NAME
toolame - MPEG-1 layer 2 audio encoder
SYNOPSIS
toolame [options] <infile> [outfile.mp3]
DESCRIPTION
toolame is a very fast (6x realtime on a 550mhz celeron) MPEG-1 layer 2
audio encoder with a command-line syntax nearly identical to that of
the lame MPEG-1 layer 3 audio encoder. Because of patent issues surrounding the layer 3 encoder, the ability of most mpeg audio players to
play layer 2 files, and the similarity in command-line syntax, toolame
makes a very good drop-in replacement for lame and other layer 3
encoders under most circumstances.
OPTIONS
-h, Show summary of options.
- -s sfrq,
- input sample rate in kHz (default is 44.1).
- -a downmix from stereo to mono.
- -x force byte-swapping of input.
- -m mode,
- channel mode: s/d/j/m (default is j).
- -p psy,
- psychoacoustic model 1/2 (default is 1).
- -b br, total bitrate in kbps (default is 192).
- -v lev,
- vbr mode
- -5 constant bitrate file at the lowest allowable
0 raises average bitrate by about 5%
5 raises average bitrate by about 20%
10 raises average bitrate by about 50%
15 raises average bitrate by about 75% - -f fast mode (turns off psy model).
- -q num,
- quick mode. only calculate psy model every num frames.
- -d emp,
- de-emphasis n/5/c (default is n).
- -c mark as copyright.
- -o mark as original.
- -e add error protection.
- -r force padding bit/frame off.
