I created a flanger the other day (eventually) and it sounds pretty good. I tried altering the delay times to create a chorus effect. I read that chorus delay times should be between 20-30 ms (opposed to flangers 0-10 ms delay), so that's what I did using an allpass~ filter. It should work as all I have really done is alter the delay times from my working flanger (though I used comb~ instead of allpass~ in the flanger).
It doesn't really seem to be doing much except making the source signal a bit louder. Other than that I hear very little (or no) difference.
Another thing is that I read that you can create a stereo flanger with wide stereo field by putting the oscillators 1/4 of a wavelength out of phase. Tried this too...no success!
I was hoping someone would be able to point me in the right direction. I'd really appreciate it.
Here's the code i've got so far. It's supposed to be a dual-voice chorus, but it may be completely wrong!
