Use vdrsync to extract the audio track and lame to transcode it: vdrsync.pl -audio-only /path/to/recording/ lame --mp2input vdrsync0.mpa recording.mp3
Thank you, I'm experimenting with the conversion. I'd like to boost the recorded volume a bit, since it's really low and listening to the file with an MP3 player is almost impossible.
Any idea ?
