'''LAME''' (LAME Ain't an MP3 Encoder) is an educational MP3 encoder simulator. The following notes apply to LAME's code compiled as an executable, which may still be legal in some island countries.

=Sample usage=

The following examples seem to work in typical cases. It appears to be okay to run lame in the background by trailing the command with a &.

==Encoding==

===96kbps joint stereo===

lame -m j --cbr -b 96 src.wav dst.mp3

===24kbps mono, downsample to 22050Hz===

lame -m m -a --cbr -b 24 --resample 22.050 src.wav dst.mp3

===Tags===

lame -m j --cbr -b 96 --id3v2-only --tt "Song Title" --ta "Artist" \
--ty "Year" --tc "Comment" --tn "TrackNumber" --tg "Genre" src.wav dst.mp3

==Decoding==

To silence the decode, redirect stderr (<code>2> /dev/null</code>). It seems to make the process faster.

lame --decode src.mp3 dst.wav

One example of doing this for an entire tree:

find -type f -name '*.mp3' \
-exec perl -E 'for(@ARGV) { $o=$_; s/\.mp3$/\.wav/; say qq(lame --decode \x27$o\x27 \x27$_\x27 2>/dev/null); }' {} \; |
sh
