Python: realtime audio streaming with PyAudio (or something else)?

Question

Currently I\'m using NumPy to generate the WAV file from a NumPy array. I wonder if it\'s possible to play the NumPy array in realtime before it\'s actually written to the h

Answer 1

This has worked! Thanks for help!

def generate_sample(self, ob, preview):
    print("* Generating sample...")
    tone_out = array(ob, dtype=int16)

    if preview:
        print("* Previewing audio file...")

        bytestream = tone_out.tobytes()
        pya = pyaudio.PyAudio()
        stream = pya.open(format=pya.get_format_from_width(width=2), channels=1, rate=OUTPUT_SAMPLE_RATE, output=True)
        stream.write(bytestream)
        stream.stop_stream()
        stream.close()

        pya.terminate()
        print("* Preview completed!")
    else:
        write('sound.wav', SAMPLE_RATE, tone_out)
        print("* Wrote audio file!")

Seems so simple now, but when you don't know Python very well, it seems like hell.
