Questions tagged [lame]
LAME is a free software codec used to encode/compress audio into the lossy MP3 file format. The name LAME is a recursive acronym for "LAME Ain't an MP3 Encoder". Use this tag for questions about LAME encoder, using LAME with FFmpeg, etc. Also add the mp3 tag. Questions about programming using LAME are off topic and should be asked on stackoverflow.com.
