I am a novice trying to make an ATRAC3 CD with SonicStage 3.1 I have some mp3 files and I converted them to WAV format which I understood is needed for SonicStage to cut a CD. But SonicStage rejects this file format as not supported. The file type is WAV(PCM). My question is are there different types of WAV file formats and do I need to make a different typle of WAV. Everything I have read says WAV is what SonicStage needs. Sorry if this is off topic here, but I am stumped and don't want to give up just yet on making an ATRAC3 CD.
