Re: echo in the freq. domain
You can do an echo (delay) effect in the frequency domain using
convolution, exactly the same as you would for reverb - you would just
use a different impulse response (a sparser one, typically, in the time
However, the sparsity means that you can typically implement it
efficiently enough in the time domain, so there's not much point doing
it frequency-domain. Why do you want to do it?

I'd like to do a simple Echo effect in the frequency domain. Does anyone
remember any paper on the subject? There is a nice paper on freq domain
reverberation ("Frequency Domain Artificial Reverberation using Spectral
Magnitude Decay", Vickers E.), but couldn't find any on the echo....
