(almost) zero dynamics with a steady level or adsr

hello fellow max/msp’ers,

what would you be your preferred to turn a dynamic audio signal, preferably from a [groove] object into a steady-level signal,
without clipping or distortion,
level adjustable,
eventually running with an external & repetetive adsr applied?

i tried to compress up to the amount of brickwall limiting, but that doesn’t give me the desired effect of turning a dynamic signal into a highly congruent ambience, without the use of reverb or delay.

thank you to the one inclined, and for any hint pointing me somewhere!

You could try to do some spectral smearing over several fft frames…
There was a thread about such a technique some time ago. As you want to
get rid of attacks, just destroy them…. ;-)

(Ibook crashed yesterday – momentary stop in further developemnt, nevertheless:)

thanx very much for the suggestion. I had looked into an FFT solution, but generally found the resulting sound quality not convincing, which seems to be a well-known drawback of FFT in general.
So instead i am trying to apply rather typical sound engineering methods to the task of “ambientification”.
the [lbyl] object from the cnmat library turned out to be quite useful, as it kills sudden spikes easily.
[average~] then does some good things as well, although distortion does not permit the use of the absolute and rms mode in this matter. i am hoping to supply some half-working result by doing a frequency band split after adc and treat several different bands with different methods, not included delays or reverbs, as i want to keep the resulting ambience in it’s own room setup as far as possible.

unortunately, as i pointed out in brackets above, i am hindered by the breakdown of my osx-running computer momentarily, will nevertheless post positive achievements anytime i get back to having a proper work platform (soon!)

thanx again.
