OK. I will look at the reverb problem. I want to have the impulse responses of known good reverbs for: (1) Vocals. (2) Guitars. (3) Flutes. (4) Drums. Check impulses at "http://www.noisevault.com" or record yourself. Please convert to wav format and upload to ftp://ftp.funet.fi/incoming/audio/ Were (1)-(4) the most wanted reverb settings? What else? How to get most spacious but nearby vocals? Does people use other effects together with reverb for vocals? I can provide examples of good vocals if you want to examine them.
