Re: [MP3 ENCODER] CSV source code
Hi rename all the extensions from "h,v" "c,v" etc. to "h" "c" and so on. Remove ",v" from all file extensions and try again. In DOS/Windows command line, type: ren *.h_v *.h ren *.c_v *.c and so on. Cheers Jason Antony 27 30.874' S, 153 02.814' E These ",v" extensions are part of CVS. I didn't realize this, but from this thread I gather that the .tar file that you can download from sourceforge.net is not the LAME source code, but an archive of the LAME CVS repository. CVS is "Version Control Software" (www.cyclic..com). It lets multiple developers all work on the same source code at the same time, and keeps track of all the revisions. The best way to work with those ",v" files is to install winCVS and then have CVS to "checkout" the lame source code. But if you go through the trouble to install winCVS, then you can also checkout the lame source code directly from the sourceforge.net repository. see: the cvs and win32/cvs howto's on http://sfdocs.sourceforge.net/sfdocs/ (for anonymous CVS access (read-only) you dont need to install ssh) Mark -- MP3 ENCODER mailing list ( http://geek.rcc.se/mp3encoder/ )
Re: [MP3 ENCODER] mp3enc 3.1 and -l3wav (putting an mp3 inside a wav)
"Ampex" wrote- Is there a program that can do this externally of an encoder? Ie: take an mp3 and wrap it into a wav? CDex can do it. It also does ripping/encoding, but I found that adding the WAV header only works correctly with CDex if you do it separate to the encoding. The latest version may be fixed.

[MP3 ENCODER] free format bitstreams
Hi, All! Under windows, the results are the following: Winamp 2.6, new in-mpg123 for winamp, Nad 0.93, Sonique 1.51, AudioActive 1.93b, K-Jofol 0.6, Digideck 0.82, Winplay3 2.3, ActiveMovie/MediaPlayer 6.4, Xing MPEG player : all failed (quite disappointing) RH Beside freeamp for Win9x here is another Player called Pulse RH that supports free format MP3s: RH http://www.dspaudio.com RH It can handle a lot of file formats. Its MP3 decoder is based on Xing RH routines, just like freeamp. DSS(latest version) from http://www.chat.ru/~lrsp also supports Free Format bitstreams. Just now only up to ~440kbps ;) , but on my HDD exist version, that support up to 8kbyte/frame bitstreams. ;-) It will be uploaded as soon as possible. WBR, Sergey.

Re: [MP3 ENCODER] mp3enc 3.1 and -l3wav (putting an mp3 inside a wav)
I doubt you want to hear this, but this should be a pretty easy program to write yourself. The hardest part would probably be finding a copy of the RIFF WAV spec (a Microsoft/IBM standard which is, of course, available at neither of their web sites), and then finding the details of specifying an MP3 encoded chunk, which is a relatively recent addition to the spec. After that, it's pretty much just a matter of generating a few 'chunks' of header info and patching them onto the MP3 data. If you're interested, but can't find the spec out there, email me, and I'll see if I can dig up my copy. Details can be found here : www.wotsit.org Perhaps a -l3wav option could be added to Lame?

Re: [MP3 ENCODER] --cwlimit option
What really does the cwlimit option do/change? That is one thing I am clueless on. -- LAME uses a formula (from the ISO docs) to estimate the tonality of each frequency band. It computes this up to N khz, where N is specified by "--cwlimit N" (default=9khz). Above 9khz, a default tonality value is used. The tonality is used for the spreading function. The more noiselike a signal, the more masking it generates. Mark -- MP3 ENCODER mailing list ( http://geek.rcc.se/mp3encoder/ )

Re: [MP3 ENCODER] l3psycho_anal
The decision to encode in M/S or Stereo could be made in
l3psycho_anal, just after it determines the block type,
but this would make the routine even bigger :-)

In the big (too big?) l3psycho_anal function, in the "determin final block

is there something like blocktype[chn] to know it?

Hi Gabriel,
the decision to encode in M/S or Stereo is made in lame.c:

check_ms_stereo =

}
if (check_ms_stereo) {
/* ms_ratio = is like the ratio of side_energy/total_energy */
FLOAT8 ms_ratio_ave;
/* ms_ratio_ave = .5*(ms_ratio[0] + ms_ratio[1]);*/
ms_ratio_ave = .25*(gfc-ms_ratio[0] + gfc-ms_ratio[1]+
ms_ratio_prev + ms_ratio_next);
if ( (ms_ratio_ave .35) (.5*(gfc-ms_ratio[0]+gfc-ms_ratio[1]).45) )
gfc-mode_ext = MPG_MD_MS_LR;
}
