pygame.mixer.Sound.play is irregular although fired regularly
I currently try to repeat a sound every x ms - where x is dependent on an UDP packet I receive via socket - and I decided to use pygame for that. I used this SO answer to repeat something every x ms: http://stackoverflow.com/a/18954902/3475778
But now I have the problem, that the sound is played very irregular and made a minimal-working example where the problem persists:
import pygame from pygame.locals import * pygame.mixer.init() sound = pygame.mixer.Sound('sound.wav') def play_sound(): sound.stop() sound.play() pygame.init() clock = pygame.time.Clock() pygame.time.set_timer(USEREVENT+1, 200) while True: # clock.tick(30) for event in pygame.event.get(): if event.type == USEREVENT+1: play_sound()
Here is the waveform of what I have recorded from the script via Audacity:
You see that for some reason some samples were played longer than the others. Not very nice for some kind of metronome I want to build.
