Files
	pa_minlat.c
	Experiment with different numbers of buffers to determine the minimum latency for a computer.

	patest1.c
	Ring modulate the audio input with a sine wave for 20 seconds.

	patest_buffer.c
	Test opening streams with different buffer sizes.

	patest_callbackstop.c
	Test the paComplete callback result code.

	patest_clip.c
	Play a sine wave for several seconds at an amplitude that would require clipping.

	patest_converters.c
	Tests the converter functions in pa_converters.c.

	patest_dither.c
	Attempt to hear difference between dithered and non-dithered signal.

	patest_dsound_find_best_latency_params.c

	patest_dsound_low_level_latency_params.c

	patest_dsound_surround.c

	patest_enumerate_default_latency.c
	List default latencies of available devices in table format.

	patest_hang.c
	Play a sine then hang audio callback to test watchdog.

	patest_in_overflow.c
	Count input overflows (using paInputOverflow flag) under overloaded and normal conditions. This test uses the same method to overload the stream as does patest_out_underflow.c – it generates sine waves until the cpu load exceeds a certain level. However this test is only concerned with input and so doesn't output any sound.

	patest_init.c
	Initialize and terminate PortAudio.

	patest_jack_wasapi.c

	patest_latency.c
	Hear the latency caused by big buffers. Play a sine wave and change frequency based on letter input.

	patest_leftright.c
	Play different tone sine waves that alternate between left and right channel.

	patest_longsine.c
	Play a sine wave until ENTER hit.

	patest_many.c
	Start and stop the PortAudio Driver multiple times.

	patest_maxsines.c
	How many sine waves can we calculate and play in less than 80% CPU Load.

	patest_mono.c
	Play a monophonic sine wave using the Portable Audio api for several seconds.

	patest_multi_sine.c
	Play a different sine wave on each channel.

	patest_out_underflow.c
	Count output underflows (using paOutputUnderflow flag) under overloaded and normal conditions.

	patest_prime.c
	Test stream priming mode.

	patest_read_record.c
	Record input into an array; Save array to a file; Playback recorded data. Implemented using the blocking API (Pa_ReadStream(), Pa_WriteStream() )

	patest_read_record_wasapi.c

	patest_read_write_wire_wasapi.c

	patest_ringmix.c
	Ring modulate inputs to left output, mix inputs to right output.

	patest_sine8.c
	Test 8 bit data: play a sine wave for several seconds.

	patest_sine_channelmaps.c
	Plays sine waves using sme simple channel maps. Designed for use with CoreAudio, but should made to work with other APIs.

	patest_sine_formats.c
	Play a sine wave for several seconds. Test various data formats.

	patest_sine_srate.c

	patest_sine_time.c
	Play a sine wave for several seconds, pausing in the middle. Uses the Pa_GetStreamTime() call.

	patest_start_stop.c
	Play a sine wave for several seconds. Start and stop the stream multiple times.

	patest_stop.c
	Test different ways of stopping audio.

	patest_stop_playout.c
	Test whether all queued samples are played when Pa_StopStream() is used with a callback or read/write stream, or when the callback returns paComplete.

	patest_suggested_vs_streaminfo_latency.c
	Print suggested vs. PaStreamInfo reported actual latency.

	patest_sync.c
	Test time stamping and synchronization of audio and video.

	patest_timing.c
	Play a sine wave for several seconds, and spits out a ton of timing info while it's at it. Based on patest_sine.c.

	patest_toomanysines.c
	Play more sine waves than we can handle in real time as a stress test.

	patest_two_rates.c
	Play two streams at different rates to make sure they don't interfere.

	patest_underflow.c
	Simulate an output buffer underflow condition. Tests whether the stream can be stopped when underflowing buffers.

	patest_unplug.c
	Debug a crash involving unplugging a USB device.

	patest_wasapi_ac3.c
	Use WASAPI-specific interface to send raw AC3 data to a S/PDIF output.

	patest_wasapi_eac3.c
	Use WASAPI-specific interface to send raw EAC3 data to a S/PDIF output.

	patest_wire.c
	Pass input directly to output.

	patest_wmme_find_best_latency_params.c

	patest_wmme_low_level_latency_params.c

	patest_write_stop.c
	Play a few seconds of silence followed by a few cycles of a sine wave. Tests to make sure that pa_StopStream() completes playback in blocking I/O.
