Recently I need to convert several WAV files to MP3 format. I found the lame program can be used for this purpose. But due to my little knowledge in LAM I have difficulties to use the right options.
Thanksfully after reading the manual page and an article on the Internet, I found the following options generate the best quality and size ratio :
lame -V2 --vbr-new -q 2 -b 112 --lowpass 17 <WAV_file.wav>
And here is the picture of lame in action :
It took around 19 seconds to convert a 58 MB WAV file to MP3 format. Quite fast.
