Thanks for the reply Lenard, I tried your suggestion and the pitch is
still not changing as the frequency increments with the loop.
This is a strange issue. if I manually change the value if frequency
before I run it, the sound changes. it is as if the pygame.mixer's
parameters are "Stuck"and can't be changed during runtime. Is there a
way I can verify that the pygame.mixer and the sound objects are
unloaded before I restart the loop?
Is there anything else I can try? Any links or snippet of code would
be greatly appreciated.
Here is the updated program
---------------------------------------------
import pygame
from pygame.locals import *
from sys import exit
#pgyame.display.set_mode must also come after the pygame.init. The
display is not necessary for mixer though. -Lenard
#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 # "do a pygame.quit rather than pygame.mixer.quit for
each loop -Lenard

Hi Brian,
You would probably have to do a pygame.quit rather than
pygame.mixer.quit for each pass of the loop. The
pgyame.display.set_mode must also come after the pygame.init. The
display is not necessary for mixer though.

How do I change the frequency of the Pygame.mixer by

Please see the example below where I am trying to initialize
the frequency at 44100 and then add 2000 to the frequency each
time it loops. In this example below the pitch does not
change, I really want it to change.
Any links or snippet of code would be greatly appreciated, Thanks!
