A set of example Python scripts to use ffmpegio for audio playback, interfacing with various audio player packages.

This script plays a test file using simpleaudio package's play_buffer() function.

The ffmpegio's stream reader populates the shared bytearray buffer incrementally as simpleaudio plays the buffer

This script plays a test file using pyaudio package's [callback IO mode] (https://people.csail.mit.edu/hubert/pyaudio/docs/#example-callback-mode-audio-i-o).

The pyaudio stream's callback function calls the read() function of the ffmpegio's stream reader.

Generate random test audio files (tone or noise) with ffmpegio.transcode() and ffmpegio.FilterGraph. The data is generated by FFmpeg's aevalsrc filter
