CU nils if it isn't mp3, it kind of limits what one can do... =( sure there may be a player, or plug_ins for some players but you lose the freedom that exists in mp3 being a "standard". for me it would mean that i couldn't use them in my empeg, heh. besides, i got like 70gb+ of mp3s right now. don't want to reencode things until i have to (converting everything to vbr is taking me long enough). steve Seems to me a bad reason. You don't need to reencode your files, keep under mp3 what is already mp3, and just use new formats for future encodings, if you think that new formats are better. The point here is that mp3 is a proprietary format, while ogg is an open one. Moreover ogg have several interesting features: for example it is natively VBR, while mp3 is basically CBR: VBR is not nicely implemented in mp3. Related question: wouldn't the experience accumulated in the Lame project be useful for the ogg project (GPSYCHO,...) ? Couldn't Lame and ogg cooperate ?

Related question: wouldn't the experience accumulated in the Lame project be useful for the ogg project (GPSYCHO,...) ? Couldn't Lame and ogg cooperate ? they already do. we all work for the same company, and for the same goals. icecast, ogg, lame, and some other stuff are all part of the same force to get a consistent and open media framework that everyone can openly and freely use and develop with. jack. -- MP3 ENCODER mailing list ( http://geek.rcc.se/mp3encoder/ )
[MP3 ENCODER] where to find newest linux Lame binaries?
Hello All, I'm looking for a page as great as Dmitry Kutsanov's is for win32 binaries, but with recent compiled Linux binaries. Anyone? thanks? Also they (.r3mix.net visitors) asked me if the Lame is linux-multithreaded? I'm guessing not since there is only 1 important consecutive encoding process? thanks r3mix.net -- MP3 ENCODER mailing list ( http://geek.rcc.se/mp3encoder/ )
Re: [MP3 ENCODER] default high pass filtering

This could be bassNN_N.wav from SQAM (at low bitrates). about anything from "Grotus" as well (_very_ fat bass) On some signals, however, highpass filters can do bad things as well. For example, after processing this file http://www.geocities.com/SiliconValley/Bit/5683/test1c.zip with a 5 Hz highpass filter, the peak amplitude increased to about 52000, resulting in lots of clipped samples. -- MP3 ENCODER mailing list ( http://geek.rcc.se/mp3encoder/ )

Re: [MP3 ENCODER] free format bitstreams and iso documentation
According to my ISO doc (section 2.4.2.3), for layer III, decoders are not required to support higher free format higher than 320kbps. So free format is not restricted to =320kbps. And decoders must support free format at least up to 320k. My ISO 13818-3 documentation : Section 2.4.2.3 "The decoder is not required to support bitrates higher than 256 kbit/s, 160 kbit/s, 160 kbit/s in respect to Layer I, II and III when in free format mode." And in 2.1.74 : "2.1.74 free format [audio]: Any bitrate other than the defined bitrates that is less than the maximum valid bitrate for each layer." You're reading the mpeg-2 doc. That's why you get lower limits. But your doc only indicates the maximum bitrate that decoders are required to support, and does not mention a limit for encoders.

Re: [MP3 ENCODER] free format bitstreams and iso documentation
[...] As Gaby pointed out, it says the "decoder is not requires to support..." which doesnt say they are invalid MP3 files :-) Hey, btw, I just tested free-format with mpega.library and AmigaAMP's internal decoder (FhG licensed), and both failed miserably. :/ - CISC -- MP3 ENCODER mailing list ( http://geek.rcc.se/mp3encoder/ )
Re: [MP3 ENCODER] MPEG2
Hi, Excuse me, I must be missing something really obvious.. I see that lame supports MPEG 2 and 2.5, but how do I create an MPEG 2 or 2.5 file with lame? I don't see a switch for it.. Is it enabled automatically for some kinds of audio? Regular MP3s are Just MPEG 1, right? MPEG1, 2 and 2.5 is determined by the output samplerate; MPEG1 layer III samplerates(kHz): 32 44.1 48 bitrates(kbs): 32 40 48 56 64 80 96 112 128 160 192 224 256 320 MPEG2 layer III samplerates(kHz): 16 22.05 24 bitrates(kbs): 8 16 24 32 40 48 56 64 80 96 112 128 144 160 MPEG2.5 layer III samplerates(kHz): 8 11.025 12 bitrates(kbs): 8 16 24 32 40 48 56 64 80 96 112 128 144 160 so to make an MPEG2 file, use, for example, "lame --resample 24" -- MP3 ENCODER mailing list ( http://geek.rcc.se/mp3encoder/ )
