Echo effect

[NeedUOS]

How would you proceed to program an echo effect? Like this with feedback, time (cathedral, room, ...).

For this, you need to create a DSP.
Take a look at SimplePlayer, there are some example of DSP.

The trick will be to save the main buffer in a temp buffer and add that buffer, with a delay to the main buffer that follow at each loop.
