Lame
LAME version 3.50 (www.sulaco.org/mp3)
GPSYCHO: GPL psycho−acoustic model version 0.74.
USAGE : lame [options] <infile> [outfile]
<infile> and/or <outfile> can be "−", which means stdin/stdout.
OPTIONS :
−m mode (s)tereo, (j)oint, (f)orce or (m)ono (default j)
force = force ms_stereo on all frames. Faster and
uses special Mid & Side masking thresholds
−b <bitrate> set the bitrate, default 128kbps
(for VBR, this sets the allowed minimum bitrate)
−s sfreq sampling frequency of input file(kHz) − default 44.1
−−resample sfreq sampling frequency of output file(kHz)− default=input sfreq
−−mp3input input file is a MP3 file
−−voice experimental voice mode
−v use variable bitrate (VBR)
−V n quality setting for VBR. default n=4
0=high quality,bigger files. 9=smaller files
−t disable Xing VBR informational tag
−−nohist disable VBR histogram display
−h use (maybe) quality improvements
−f fast mode (low quality)
−k disable sfb=21 cutoff
−d allow channels to have different blocktypes
−−athonly only use the ATH for masking
−r input is raw pcm
−x force byte−swapping of input
−a downmix from stereo to mono file for mono encoding
−e emp de−emphasis n/5/c (obsolete)
−p error protection. adds 16bit checksum to every frame
(the checksum is computed correctly)
−c mark as copyright
−o mark as non−original
−S don't print progress report, VBR histograms
Specifying any of the following options will add an ID3 tag
−−tt <title> title of song (max 30 chars)
−−ta <artist> artist who did the song (max 30 chars)
−−tl <album> album where it came from (max 30 chars)
−−ty <year> year in which the song/album was made (max 4 chars)
−−tc <comment> additional info (max 30 chars)
