Loudness (not amplitude) control

Sep 11 2012 | 2:41 pm

Are there any patches/objects out there that attempt to do (psychoacoustic) loudness control, as opposed to [*~] amplitude control?

[average~] :) u can calculate the differences between rms and normal peak to provide dedicated level control i guess . ive never done that but i saw the compressors logic where "you are" controlling it automatically with reversed ratio – because you want to affect quiet signals not peaks

ps:if there are some objects.patches.externals i would also like to know

There’s a loudness output in analyzer~, downloadable at the CNMAT site. (There’s also a standalone loudness object.) You’d have to compensate for the delay inherent in the analysis, but that should get you started.
