# Playing multiple sounds at once

Jump to: navigation, search

# Introduction

This tutorial will explain different methods attempted in getting multiple sounds to play concurrently, as well as the method that was most valuable.

# Steps

• Pick wav files desired to be played.
• Load wav files in code and save it to a variable that can be called later.
• Find a line of code that will play the sound.
• Find a line of code that will allow the sound to be played while different notes are being played at the same time.

# Libraries tested

• pydub
• multiprocessing
• multithreading
• swmixer
• pygame

# Pydub and Pygame

These two libraries were used in finding the best way to play a sound by itself.

Using pydub: Using pygame:

firstSound = pygame.mixer.Sound('/home/pi/laserharp-sounds/samples/ambi_dark.wav')
secondSound = pygame.mixer.Sound('/home/pi/laserharp-sounds/samples/ambi_choir.wav')
firstSound.play()
secondSound.play()

                                  or
firstSound = pygame.mixer.music('/home/pi/laserharp-sounds/samples/ambi_dark.wav')
secondSound = pygame.mixer.music('/home/pi/laserharp-sounds/samples/ambi_choir.wav')
firstSound.play()
secondSound.play()
