I am thinking of learning the way to build a spectral delay patch in Max/MSP. I found a related patch in the forum archieve, but it crashes on PC and lack "Lifo" object in Mac. I tried to download Lobject pack but found that "Lifo" object in the pack does not work in OS X.

I was wondering if there is any good article or functioning patch for learning about spectral delay in addition to Dr. David Kim-Boyle's article "Spectral Delays with Frequency Domain Processing".

Wow, that's a very clean patch and works quite well.

It helps a lot.
Great thanks.


Nice patch, with some interesting interface possibilities.

Since delay is more fun with feedback, I added feedback control to the patch.

The pitch kept slowly rising on me which was unexpected. I adjusted the signal vector size from 64 to 128 and it stopped, even when I set the signal vector back to 64. Curious.

save as "spectral-delay-feedback-wrapper"

But the "feedback spectral delay" seems to consume too much CPU. There is certainly a need to make the patch become stereo, which might consume even more CPU.

Still wondering if there is a good way to do that...
