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()
