    In callback mode, PyAudio will call a specified callback function (2) whenever it needs new audio data (to play) and/or when there is new (recorded) audio data available. Note that PyAudio calls the callback function in a separate thread. The function has the following signature callback (<input_data>, <frame_count>, <time_info>, <status_flag>) and must return a tuple containing …

    I think you don't need those threads (at least the audio thread) because PyAudio/PortAudio creates a new OS thread itself to call the callback() in. Just read the audio files and set up PyAudio in the main thread until the call to start_stream(). After that, the callback() is already running in the background.

    In addition, it is not safe to call any PortAudio API functions in the callback except as explicitly permitted in the documentation. Your callback function must return an int and accept the exact parameters specified in this typedef: typedef int PaStreamCallback ( const void *input, void *output, unsigned long frameCount,
