Okay, I bit the bullet and bought a license. I like the program in terms of the interface and the ability to rather quickly select or create various effects. The sound quality is good. That being said, I'm not happy with the output file. It's way too loud and nearly distorted. Unfortunately, I lack the proper vocabulary to describe what I'm talking about, so please bear with me or offer a more proper description. When I open most sound files in Amadeus Pro, the waveform shows nicely delineated highs and lows. But when I open the output file from AudioRefurb, it's like seeing a giant block of solid line. It's as if I took the original file and amplified it excessively.
As such, I'd like to better be able to control the output file from AudioRefurb. (I think it's the gain I'm talking about.) Perhaps I'm missing some kind of setting or feature in the program. But I'd rather have a file where the audio is recorded a bit low than too high. As it stands, I'd almost be better off simply using AudioHijack to record AudioRefurb and then working with the Hijack file. I was doing that, but it became too much hassle to wait through the entire song in order to get the file.
It would also be nice if I were not limited to AIFF file format. It's the 21st century; there are other formats out there now.
