| ► loopback | |
| paqa_devs.c | Self Testing Quality Assurance app for PortAudio Try to open devices and run through all possible configurations. By default, open only the default devices. Command line options support opening every device, or all input devices, or all output devices. This test does not verify that the configuration works well. It just verifies that it does not crash. It requires a human to listen to the sine wave outputs |
| paqa_dither.c | Tests the dither scaling and conversion accuracy in pa_converters.c |
| paqa_errs.c | Self Testing Quality Assurance app for PortAudio Do lots of bad things to test error reporting |
| paqa_latency.c | Test latency estimates |
| paqa_macros.h | |

| ▼ test | |
| 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_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_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_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 |
| patest_write_stop_hang_illegal.c |
