Controlling Wave World or Radio Waves with sound?

[Mylenium]

I don’t think so. Don’t use Radio Waves much, but as far as I remeber all emission is continuous once it starts.. You may be better off by keyframing e.g. instances of the Circle effect in a sub-comp and then letting this be time-remapped triggered by Soundkeys.

Try linking the Radio Wave > Wave Motion > Frequency to the Sound Keys Output 1 (if that’s the Range you used) with an expression.

Alt Click the Frequency Stopwatch then pickwhip to the Output 1(the little @ looking middle box when you Alt Click, drag that to the Output 1 stopwatch) , to get this on the layer with the Radio Waves:

effect(“Sound Keys”)(“Output 1”)

I had the Radiowaves on the same layer as the Sound Keys so if they’re on different layers the expression will look different.

If there are big numbers for the output 1, like 75 in my test, then you get a huge band when the sound goes off, so try dividing the Frequency expression by 5 or 10, so the expression for Frequency looks like this:

effect(“Sound Keys”)(“Output 1”) / 5

or
effect(“Sound Keys”)(“Output 1”) / 10

Also look at the Output 1 keyframe values (I’m assuming you hit the Apply button in Sound Keys to make keyframes) up and down the timeline, and if there is no “0” values between the positive values, then you will get a constant stream of radiowaves, not a nice clean cutoff like you want. You need to fool with Sound keys until you get Positive values (when your Snare are Snaring) and Zero values (when you snares are not making noise).

Also if the snare sounds are to close or bunched up, and hence the Radio wave are bunched up, you can spread the whole mess out by increasing the “Expansion” (also under Wave Motion), or you can bunch them closer by decreasing the expansion.
