Hi,

Here's an online "game" I made for students to practice eliminating 
microphone feedback with a 7-band graphic EQ. You get a point only if 
the first band you choose to cut is the closest to the frequency of the 
acoustic feedback.

https://gsenna.github.io/LarsenEffectGame/

I know it probably should be easier to simulate the Larsen effect using 
a delay line with feedback, but I had some issues with that approach and 
didn't have the time to debug it properly.

Also, I was wondering about using csound.requestControlChannel to set a 
callback for reading a channel inside JS. I tried that, but couldn't 
make it work. Is a JS timer the only alternative for this now?


Cheers!

Hi,

@Dr. B: Great! Let me know how it goes.

@Oeyvind: Well, I think calling it fun might be a stretch. But keeping a 
score probably makes it a little bit more entertaining. By the way, I 
did know about your website and remember using it at some point while 
teaching about the different reverb topologies. I think a new WebAudio 
version would be great, so please feel free to pull whatever you need 
from the code (which is MIT-licensed). Actually, now that I've revisited 
your website just now, I see there are a bunch of other web "games" that 
could be developed for ear-training.

Cheers!
