PortAudio - an Open-Source Cross-Platform Audio API
Many applications use PortAudio for Audio I/O. PortAudio provides a very simple API for recording and/or playing sound using a simple callback function or a blocking read/write interface. Example programs are included that play sine waves, process audio input (guitar fuzz), record and playback audio, list available audio devices, etc.

PyAudio Documentation — PyAudio 0.2.11 documentation
https://people.csail.mit.edu/hubert/pyaudio/docs/
To use PyAudio, first instantiate PyAudio using pyaudio.PyAudio() (1), which sets up the portaudio system. To record or play audio, open a stream on the desired device with the desired audio parameters using pyaudio.PyAudio.open() (2). This sets up a pyaudio.Stream to play or record audio.. Play audio by writing audio data to the stream using pyaudio.Stream.write(), or read …

The example below, excepted from patest_read_write_wire.c, shows how to open the default device, and pass data from its input to its output for a set period of time. Note that we use the default high latency values to help avoid underruns since we are usually reading and writing audio data from a relatively low priority thread, and there is ...
