Loudness (not amplitude) control
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
What Eric’s asking for is far more complex than average~. < http://en.wikipedia.org/wiki/Loudness> can serve as an intro/primer into the topic.
I suppose one way to patch a loudness control would be with a pfft~ and lookup tables for each bin. Tedious but could be effective. Should I sketch out the idea in any more detail?
Sorry, I don’t know of anything off-the-rack that will do it.
could you sketch it Peter ????? would be fantastic , i love math :D
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.
