-/** @file patest_stop.c
-    @ingroup test_src
-    @brief Test different ways of stopping audio.
-
-    Test the three ways of stopping audio:
-        - calling Pa_StopStream(),
-        - calling Pa_AbortStream(),
-        - and returning a 1 from the callback function.
-
-    A long latency is set up so that you can hear the difference.
-    Then a simple 8 note sequence is repeated twice.
-    The program will print what you should hear.
