See schematic please.
It works, but VERY(!) slowly. :(
Whether it is possible to take the same effect faster?

Thanks.

Note:
Unzip, run and "Load" the test wav.

I have not opened it, but I am willing to be that you have updated the GUI refresh too many times per second. I limit the number of triggers to the Redraw primitive to about 15/second for something like this.

There are usually other tips, like reduce maths, reduce green triggers, etc.

I have checked up downloading and opening. All OK... I don't know what to correct.

Whether somebody can make an example like this, with faster work?
The practical example is necessary.
