-"""Audio latency performance test.
-
-Benchmark measuring how fast we can continuously repeat a short sound
-clip, while another clip is running in the background. In the ideal
-scenario we'd have zero latency processing script, seeking back to the
-beginning of the clip, and resuming audio playback.
-
-Performance is recorded as the average latency of N playbacks.  I.e., if we play
-a clip 50 times and the ideal duration of all playbacks is 1000ms and the total
-duration is 1500ms, the recorded result is (1500ms - 1000ms) / 50 == 10ms.
