I need to derive a trigger from an audio stream ,preferably a detector with some kind of sensitivity setting and low ripple, searching the forums it seems that Bootsy's fast RMS might do the trick but i cannot find it anywhere , anyone have this thing lying around somewhere ?

Just bought Flowstone today , having fun
Thanks

Hi lalalandsynth and welcome to the Forum!
Bootsy's work is probably burried in the old Synthmaker forum. I can offer you my own onset detector which I use to trigger a synth with live audio (e.g. guitar).

An onset is detected if two criteria are met:
1. signal is a certain factor above delayed signal
2. signal is above noise floor
In general these criteria will be met for a certain period of time. At the end of that period, an onset event is reported along with a measure of the strength of the event (velocity).

The schematic includes optimized ASM code however I usually save a (more readable) code version along with the ASM.

Have fun!

Hello lalalandsynth,

If for some strange reason Martin's "OnsetDetector" does not work.

I found this one some time ago. Do NOT know who's it is though.

Good luck and welcome to the forum, BobF

Thanks guys , will try these out

How can I turn this onset trigger into a gate for an an envelope ?
