Another hiss fan, eh?
So I think you'll appreciate this story. I was reviewing Waves' Aphex Aural Exciter plug-in, which has an option to add in the noise and other artifacts. I said I just didn't get why they did that, wouldn't it be considered an advantage of software to compensate for those problems? The software designer said that when they did A-B blind testing with and without noise, the people evaluating the plug-in usually chose the version with the noise as sounding "right."
