DitherDemo?is like a magnified version of dither. It shows you how dither works, up close and personal! Using this plugin, you can hear what the noise floor sounds like when various dither types are in use (including the Airwindows boutique dithers, and the Airwindows freebies in DitherTo). You can also hear truncation, flat dither, and good old TPDF!
This isn’t for using on tracks, it’s a learning tool. Though I guess you could use it as a bitcrusher!
