I'm working with simpleaudio in Python on a Windows 11 machine. I'm seeing really long delays for what is supposed to be an asynchronous library. Here is the guts of a test script: sample_rate = 44100 duration = 50 / 1000.0 t = np.linspace(0, duration, int(sample_rate*duration), False) tone = np.sin(2 * np.pi * 440 * t) audio = (tone * 32767).astype(np.int16) while True: try: time.sleep(.09) # TRACKING CODE.... print(f"Pre-xxx.play: {time.time()}") play_obj = sa.play_buffer(audio, 1, 2, sample_rate) # TRACKING CODE.... print(f"Post-xxx.play: {time.time()}\n") And here is some sample output: PS C:\python> py.exe .\beep_test.py Pre-xxx.play: 1748388885.2099779 Post-xxx.play: 1748388885.4194748 Pre-xxx.play: 1748388885.5100489 Post-xxx.play: 1748388885.8608859 Pre-xxx.play: 1748388885.9511144 Post-xxx.play: 1748388886.2871153 Pre-xxx.play: 1748388886.3772535 Post-xxx.play: 1748388886.7330158 Pre-xxx.play: 1748388886.8235033 Post-xxx.play: 1748388887.1881742 Pre-xxx.play: 1748388887.278986 Post-xxx.play: 1748388887.602071 Notice the sizeable delta of 0.209 - 0.365 seconds. What gives!? Any way to get these down to much smaller numbers? Is there a better Python audio library for this? Note: due to a bug/change required in the original simpleaudio library, I'm actually using this version: https://github.com/cexen/py-simple-audio Thank you for your help! Continue reading...
