Fixed bit rate jstereo 128kbps encoding, high quality (recommended):
|
|
|
|
|
|
|
|
lame -h sample.wav sample.mp3
|
|
|
|
|
|
|
|
Average bit rate 112kbps encoding:
|
|
|
|
|
|
|
|
lame --abr 112 sample.wav sample.mp3
|
|
|
|
|
|
|
|
Fast encode, low quality (no psycho-acoustics):
|
|
|
|
|
|
|
|
lame -f sample.wav sample.mp3
|
|
|
|
|
|
|
|
Variable bitrate (use -V n to adjust quality/filesize):
|
|
|
|
|
|
|
|
lame -h -V 6 sample.wav sample.mp3
|
|
|
|
|
|
|
|
Streaming mono 22.05 kHz raw pcm, 24 kbps output:
|
|
|
|
|
|
|
|
cat inputfile | lame -r -m m -b 24 -s 22.05 -- > output
|
|
|
|
|
|
|
|
Streaming mono 44.1 kHz raw pcm, with downsampling to 22.05 kHz:
