pyaudio

Introduction

PyAudio provides Python bindings for PortAudio, the cross-platform audio I/O library. With PyAudio, you can easily use Python to play and record audio on a variety of platforms. PyAudio is inspired by:

1. pyPortAudio/fastaudio: Python bindings for PortAudio v18 API.
2. tkSnack: cross-platform sound toolkit for Tcl/Tk and Python.

Remarks

Note: stream_callback is called in a separate thread (from the main thread). Exceptions that occur in the stream_callback will: 1.print a traceback on standard error to aid debugging, 2.queue the exception to be thrown (at some point) in the main thread, and 3.return paAbort to PortAudio to stop the stream. Note: Do not call Stream.read() or Stream.write() if using non-blocking operation. See: PortAudio’s callback signature for additional details : http://portaudio.com/docs/v19-doxydocs/portaudio_8h.html#a8a60fb2a5ec9cbade3f54a9c978e2710
