Lame MP3 与 Wav 互转

安装

sudo apt-get install lame

Fixed bit rate 128kbps encoding:

lame sample.wav sample.mp3

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:

cat inputfile | lame -r -m m -b 24 --resample 22.05 -- > output
