We amused ourself with such a test on a forum. Someone used a wav to start, made an mp3 of it and brought it back to wav. Offered both tracks as wav without more info. See who can tell them apart. I agree it is very hard, and most (90%) won't be able to do it. You could do it with more types of music to check if it makes a difference. -- Havoc Havoc's Profile: http://forums.slimdevices.com/member.php?userid=5064 View this thread: http://forums.slimdevices.com/showthread.php?t=29286 ___ ripping mailing list ripping@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/ripping

I strongly doubt the CD version and HDCD version are mastered the same--in which case the FLACs for the two versions should sound markedly different. You've got to route everything through the same DAC and other hardware or it's not a valid test, sorry. Otherwise you can't say for certain the difference you're hearing isn't from the difference in quality between the two DACs, and not the compression at all. That's the breaks when you go the science route. All variables have to remain constant except the one you're examining. i.e. if one sample is resampled to 48KHz (ugh!), ALL samples have to be resampled to 48KHz.

I more value the time it takes to encode since my server/ripper sits on a very slow pc (but it doesn't use much current). This also means that every device could play the data back. The audio doesn't have to travel to other devices, so the format doesn't matter. I do have a lot of recordings that are saved as 24 and 32 bit wav files, so that would also be work saved. If I ever need to burn a cd from the files when a disc gets bad, it is less work again than having to transcode first. I don't feel 40% saving is worth the hassle compared to dropping in another disk. -- Havoc Havoc's Profile: http://forums.slimdevices.com/member.php?userid=5064 View this thread: http://forums.slimdevices.com/showthread.php?t=29286 ___ ripping mailing list ripping@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/ripping

Well my system doesn't compete with some of the stuff the 'Audiophiles' talk about but one thing is quite clear. Listening to a well recorded track from an MP3 and the sound comes out of the fireplace. Listen to the same track in Flac and the image comes from the whole wall. There really is no comparison.

Craig Not intending to throw any ice-water on this good discussion, but it's important to bear in mind that not all MP3s are created equal. I'm assuming for the purposes of THIS discussion we're talking only about MP3s ripped straight from the source CD using a good ripper, and encoded at the highest bitrate the MP3 format allows, preferably using LAME. I don't mean to pick on Craig, and that's not my intention, but I really do hear MP3s sound bad all the time. When in fact they mean MP3s created with iTunes at 128kbps sound bad, or some such thing. But we're not talking about low-bitrate MP3s created with sub-par encoders, we're talking about the best-quality MP3s possible with today's encoders. I've got problems with the MP3 format myself (I don't use it for anything I own), but at high enough bitrates, an MP3 will sound exactly the same as a CD for the vast majority of music, to all human listeners, period, and that's a statement which can be proven or disproven with an ABX test any time you like. Whether or not a format is transparent at a particular bitrate for a set of tracks for a particular listener isn't a matter of opinion or religion--you can test this yourself scientifically and get an answer. And if it's not double-blind, it's not a valid test. And yes, I'm the same person who posted the name of a sample which completely wrecks MP3 at 320kbps. My point was that killer samples are not representative samples, which is rather the point. -- CatBus CatBus's Profile: http://forums.slimdevices.com/member.php?userid=7461 View this thread: http://forums.slimdevices.com/showthread.php?t=29286 ___ ripping mailing list ripping@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/ripping

I have heard another killer track is -Kalifornia- by Fatboy Slim. The synthesized voice at the beginning of the track is quite problematic.

[SlimDevices: Ripping] Re: Audible difference between FLAC and 320 kps MP3s?
Once I did a comparison: I listened to a song with a folk-guitar and a violin as a 320Kbps mp3 and a wav-file. The difference was that the mp3 sounded much less transparent. Accoustic instruments generate many harmonics which make up the characteristic sound of each instrument. The high harmonics give the instrument a brilliance. These are very high frequencies, which are not completely reconstructed with any mp3-bitrate. If you use in the test electronic music or rock (etc.), you will probably not hear the difference between 320 and lossless. But with quality recordings of accoustic music, I think many people would hear the difference when listening on a good stereo. I guess it all comes down to your personal expectations, taste and priorities.

I also did a comparison between 320 kbps MP3 and the original, and was easily able to tell the difference. Then I did the exact same test double-blind, and suddenly my superhuman hearing abilities disappeared. Just saying...knowing which sample is which can do great things for your perception.

Unless you do an ABX yourself you won't know. Some people maybe able to hear a difference, others may not. I can't tell the difference myself. But you must ABX, just swapping tracks whilst knowing which format you're using is biasing the results.

Especially on my actual stereo--there's no comparison on any music. 320Kbps MP3 does sound really good, but FLAC always sounds better. I have a harder time telling on my work PC over computer speakers, but only between 320Kbps and FLAC. I can tell the difference between every other bitrate. Now, just because I can tell a difference doesn't mean I don't mind listening to lower bitrates, or that I don't enjoy them. It just means I can tell. Actually, I find MP3s of any bitrate annoying on my home system, but that's just because it's good enough to play back the bad stuff too. -- mrfantasy --Mike mrfantasy's Profile: http://forums.slimdevices.com/member.php?userid=1127 View this thread: http://forums.slimdevices.com/showthread.php?t=29286 ___ ripping mailing list ripping@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/ripping

I'd hate to give up the 40% or so of diskspace that Flac encoding saves me, with no loss of audio quality. The larger the library, the larger the savings in disk drive cost. And if you backup to disk, as I do, you need twice the drive space, so the savings can be considerable. The space savings can also be convenient. If I can fit my entire Flac library on a single moderately priced 400GB disk, and can fit the backup on a disk of the same size, then not having to use multiple drives, particularly for the backup, makes life much easier. -- JJZolx Jim JJZolx's Profile: http://forums.slimdevices.com/member.php?userid=10 View this thread: http://forums.slimdevices.com/showthread.php?t=29286 ___ ripping mailing list ripping@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/ripping

I think there is a meaningful savings in hard drive space. A typical FLAC file might be 30 MB, whereas the same song as a 320 MP3 is maybe 6 MB. That's a quarter of what the FLAC file is. I realize memory is getting cheaper all the time, but still . . . if you are achiving hundreds or thousands of songs, I think the space between the two is substantial. The other issue is encoding multiple times for various purposes. Right now I encode as FLAC for home listening on my main system, but if I want to grab an iPod and go, I need to recode as an MP3. It would be easier to just have one folder of songs that serve a variety of situations. An MP3 encoded with LAME at 320 kps would handle both scenarios -- it's just a question of whether the sound quality REALLY supports going lossless. -- alderash alderash's Profile: http://forums.slimdevices.com/member.php?userid=6784 View this thread: http://forums.slimdevices.com/showthread.php?t=29286 ___ ripping mailing list ripping@lists.slimdevices.com http://lists.slimdevices.com/lists/listinfo/ripping

It depends entirely on your system and your ears. There's no point whatsoever in asking someone else's opinion, as they will be listening with their system and their ears. From a scientific POV they are clearly and demonstratably different, but it all comes down to perception and sensitivity. Do the test yourself, if you can't tell the difference, then great, you can save a few gb. Whether that's worth it given the cost (in time) of reripping is quite another thing. I'm much more concerned about the amount of time it would take me to rerip to FLAC in the future than I am about using more disk space.
