[linux-audio-user] single WAV + CUE -> multiple FLACs

[Tobias Ulbricht]

Hi.

Well, you'll see below what I did in the last hour ...(stupid me)
short answer: try flac --cuesheet="test.cue" ...

or try my script, you'll get some #num.wav files out, which you could process by:

bash# for i in *.wav; do flac $i; done

hope somethings help, cheers, tobias.
