delay modulation

[BobF]

Hello gang,

Even though I have now been on the forum for sometime now, I am still wondering, is there a wrong and right way to modulate a delay line? If yes, could someone please post examples of both. I searched the entire forum, but could not find any good examples at all. Many thanks in advance.

Later then, BobF.....

The important issue is how you interpolate. Linear interpolation is the simplest option and may be "good enough for rock n roll", however you will lose trebble. Allpass interpolation is preferred for slow modulation, If you have fast modulation then you can use some higher order interpolation, like a 4 point Lagrange. It really depends on your application.
