Hi, sorry to disturb you, Iam a French student and I have a project, I need your help. sorry in advance for the quality of my English. I receive a signal with a delay (which is not constant) and I want to: -calculate the value of this delay (over time) by comparing with the original signal -emitting another signal with the same delay with speakers have you understood? how can I do with SynthMaker? thank you in advance thomas

I guess this could be done in ASM, but I'm leaving this part to ASM coders.
To consider there are following factors:
1. What is the maximum lenght of delay you wish to measure? 2. What kind of signals you deal with (digital or analog)? Maybe wrong wuestion; levels of noise? 3. What kind of dynamics you deal with? Continuous signals or impulses?
Then probably should be added some averaging routines depending on acceptable noise levels (for analog signals). ...and acceptable difference levels for signal comparison.
And signals could be compared. I guess first to find - are zero-crossing points. Then - similar data strings (real delay width should be longer than user selectable in order to get a pattern?) in order to determine which point could define the delay point. User selectable "pattern lenght" and "averaging options" (noise removal) options would probably help to adjust the accuracy. That's in time domain and with continuous signals.
For impulses, it's much easier, because it is about finding peak-to-peak difference.
