Test programs

Files
file	pa_minlat.c
	Experiment with different numbers of buffers to determine the minimum latency for a computer.
file	patest1.c
	Ring modulate the audio input with a sine wave for 20 seconds.
file	patest_buffer.c
	Test opening streams with different buffer sizes.
file	patest_callbackstop.c
	Test the paComplete callback result code.
file	patest_clip.c
	Play a sine wave for several seconds at an amplitude that would require clipping.
file	patest_converters.c
	Tests the converter functions in pa_converters.c.
file	patest_dither.c
	Attempt to hear difference between dithered and non-dithered signal.
file	patest_enumerate_default_latency.c
	List default latencies of available devices in table format.
file	patest_hang.c
	Play a sine then hang audio callback to test watchdog.
file	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.
file	patest_init.c
	Initialize and terminate PortAudio.
file	patest_latency.c
	Hear the latency caused by big buffers. Play a sine wave and change frequency based on letter input.
file	patest_leftright.c
	Play different tone sine waves that alternate between left and right channel.
file	patest_longsine.c
	Play a sine wave until ENTER hit.
file	patest_many.c
	Start and stop the PortAudio Driver multiple times.
file	patest_maxsines.c
	How many sine waves can we calculate and play in less than 80% CPU Load.
file	patest_mono.c
	Play a monophonic sine wave using the Portable Audio api for several seconds.
file	patest_multi_sine.c
	Play a different sine wave on each channel.
file	patest_out_underflow.c
	Count output underflows (using paOutputUnderflow flag) under overloaded and normal conditions.
file	patest_prime.c
	Test stream priming mode.
file	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() )
file	patest_ringmix.c
	Ring modulate inputs to left output, mix inputs to right output.
file	patest_sine8.c
	Test 8 bit data: play a sine wave for several seconds.
file	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.
file	patest_sine_formats.c
	Play a sine wave for several seconds. Test various data formats.
file	patest_sine_time.c
	Play a sine wave for several seconds, pausing in the middle. Uses the Pa_GetStreamTime() call.
file	patest_start_stop.c
	Play a sine wave for several seconds. Start and stop the stream multiple times.
file	patest_stop.c
	Test different ways of stopping audio.
file	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.
file	patest_suggested_vs_streaminfo_latency.c
	Print suggested vs. PaStreamInfo reported actual latency.
file	patest_sync.c
	Test time stamping and synchronization of audio and video.
file	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.
file	patest_toomanysines.c
	Play more sine waves than we can handle in real time as a stress test.
file	patest_two_rates.c
	Play two streams at different rates to make sure they don't interfere.
file	patest_underflow.c
	Simulate an output buffer underflow condition. Tests whether the stream can be stopped when underflowing buffers.
file	patest_unplug.c
	Debug a crash involving unplugging a USB device.
file	patest_wasapi_ac3.c
	Use WASAPI-specific interface to send raw AC3 data to a S/PDIF output.
file	patest_wasapi_eac3.c
	Use WASAPI-specific interface to send raw EAC3 data to a S/PDIF output.
file	patest_wire.c
	Pass input directly to output.
