That could be a good feature request, but where would it belong? The FLAC decoding library could be enhanced to allow it to spit out adjusted WAVs, if requested. Something along these lines must already be done in order to have the FLACs play with ReplayGain. Aaron

But it discards all the advantages of ReplayGain: it is lossless, you can turn it on or off, per album or per track according to listener's taste. You lose that when you encode the audio to CDDA. -Ivo

But since the red book didn't specify level normalizing metadata (a la ReplayGain) I don't see a way to do it. I don't think it belongs in the audio data on the CD.

Regards - Richard PS: Yes, thought about normalize-audio but have heard its not really that good.

So, much for cd's in the Car. -Richard
