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. ## LIMITATIONS The input file must have 16 bits per sample. ## SEE ALSO [**lame**(1)](/lame/1.md), [**oggenc**(1)](/oggenc/1.md). ## AUTHOR toolame was written by Michael Cheng \.
