Hey all, I'm pretty new to PD, and been trying to absorb what I can in the last few weeks. I went through the trouble of making a customized ADSR generator to control oscillations which was pretty cool. (Then I ended up finding [breakpoint] after three days of trying to grasp it and felt like an idiot)

I am trying to make a sound like someone whispering "pssst", and I've hit a dead end. I've tried using my ADSR envelope to control the pitch of noise using a band pass filter but the values end up really low and I get a loud POP every time I bang a play.

What is the best way to go about this?

if you're using either [line] for your adsr, or [bp~] for your filter, then switch to [line~] (or [vline~]) and [vcf~]

also, you need to multiply the output by the resonance amount, because the filter also reduces volume.

Ahh thanks! [vcf~] works perfectly! Why does it work better than [bp~]?

because [vcf~] uses a audiorate (usually 44100 times per second) signal to modulate its cutoff value.

[bp~] uses control rate messages, so its accuracy is much less, and that's why you get pops and clicks from weird jumps.
