Adding audio can be fairly straightforward, but where and how complex it is can depend on a number of factors and personal tastes. Here's an example of how to add audio to a Pygame framework:
import pygame
from pygame import mixer
import sys
def Example():
#initialize pygame
pygame.init()
#initialize sound mixer
mixer.init()
#create display
window = pygame.display.set_mode([640,480])
#load sound
sound = mixer.Sound('tone5.wav')
#main update loop
while True:
for event in pygame.event.get():
if event.type == pygame.KEYDOWN:
#if space is pressed, play sound
if event.key == pygame.K_SPACE:
sound.play()
#if escape is pressed, quit
if event.key == pygame.K_ESCAPE:
pygame.quit()
sys.exit(0)
#update window
pygame.display.update()
Example()
Keep in mind that Pygame and Pyglet typically only handle basic audio, if you want advanced audio like HRTF, EFX, or 3D positional audio you'll need to use a library like OpenAL, such as with my examples. I can provide other examples for Pyglet, or another Pygame example using OpenAL, if you prefer.
