pygame.quit() worked! I can now hear the pitch changing, Thanks!
Is there a way to do this without closing the pygame window everytime it
loops?
Here is the working code with the pygame window closing and reopening each
loop:
----------------------------------------
import pygame
from pygame.locals import *
from sys import exit
screen = pygame.display.set_mode((800, 600), 0, 32)
frequency = 44100
while True:
frequency = frequency + 2000
print frequency
pygame.mixer.pre_init(frequency, 16, 2, 4096)
pygame.init()
test_sound = pygame.mixer.Sound("check.wav")
mychannel = test_sound.play()
while pygame.mixer.get_busy() == True:
pass
pygame.quit()
screen = pygame.display.set_mode((800, 600), 0, 32) #to reopen the closed
window.
----------------------------------------------------------------------
