Keeping to signals at the same level
Pretty straightforward, i guess... Is there a bunch of MSP objects (no
3rd party) to help keeping too signals at the same amplitude level ?
Let's say we have a 'dry' signal and one modified with a comb filter :
what's the simple way of keeping their amplitude to the same level ? How
to have the choice between RMS and peak ? Do i have to use omx objects,
normalize~, a simple combination of *~ and +~ and clip~ ? ...
thanks in advance

Trond Lossius's tl.balance~ object sounds like the thing.

Hmm, interesting, but not straight-forward. MSP doesn't know how 'loud' a signal is unless you define a period of time in which this can be measured. And then you're generally talking about compression/expansion.
For compression/expansion there is the omx dynamics suite. But this (of course) applies to all the dynamics in your sound.
If you would like to compensate only for the changes in amplitude made by one effect, you could measure the amplitude before and after the effect and compensate only with the difference. Would be an interesting version of a compressor though :)
I made my own simple compressor out of max objects, I even think it's somewhere on this list. Ah, yeah: https://cycling74.com/forums/index.php?t=msg&goto=82078&rid=3579&S=2751b9b23e60985a2feb6e6bd8844871#msg_82078
You could use it as a starting point..

Ahh, funny. You mean the objects on my ftp :-) ?
Thanks Owen. Nevertheless, i still want to do this without 3rd parties...

for the amplitude analysis, i use average~. that way u can choose between absolute and RMS and have the value as a signal.
peakamp~ also works ok but its absolute and outputs floats.
