation to achieve 32K-320K VBR results as again confirmed by encSpot, but I found that by consulting gst-inspect lame, I could achieve similar results with Sound Juicer, as further confirmed by subjective tests. Since then there have been several reports of use of other tools and players, including VLC Player, that falsely report 32K-320K VBR encoded streams as 128K CBR, without folk simply listening to the difference, such is the blind trust in such tools, reinforced by a disbelief in faulty or limited software. This leads me to wonder what 'analysis' tools you guys have been using. Today, although there is the rather complex Linux mp3diags, I prefer to use the simple checkmp3 to report on encoded streams, plus actually listening to the results. However, with my recently restored vision I have searched for and found my original test CD, a Deutsche Grammophon recording of the Planet Suite. Also, although several PC failures have lost other information, I still have a working copy of EncSpot, so I have just run tests on three differently-created copies of the Jupiter sound track I attach a text file of checksum results, plus four EncSpot JPEG image files. ** Attachment added: checkmp3 text plus four image files https://bugs.launchpad.net/ubuntu/+source/sound-juicer/+bug/195483/+attachment/1647589/+files/Maverick%20Alpha2%20Histogram.jpg -- Sound Juicer - MP3 quality doesn't change https://bugs.launchpad.net/bugs/195483 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Ok, now these opinions about differences between results or different testing tools are silmply useless. Here we are searching for the cause of the bug and for the best solution to it. The cause was a buggy/misused gstramer plugin lame. Now developers rolled out lamemp3enc, a better interface to the same library. All we need is that the sound-juicer Gstreamer pipeline is changed to use it. So, which are the best default options? I don't know.

[Bug 195483] Re: Sound Juicer - MP3 quality doesn't change
Long ago, when my hearing was a lot keener, Xing encoding in AudioCatalyst markedly improved upon Frauhofer encoding in AudioGrabber and was faster, so using a new implementation of what was a non-free product in Sound Juicer may provide a better result. I am puzzled at Ubuntu's discarding it after Maverick Alpha2 and assume that it will be re-instated or simply discarded for the 10-Oct-2010 release. Meanwhile, despite refutation that has included false accusations of results remaining 128K CBR rather than 32-320K VBR, the settings used by me have simply worked well, whilst Maverick Alpha2 settings are fine but a little strident to my old ears. When someone 'comes clean' about Maverick intentions, I will try out some subjective comparison tests on younger, keener hearing ears. It would be nice to think that there are no other questions, but I'm not yet convinced that it's actually broken, only mis-used, although that doesn't fit well with Canonical policy 'to fix what ain't broke'. -- Sound Juicer - MP3 quality doesn't change https://bugs.launchpad.net/bugs/195483 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 195483] Re: Sound Juicer - MP3 quality doesn't change
- This is not about bit rate, this is about quality. Getting a higher bit rate does not automatically equal getting a higher quality. In fact, botching the psychoacoustics model with a load of settings is a good recipe to get similar or higher bit rates but a lower quality. - For assessing quality, one person's subjective listening tests mean next to nothing. It is for this reason that I kept my own perception of sound quality out of this discussion (I also have a set of pretty good headphones and trained ears, but that's simply not relevant). However, there are ways to objectively test quality, by using ABX methodology, long systematic testing, a large sample of listeners, and sounds statistical analysis. That 's exactly what the folks at hydrogenaudio.org did, and they came up with recommended settings for standalone LAME. They also found that it's easy to pull down the quality by giving LAME a bunch of extra switches (you'd have to go digging through the hydrogenaudio forums for that). For this reason, I will trust anything that gives output that is bitwise identical to standalone LAME with the hydrogenaudio recommended switches, and I will not trust anything else. The lamemp3enc element falls into the former category, the lame element into the latter. Histograms of bitrates are irrelevant. - Conicidentally, the same people at hydrogenaudio.org found that Nowadays LAME is considered the best MP3 encoder at mid-high bitrates and features the best VBR model among MP3 implementations. Oh, and there's what they think about Xing: The Xing (pronounced zing) MP3 encoder was one of the fastest MP3 encoders. Of course that comes with a price, and quality wasn't on par with encoders tuned for quality instead of speed, like FhG Slowenc (Audioactive) and LAME. So here we are, LAME is at the very least one of the best encoders out there, and nobody will miss the restricted ones that were thrown out. As FiloSottile said, the lame interface to liblame is buggy, the lamemp3enc interface is not. The only thing up for discussion is really how to call lamemp3enc (and make sure it's implemented in the Maverick release).

You know, I can remember the same sort of sweeping, dismissive statements being made when CDaudio sampling rates, A-D quantization and coding laws were discussed, with audiophiles being disappointed that a higher sampling rate, number of levels or a better coding law were not chosen. At the time those with deep pockets could demonstrate the superiority of vinyl's better dynamic range, rather ignoring record tracking distortion, so what emerged was a compromise. The further stage of then re-encoding that to MPEG1 Layer 3 standards with various proprietary or free tools seems to be going through a similar set of arguments. As to 'statistically significant' blind tests they often forget to take account of the different human beings involved and their specific musical preferences. If you merely look at high frequency perception this is permanently damaged by exposure to intense high frequencies, in my case compressor 'whistle' or jet engine 'whine' that reduced my teens 24kHz hearing to 17KHz in my thirties and is now barely 15kHz, despite taking care. That still doesn't stop folk with more severely damaged hearing from spending vast sums on hi-quality reproduction kit or arguing for 'more faithful' coding, but that's life. In practice I have found that it's a good idea to include some young folk with undamaged hearing when sorting out the best, within budget compromise. As it's only a few weeks away, I'll wait to seen what Maverick finally chooses before conducting further coding and subjective tests with actual equipment and consumers.

In an ideal world, gnome-media should adopt it, then Ubuntu should simply pull it in from the upstream repo's. However, there's no time for that anymore; the gnome-media people haven't even looked at my new bug report yet, leave alone discussed it and committed it, and Maverick comes out of beta and into release candidate in 2 days, at which point they won't be willing to change a lot anymore, leave alone pulling in new stuff from upstream.

[Bug 195483] Re: Sound Juicer - MP3 quality doesn't change
Upon reflection I think I see where your confusion arises, KennoVO. Although the GStreamer lamemp3enc is what is invoked by the default and by modified profiles, it still needs instructing using original lame commands, which is why, if you want to try different settings, you need to have the 'gst-inspect lame' listed commands, which is what I reproduced as a PDF file. 'gst-inspect lamemp3enc' merely produces some less helpful information about its status. I would also add that I am not an obsessed with perfection/detail kind of a guy, having found that in a long career as a professional engineer, documentation, like the software itself is rarely perfect and it's best to just use 'what works', whilst leaving others to eventually come up with a better mousetrap and instruction manual. (By way of example, in the case of GRUB2 or even PulseAudio it will probably be a long time, if ever, before that occurs.) -- Sound Juicer - MP3 quality doesn't change https://bugs.launchpad.net/bugs/195483 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 195483] Re: Sound Juicer - MP3 quality doesn't change
BruceR, the things you're saying are simply not true. This is complex business and I can understand it confuses you, but please don't make stuff up. Browse Gnome Bugzilla (links at the end of this post). Look at the source code. Encode the same sample with gstreamer and with standalone LAME and do a binary comparison on the outputs (a hex editor might be helpful for this purpose). What you need to understand is that the deprecated lame element and the new lamemp3enc element are simply two different gstreamer interfaces to the same liblame library. The lame element is called by specifying lame in the gstreamer pipeline, the lamemp3enc element is called by specifying lamemp3enc in the gstreamer pipeline. Not difficult so far. Now, here are the differences: - The lame element tried to expose each and every LAME flag to the user, including many developmental flags that were never meant by the LAME developers to be set by end-users. Unfortunately, it had default values for each and every of these flags, and it would pass all of them on to liblame. This was harmful because (1) not all of the lame element's default values were sensible and (2) these flags override a number of settings that otherwise would be set internally by liblame at runtime depending on the situation. - Specifically to cure this problem, Sebastian Dröge wrote the lamemp3enc element, at the request of (among others) Gabriel Bouvigne (LAME developer), David Joaquim (gnac developer) and myself. The lamemp3enc element is a much simpler interface, giving the user only the few options that were meant by the LAME developers to be set by end-users. Flags that are not specified by the user (in the gstreamer pipeline) are mostly left undefined, allowing liblame to achieve its maximum quality by setting the corresponding settings internally to sensible values depending on the situation. If you don't believe me, here's some background information.

[Bug 195483] Re: Sound Juicer - MP3 quality doesn't change
It's taken over a year for me to obtain a cataract operation, but I can now see well enough to add another response to this Sound-Juicer problem saga. When I first researched modifying Sound Juicer (aka Audio CD Extractor) back in LinuxMint-4 and Ubuntu 7.10 days, I downloaded and printed out the 'buntu-restricted-extras, gst-inspect information for the included LAME encoder variant (aka lamemp3enc). However, I was then greatly aided in data interpretation by a Windows audio expert (aka Slipstreem), who knew all about LAME developer activities and guided my work and use of no-longer-available graphical EncSpot to assess the outcome of applied modifications. Only being interested in 'CD Quality MP3' that by default was actually only Constant Bit Rate (CBR) 128K, I wasn't interested in greater than 320K studio quality but in 32K-320K Variable Bit Rate (VBR) quality. Since then, folk have failed or been unable to add the requisite 'ugly' plugins that are part of the 'buntu-restricted-extras suite, which hasn't been helped by release varying Synaptic 'glitches'. Also, in typical typo-intolerant fashion, folk have failed to enter the profile modifications that I recommended. To recap, after Adding 'buntu-restricted-extras and then Sound Juicer, select Edit Preferences, select the requisite CD Drive, select Eject after extracting tracks and Open music folder when finished. Next select 'CD Quality, MP3 (.mp3 type)' Output Format and Edit Profiles, then select 'CD Quality, MP3' and Edit. Finally Edit the Gstreamer pipeline as follows and then Close, Close, Close to save all modifications, which become the defaults. Initial, default profile : audio/x-raw-int,rate=44100,channels=2 ! lame name=enc mode=0 vbr-quality=6 ! Id3v2mux Amend mode=0 to mode=1, to obtain 'Joint Stereo' Amend vbr-quality=6 to vbr-quality=2, for the benefit of young and keen of hearing Insert vbr=4 to employ LAME's new VBR algorithm (nothing to do with misquoted quality) Insert vbr-min-bitrate=32, to set the minimum VBR bitrate Insert vbr-max-bitrate=320, to set the maximum VBR bitrate Hence the final, modified profile : audio/x-raw-int,rate=44100,channels=2 ! lame name=enc mode=1 vbr=4 vbr-min-bitrate=32 vbr-max-bitrate=320 vbr-quality=2 ! Id3v2mux (KennoVO - note that 'lame name=enc' ensures use of the correct LAME plugin.) In general, note that distributions like LinuxMint-9 'dvds' and PCLinuxOS have got round all the plugin addition problems by pre- including them. Meanwhile, Ubuntu 10.10 Alpha2 briefly introduced a new default as follows, but it's been abandoned in later development releases, so who knows what the formal release will use : audio/x-raw-int,rate=44100,channels=2 ! lamemp3enc name=enc target=0 quality=6 ! xingmux ! Id3v2mux I don't claim to have achieved perfection with my modifications, but most if not all listeners are content with achieved playback through reasonable equipment.

[Bug 195483] Re: Sound Juicer - MP3 quality doesn't change
Bruce R, please read all the posts carefully. The lame element is known to be broken, and has been superseded by lamemp3enc. Stop encouraging people to use the lame element. https://bugzilla.gnome.org/show_bug.cgi?id=494528 (FYI, Gabriel Bouvigne is one of the core LAME developers). I did elaborate tests and not even once succeeded to make the lame element produce the same output as the standalone LAME program, because the lame element internally sets a whole series of developmental LAME flags to ill-conceived values. Ironically, the combination of flags you're suggesting are the ones I came up with in January 2009: https://bugs.launchpad.net/ubuntu/+source/sound-juicer/+bug/195483/comments/22 Notice the last two sentences of my post. Yes, these flags seem to be well behaved if you only look at the output bitrates, but remember, bitrates are not everything. It's perfectly possible to encode at high bitrates and still have audible artifacts *cough* xingmp3encoder *cough* Again, the lame element is officially deprecated; the lamemp3enc element leaves all flags at their (good) default values and produces outputs that are bitwise identical to standalone LAME. Oh yeah, I still don't know what name=enc does, but it's definitely *not* ensuring use of the correct LAME plugin. My best guess so far is that it sets some tag, which perhaps facilitates interfacing with some other program. -- Sound Juicer - MP3 quality doesn't change https://bugs.launchpad.net/bugs/195483 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 195483] Re: Sound Juicer - MP3 quality doesn't change
KennonVO - I think that you will find that my settings do in fact use the GStreamer lamemp3enc and NOT what you call 'broken lame', which can still be installed and used or mis-used by other ripping tools, yet which I have not recommended as misquoted by you, whilst the xing encoder is yet another animal that I have used in the past, post fraunhofer and it's not too bad. Incidentally, in view of misleading reporting by tools and even players like VLC, simple checkmp3 does a better job of analysing mp3 files, but you may prefer trying mp3diags now that Win EncSpot isn't readily available. At the end of the day, subjective assessment by those with keen hearing using decent reproduction kit, like Sennheiser 'phones is probably the best arbiter as to what's acceptable CD-like quality.

[Bug 195483] Re: Sound Juicer - MP3 quality doesn't change
OK, this might be getting confusing. Just a summary for people who are new to this bug, and some suggestions for future directions: - People initially filed this as a sound-juicer bug, while *at that time*, it was actually a gstreamer bug; the lame element, which was responsible for encoding mp3 files by interfacing with the LAME mp3 library, was misbehaving. - Rather than attempting to fix the lame element, which was entirely based on incorrect assumptions, Sebastian Dröge created a brand new LAME interface named lamemp3enc, which is simple to use and in line with the LAME developer's UI guidelines. http://lame.sourceforge.net/lame_ui_example.php Around that time, I stopped following this bug, assuming that it would be fixed soon (I'm using RubyRipper with standalone lame for my own CD ripping purposes so I'm not directly affected). - Now, more than a year later, lamemp3enc is indeed in gstreamer0.10-plugins-ugly-multiverse (which is good), but sound juicer still calls the obsolete and buggy lame element instead of lamemp3enc (which is inane). - So, what we're looking at *right now* is a sound juicer bug (yes I consider a default setting that results in data loss - quality loss actually - a bug), and what we need is suggestions for default gstreamer pipe lines for sound-juicer. - A good starting point for this would be hydrogeaudio.org - the guys over there are digital audio professionals and enthusiasts and they have done an incredible amount of ABX blind testing and debating to come up with recommendations for using lame. http://wiki.hydrogenaudio.org/index.php?title=LAME * For what most people would call CD quality, they recommend VBR qualities 0,1,2 or 3 (according to taste). * For portable mp3 player quality, they recommend VBR qualities 4, 5 or 6 * For voice quality they recommend ABR with a target bitrate lower than 100. The current juicer presets join the channels to mono when voice is selected, so in that case, a target bit rate of 56 seems sensible (ie. lamemp3enc name=enc target=1 bitrate=56 mono=true , thus mimicking --preset voice of standalone lame). - How to implement this all depend on how much of these internals one would want to expose to the user. While I myself would very much enjoy juicer giving me the option to choose between VBR and ABR and set the quality/bitrate myself (as FiloSottile seems to suggest), juicer's design philosophy seem to be to keep it simple and stupid. In that case picking one CD quality preset, one portable mp3 player preset, and one voice preset would be the way to go. - Finally, the sound juicer devs (or whoever makes up these defaults) seem to be biased towards lower bitrates/qualities; the current CD quality preset attempts to use VBR quality 6, in which most people could clearly hear the artifacts giving good enough listening conditions. - Anyway, to stay totally in line with juicer's design philosophy (however objectionable this may be), my final recommendation would be to use FiloSottile's audio/x-raw-int,rate=44100,channels=2 ! ... ! xingmux ! id3v2mux with the following lamemp3enc lines: CD quality: lamemp3enc name=enc target=0 quality=2 portable mp3 player quality: lamemp3enc name=enc target=0 quality=6 voice quality: lamemp3enc name=enc target=1 bitrate=56 mono=true PS: I don't know why it would be needed to specify name=enc but it won't hurt and a lot of people are doing it, so it might be good for something. -- Sound Juicer - MP3 quality doesn't change https://bugs.launchpad.net/bugs/195483 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Wow, just updating from a LiveDVD session of Maverick Alpha3 to let folk know that, after adding sound-juicer and ubuntu-restricted-extras, 'Audio CD Extractor', aka Sound Juicer's default Quality MP3 profile is now audio/x-raw-int,rate=44100,channels=2 ! lamemp3enc name=enc target=0 quality=6 ! xingmux ! id3v2mux, which then defaults to creation of 32K-320K VBR instead of 128K CBR MP3s.

Sorry to be slow to add this comment folks, but it looks as if my original Sound Juicer recommendations haven't been strictly followed, the most common mistake being to insert 'vbr=3' instead of just 'vbr=4' in editing the profile, which de-selects LAME's new VBR algorithm instead of selecting it. The next most common mistake appears to be not installing the associated GStreamer LAME plugin by installing 'ubuntu-restricted-extras', which sadly gets stalled in installing MScoreTTFonts for some variants of Ubuntu.

[Bug 195483] Re: Sound Juicer - MP3 quality doesn't change
It's nice to be able to offer a solution for a change. The fault lies not with GStreamer, but with a failure to provide the wrong command string or 'profile' for LAME to execute. For the CD Quality MP3 Profile, Edit it to read as follows : audio/x-raw-int,rate=44100,channels=2 ! lame name=enc mode=1 vbr=4 vbr-min-bitrate=32 vbr-max-bitrate=320 vbr-quality=3 ! id3v2mux This will result in what I call 'Super MP3' quality, average 171Kbps, ranging from 32-320Kbps, in accordance with another forum audio expert's recommendations, back when I researched sound-juicer as a suitable Linux ripping tool, which was around the time of Ubuntu 7.10 and LinuxMint-4. As I recall, the mode=1 entry ensures stereo channel separation, the vbr=4 entry ensures correct operation with the old version of LAME then being used, the critical vbr-min and vbr-max commands set the range of compression desired and the quality command merely adds a subtle enhancement, Note that this also works with other distros, especially PCLinuxOS. Regarding Scott Bronson's comment, by also setting Preferences to Eject after extracting and Open music folder and running it while using a fast Internet connection for automatic tracks data download, it can be a quite fast process of just putting a CD into the preferences optical drive, clicking on Extract and waiting for the disc to be ejected. -- Sound Juicer - MP3 quality doesn't change https://bugs.launchpad.net/bugs/195483 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

The Ubuntu project is far too casual about this data loss bug!

A computer should never lie to the user about what's happening. (I just ripped a 15 CDs on Karmic using the default CD Quality MP3 setting and only discovered this bug by chance.

[Bug 195483] Re: Sound Juicer - MP3 quality doesn't change
@Christian Niemeyer: I believe vbr-mean-bitrate actually requests ABR encoding, which conflicts with vbr-quality=4, the switch that requests VBR encoding. @tigerdog: Nyquist's theorem dictates that the lowpass frequency needs to be significantly lower than half of the bitrate (44100) to avoid aliasing artefacts (which can be quite severe). I believe standalone Lame internally sets the lowpass to 21000 when asked for CBR 320 (the highest quality available), to 19500 when given -V 0 (the highest VBR quality), and even lower for lower qualities. Anything higher than 21000 is considered unsafe with regard to aliasing. @everyone: knowing just how many internal switches LAME has and how unskillfully the defaults are set in the gstreamer plugin, it is very unlikely to find a gstreamer command line that works as intended and will pass rigorous listening tests. The issues with the above command- lines perfectly illustrate my point. The only way to fix the problem is at code level, and posting command-lines will just distract from this. -- Sound Juicer - MP3 quality doesn't change https://bugs.launchpad.net/bugs/195483 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 195483] Re: Sound Juicer - MP3 quality doesn't change
It seems the only way to get gstreamer to work the way you want is to override
every one of its settings with something you want. I was finally able to use
this pipeline:
audio/x-raw-int,rate=44100,channels=2 ! lame name=enc mode=0 vbr=4
vbr-quality=0 quality=0 vbr-min-bitrate=32 vbr-max-bitrate=320
lowpass-freq=25000 ath-lower=0 ! id3v2mux
to get insane-quality VBR files equivalent to
lame -m stereo -q 0 --vbr-new -V0 --add-id3v2 {infile} {outfile}
I used VLC's statistics feature as suggested above and found these files
to have the same stream bitrate and variability with files created by
command-line invocation of LAME using the above parameters.
gstreamer definitely needs some way of invoking LAME with only the
overrides provided in the pipeline instead of specifiying its own
(difficult to decypher) defaults.

The weird thing is, when you check those vbr mp3s created with sound- juicer in VLC (Ctrl+i there the statistics-tab) the vbr-bitrate only varies around 10 kb/s or even less, up and down. Check at the Input box the values for Input bitrate and Stream bitrate. This is technically VBR, but not the way VBR is intended. Imho, VBR does have a wide range of bitrate. So the VBR encoding remains somehow useless with sound juicer. I think this happens since gstreamer-0.10.

[Bug 195483] Re: Sound Juicer - MP3 quality doesn't change
@KennoVo: I tried half a day yesterday trying to get different VBR- mp3-filesizes and came to the same conclusion. Thanks for explaining. For example I tried this: audio/x-raw-int,rate=44100,channels=2 ! lame name=enc mode=0 quality=2 vbr=4 vbr-quality=3 ! xingmux ! id3v2mux then checking with VLC's Stream and Media Info... (Ctrl+I) the bitrates and it was just switching aroung 158kbps to 162 kbps. No matter if vbr-quality was 0 or e.g. 4. This is because of the too much default values gstreamer passes to lame, like vbr-min-bitrate, vbr-mean-bitrate and vbr-max-bitrate. Usually with vbr-quality you choose kind of a preset for bitrate measure. Like when using lame on the command line. quality is just how good the general algorithm for encoding is. Even bitrate (for CBR useful) always (!) passes a default value. This is so confusing. ;-) I tried many gstreamer pipelines with the same song (length 4:19) and always got 4.9 MB or 7.3 MB, no matter how detailed and different my settings were. Though encoding as VBR worked and Rhythmbox and Nautilus getting the lenght right, which is an improvement though. With this pipeline: audio/x-raw-int,rate=44100,channels=2 ! lame name=enc mode=0 quality=2 vbr=4 vbr-quality=3 ! xingmux ! id3v2mux I managed to get a filesize of 5.5 MB, which is kind of quality vs. filesize, that I was looking for. Though I'm confused how fast gstreamer is with encoding, but maybe that's because of the pipeline. Grip is much slower. Now I'm wondering if this has any quality issues maybe. Again the Defaul values you see by gstreamer-inspect lame are altogether too much and very counterproductive for the result. Someone knowing if there is a possibility to switch this default values to none or not set? This would be a good workaround. Last question: When will gstreamer-0.11 will be released? Google doesn't help me with that question. PS: Set Importance at least to medium. Though this is a universe/multiverse bug, it is a showstopper for people who want VBR mp3s.

[Bug 195483] Re: Sound Juicer - MP3 quality doesn't change
Things are actually worse than they seem. As a matter of fact, LAME should only be invoked with a handful of simple master options (like -V4), each of which activates myriads of internal encoder parameters. Manually setting those parameters through advanced switches will disrupt the carefully tuned balance between the different encoder parameters, and result in substandard MP3 files. See the LAME man pages and also http://wiki.hydrogenaudio.org/index.php?title=LAME Now, the problem is, the gstreamer LAME plugin implements an large number of these advanced switches, and sets them all to a default value, thereby completely overriding LAME's normal mode of operation. A list of these options can be obtained by typing: gst-inspect-0.10 lame The developers of gst-plugins-ugly are even aware of this, judging by the gstlame.c source code, which is ridden with comments like this: /* FIXME 0.11: Remove all properties except the useful ones. Nobody knows what most * properties are doing and they're intended for LAME developers only. */ As a demonstration, I tried to find a combination of gstreamer lame settings that reproduce the behavior of invoking standalone LAME. After half a day of trying, I gave up. Conclusion: gstlame.c is broken. If you want to rip CDs to mp3 format on UBUNTU, use rubyripper instead of juicer http://wiki.hydrogenaudio.org/index.php?title=Rubyripper#Installation_on_Ubuntu_8.04 For the die-hards that absolutely insist on using the gstreamer LAME plugin, please be aware that the workarounds in earlier posts in this thread are flawed. Most importantly, by setting vbr-max-bitrate=256 to values lower than 320, they disregard the following recommendation from the LAME man page: The use of -B is NOT RECOMMENDED. A 128 kbps CBR bitstream, because of the bit reservoir, can actually have frames which use as many bits as a 320 kbps frame. VBR modes minimize the use of the bit reservoir, and thus need to allow 320 kbps frames to get the same flexibility as CBR streams. The best combinations of flags I could come up with in my abovementioned experiment were: If your most important goal is to minimize the risk of audible MP3 artefacts: lame name=enc mode=0 vbr=4 vbr-min-bitrate=32 vbr-max-bitrate=320 vbr-quality=0 A good trade-off between file size and quality: lame name=enc mode=1 vbr=4 vbr-min-bitrate=32 vbr-max-bitrate=320 vbr-quality=4 Note that I don't really recommend using these settings, as they don't do LAME any justice.

To verify that VBR is actually working after you have encoded your files you will need to use a media player that will report back to you real time statistics about what is happening during decoding.

Look here: http://ubuntuforums.org/showthread.php?t=608034highlight=vbr+mp3 Several of us are getting low quality cbr's no matter what we do with sound juicer. Jorns, however, replied that it worked just fine for him and he was able to get genuine vbr files. He writes: -- jorns to me show details Mar 23 (13 days ago) Reply I tried the above mentioned sentence: audio/x-raw-int,rate=44100,channels=2 ! lame name=enc mode=0 vbr=4 vbr- quality=0 vbr-min-bitrate=160 vbr-max-bitrate=192 ! xingmux ! id3v2mux and changed 192 with 256. For me it worked like a charm, it now makes VBR mp3's between 160-256 kbps. My software is the same, Ubuntu 7.10 and Sound Juicer 2.20.1 - So what makes the difference here?

Re: [Bug 195483] Re: Sound Juicer - MP3 quality doesn't change
I tried it, except I changed vbr-max-bitrate=192 to vbr-max-bitrate=256. The cd ripped just fine, but Amarok reports a bitrate of 128 for all the tracks. This is something that's definitley broken in g-streamer as is well documented in the ubuntu forums, it's definitly not fixed, I don't know how to fix it, and the bug guys just don't seem interested. This is very peculiar since variable bit rate encoding of mp3's is such an important function. Note that Amazon.com (which incidentally has recently released a linux version of it's downloader) encodes all it's DRM-free tracks with vbr avg bitrate 256. Did you check to see what bitrates your software is reporting for the cd's you ripped?

Thank you for taking the time to report this bug and helping to make Ubuntu better. The issue that you reported is one that should be reproducible with the live environment of the Desktop CD of the development release - Hardy Heron. It would help us greatly if you could test with it so we can work on getting it fixed in the next release of Ubuntu.
