Sets the `delay` in ms between `process_reverse_stream()` receiving a far-end frame and `process_stream()` receiving a near-end frame containing the corresponding echo. On the client-side this can be expressed as delay = (t_render - t_analyze) + (t_process - t_capture) where, - t_analyze is the time a frame is passed to `process_reverse_stream()` and t_render is the time the first sample of the same frame is rendered by the audio hardware. - t_capture is the time the first sample of a frame is captured by the audio hardware and t_process is the time the same frame is passed to `process_stream()`.
