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.
