Pyro Audio Creator?

They are different and seperate programs, Audio Creator is a little buggy but good enough too put together Red Book CD's and of course you can use the MP3 coder inside Audio Creator and Sonar.

Peace Ben

Oh absolutly, for 60 odd dollars, you get an audio editor that allows you to write redbook cd'd (P&Q), you get the MP3 encoder normally 30 bucks if you want to get one just for Sonar and it has a couple of other useful tools.

On saying that, this is not an option for two track audio editing, yes you can do it but I only use the program for assembling CD's and encoding MP3's.

If you want a mastering two track editor, thery're better options out there.

Peace
