I'm trying to modulate the amplitude of a sound from a file (using *~ and sfplay~) from the amplitude analysis of another input using fiddle~. The result is in dB, so I use jasch's db2a~ to change it to a linear value. Since the variation of the amplitude is a bit jerky, I tried to use qlim and a line~ to smooth the amplitude variation. It's still jerky... Does anybody has an idea of a more efficient way to do that?

The slide~ helps to smooth the variation, but it often clips... I'm gonna keep working on it.

Also, doesn't fiddle~ have another idea about dB values than standard

Max?, I think it neds a subtraction of 96 or something

But then again, why not use peakamp~ instead of fiddle~ for the
