Hi Stefan,
I'm sorry i didn't get your first requirement "Starts when there has been no sound for 0,8 seconds". Could you be a little more specific?
If you need to have a strong control over the echo i think you should probably use tables instead of delay lines, because you can write and read to an from a table at any moment and at any point in the table.

Hi!
Im currently working with a project developing tactile feedback for stimulation of disabled children.
Im getting quite far in using a rough surface, a contact microphone and buttshaker. My signal path is something like mic->bandpass->filering->amplitude control of an oscillator->lowpass->speaker
i wish to get the sound a bit more interesting, so i would like to add an echoeffect something like: -Starts when there has been no sound (amplitude=0 after filtering) for 0,8 seconds. -Playbacks the last 1,6 seconds of sound (then there will be 0,8 seconds of noise and 0,8 seconds of silence) with 60% amplitude -Repeat the echo with decreasing amplitude (i.e 45, 30 and 0%)
I believe i should use delay lines but i have a hard time controlling them the way i want.
Some help would be really appreciated by me and the children
