Dynamics processing in Sound Forge sounds different from the filter present in Cool Edit Pro. For long I've stayed with a particular setting:
But putting the same settings in SF doesn't give the same results - the waveform is more flattened, and sounds more squashed, too. Preliminary tweaking with attack and release times didn't help. SF version is pretty old - 4.5. For that matter, the Cool Edit Pro 1.1 is old too - latest is Adobe Audition 2.
