I prefer my sound output to me mono, not stereo. I've started using Audio Hijack Pro to monomize iTunes' audio using the built-in Monomizer plugin. The problem is that it's not the most intelligent algorithm in the world, and the result is that I lose a lot of the sound quality. Many instruments or voices that are as clear as day playing normally, in stereo, are virtually inaudible when monomized. The "Mono Enhancer" plugin (also built-in) only makes matters worse. Does anyone know of any other monomizing AudioUnit/VST/whatever plugin that's a little smarter? Or, for that matter, any better ways of going about this than using Audio Hijack Pro? I'm certainly open to new methods. I'm considering just getting some mono headphones. I used to have a set that had a hardware switch to toggle between mono and stereo. But I figure any conversion going on in there will be even less advanced than the Monomizer plugin. Any thoughts on this?
