How to play sound in python12 min read
Reading Time: 8 minutesPlaying sound in Python is a fairly easy process, but there are a few things you need to know in order to do it correctly. In this article, we will go over the basics of playing sound in Python, as well as some of the more advanced techniques.
The first thing you need to do is import the necessary libraries. The following code will do this for you:
import pygame
import time
Next, you need to create a Pygame instance. This will allow you to control the sound playback. The following code will do this:
pygame.init()
Once you have done that, you can start playing sounds. The following code will play a sound file named "sound.wav":
pygame.mixer.init()
sound = pygame.mixer.Sound("sound.wav")
sound.play()
You can also play sounds directly from a string. The following code will play a sound named "ding.wav":
pygame.mixer.init()
sound = pygame.mixer.Sound("ding.wav")
sound.play()
By default, sounds will play once and then stop. If you want a sound to keep playing, you need to use the loop property. The following code will play the sound "ding.wav" repeatedly:
pygame.mixer.init()
sound = pygame.mixer.Sound("ding.wav")
sound.play()
sound.loop = True
You can also control the playback speed of a sound. The following code will play the sound "ding.wav" at half speed:
pygame.mixer.init()
sound = pygame.mixer.Sound("ding.wav")
sound.play()
sound.speed = 0.5
You can also pause and resume playback using the following code:
pygame.mixer.pause()
pygame.mixer.resume()

Can you play audio in Python?
Yes, you can play audio in Python using the built-in module, "audioop." This module can be used to play back audio files or generate audio signals.
To play an audio file, you first need to import the "audioop" module. Then, you can use the "play" function to play the audio file. The "play" function takes two arguments: the filename of the audio file and the playback speed. The playback speed can be either "normal" or "reverse."
Here’s an example of how to play an audio file:
import audioop
audio = audioop.open("myfile.wav", "rb")
audioop.play(audio, 0.5)
This code will play the audio file "myfile.wav" at half speed.
You can also generate audio signals using the "audioop" module. The "sine" function takes two arguments: the frequency of the signal and the duration. Here’s an example of how to generate a sine wave:
import audioop
frequency = 440
duration = 1
audio = audioop.sine(frequency, duration)
This code will generate a sine wave with a frequency of 440 Hz and a duration of 1 second.

How do I play a .wav file in Python?
Python has a few different ways to play back audio files. In this article, we’ll show you how to play a .wav file using the Pygame library.
First, you’ll need to install the Pygame library. You can do this by running the following command in your terminal:
sudo pip install pygame
Once the Pygame library is installed, you can create a new Python file and import the Pygame library.
import pygame
Next, you’ll need to create a pygame.Surface object. This object will be used to store the audio data.
surface = pygame.Surface(16, 16)
The audio data will be stored in a buffer. You can create a buffer object by running the following command:
buffer = pygame.Buffer()
Now, you can load the audio data into the buffer object.
buffer.load(filename)
The filename is the path to the .wav file you want to play.
Once the audio data is loaded, you can play it back by calling the pygame.sound.play() function.
pygame.sound.play(buffer)
You can also control the playback volume by setting the pygame.mixer.music.volume property.
pygame.mixer.music.volume = 0.5
