This kind of mastering can certainly be done in Audacity, but it would take longer since not all previews could be done in real time. All of the required software (high quality EQ, compression, reverb) either already exists, or could be written in Nyquist or Csound.

For that matter, now that I think of it, a high-quality CD mastering application could be written for Csound with an interactive Python GUI, and it would probably be able to run in real time on a fast PC. But it is not a completely trivial task, since one would want some sort of automation (remember how I adjusted the controls).

Pure Data would also be a good choice as an open source system suitable for creating a mastering application.

Regards,
Mike
