Maybe you could use Grace Hopper's wire technique to implement your delay.



Very cool -- but since the delay shall have approx. 100 ms we will again end up with our 10 000 km cable ;-) -- BTW: She was a great person !

Sorry, I just skimmed the thread and saw 100nS.

I couldn't help wondering why you would want 100nS delay for Audio.

Certainly nobody would be able to hear 100nS of delay when it audio there is at least a few hundred nanoseconds delay going on . At least i say .

Right - you need at least 5 ms (for a trained ear) to notice that there are actually two sounds and 25 ms (also for a trained ear) to tell which one is first. Nevertheless, the nanosecond discussion is only related to accuracy/precision. The challenge is to have the 100 ms delay line as precise as possible and to make it calibratable. At least the thread has given me inspiration to try it with a digital delay. I will post intermediate results soon.
