Program Code – Advanced Game Audio Spatialization in Pygame
import pygame
import math
# Initialize Pygame mixer
pygame.mixer.init()
# Set up audio files (must be mono, not stereo, for spatialization to work!)
sound_files = {
'explosion': 'explosion.wav', # Replace with path to your sound files
'engine': 'engine.wav' # Replace with path to your sound files
}
# Load the sounds
sounds = {name: pygame.mixer.Sound(file) for name, file in sound_files.items()}
# Set audio positions (in cartesian coordinates, the origin is the screen center)
audio_positions = {
'explosion': (150, 50), # Example coordinates
'engine': (-100, 75) # Example coordinates
}
# Distance where the sound is 100% volume (closer than this will be at max volume too)
max_volume_distance = 200
# Game loop (for demonstration)
running = True
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
# Update positions here if they are dynamic (e.g., following a moving object)
# The listener position (usually the camera, or player position)
listener_position = (0, 0) # Update according to your game camera/player position
# Spatialize sounds
for name, position in audio_positions.items():
# Calculate distance and angle from the listener to the sound source
distance = math.hypot(position[0] - listener_position[0], position[1] - listener_position[1])
angle = math.atan2(position[1] - listener_position[1], position[0] - listener_position[0])
# Volume fades with distance (simple linear attenuation)
volume = max(0, 1 - (distance / max_volume_distance))
# Pan sound based on angle (-1 is left, 1 is right)
left_volume = max(0, volume * (1 - min(1, math.cos(angle))))
right_volume = max(0, volume * (1 - min(1, math.sin(angle))))
# Set the volume for each sound channel
sounds[name].set_volume(left_volume, right_volume)
# For this example, we're just constantly playing the sounds
# In an actual game, you'd trigger them based on game events
for sound in sounds.values():
if not sound.get_num_channels():
sound.play(loops=-1)
# ...rest of the game loop...
pygame.time.delay(100)
pygame.quit()
Code Output:
- The output of the code would be an application window (if there is one) along with spatialized sound effects. The explosions and engine sounds will seem to come from their respective directions, with the volume and panning changing in real-time as their positions or the listener’s position change.
Code Explanation:
The program is a basic demonstration of spatializing audio in a game using Pygame.
Firstly, it initializes Pygame’s mixer for handling audio and defines file paths for the sounds we want to spatialize.
After loading the sounds, we also set up initial positions for them in the game world. These positions are in terms of Cartesian coordinates, with the screen’s center as the origin.
Additionally, we define a variable for the maximum distance at which a sound will play at full volume.
Next, within the game loop, we keep checking for the quit event to be able to close the game cleanly. Here, we could also be updating the positions of the sounds if they were tied to moving objects.
We then define the listener’s position, which represents where the player, or the camera, is situated and update it accordingly as the game progresses.
The crucial part of the code is where we spatialize sounds. For each sound, we calculate its distance and angle relative to the listener. We use simple math to linearly attenuate the volume based on distance – the further away a sound source is, the quieter it becomes. As for the direction, we use the angle to pan the sound between the left and right speakers.
The cos and sin functions help us determine the volume for each ear. We set the volumes accordingly, ensuring neither left nor right can drop below zero.
Finally, we ensure that the sounds are played continually for the purpose of the demonstration. In a proper game setting, you would play these sounds in response to specific events happening on-screen.
