How to -really- normalize ?
An oscillator. 4 waveforms. Measured with peakamp~, sine = 1., tri =
0.49, pulse = 0.49, saw = 0.69... How to boost the signal always to 1. ?
Normalize~ doesn't work because of the 'reset' message you have to send
(sometimes it even doesn't change anything), tap.normalize~ is a wahwah
/ lfo style effect, nothing helpfull in the bennies, nor the jimmies,
nor in any-ies. I made my own dirty kitchen patch to get some results
but i really wonder if there is a clean way (abstraction, external...)
to do this job, RMS and / or peak...
thanks in advance
best wishes

Try tl.balance~.

Isn't this what we call a compressor/expander? With an inifinite ratio in your case..

well "normalizing" is nonrealtime by definition, if you want
something similar in realtime you will always need some kind
of "reset" - or a permanent process such as in a compressor.
I think you should just use a hard limiter or compressor and then maybe turn it up.... If you have the bennies I think limit3~ is pretty good. Otherwise, as said before, just record and then do non realtime normalize after.
wouldn't it work if you just keep an account of the peak amplitudes of
your component wave forms and then multiply by a scaler in your way
out??
that is if you have three oscilators with peak amplitudes 0.4, 0.5 and
0.6 (adjusted with a *~ each), total peak amp 1.5, multiply(*~) by
0.66 and you get 1?? of course phase and frequency differences could
give you a total peak amp of less than 1.5, but it should work i
think...

This looks like a lovely set of objects but not yet UB?

No, unfortunately. I get a intel-based computer in a week or so, so the
motivation for porting to UB is increasing by the day... ;-)
I hope to have it done in the next two months. I have only a few
externals ported so far.

Glad to hear it. FWIW, I recompiled a few of your butterworth filter
objects from the included source. I needed them for an older piece I
was performing. Worked without a hitch.
Here's wishing you a speedy re-compile.
