The latency introduced by tapping the touch screen is anywhere from 10-35ms, with 20ms being fairly typical on modern Android devices. To estimate tap-to-tone latency given round-trip latency, you can subtract the audio input latency (typically 5ms), and add the touch latency (typically 20ms). In other words, add 15ms to the round-trip latency.

Beginning with Android 4.3 (API level 18), a buffer count of one is sufficient for lower latency. All OpenSL ES interfaces for output effects preclude the lower latency path. The recommended sequence is as follows:
