Python pyqt5 library can allow us to play wav file, there are some methods can play. In this tutorial, we will use some examples to tell you how to do.
Install pyqt5 in python
To play wav file using pyqt5, you should intall it first. You can install it using anaconda.
Then we can use pyqt to play wav file
You should import some python libraries
import sys from PyQt5.QtWidgets import QMainWindow,QApplication from PyQt5 import QtCore, QtMultimedia
We will play a wav file Alarm06.wav as an example.
Method 1: Use QtMultimedia.QMediaPlayer to play wav file
Here is an example code.
if __name__ == '__main__': app = QApplication(sys.argv) url = QtCore.QUrl.fromLocalFile("Alarm06.wav") content = QtMultimedia.QMediaContent(url) player = QtMultimedia.QMediaPlayer() player.setMedia(content) player.setVolume(50.0) player.play() sys.exit(app.exec())
Method 2: Use QtMultimedia.QSound to play wav file
Here is an example.
if __name__ == '__main__': app = QApplication(sys.argv) sound_file = 'Alarm06.wav' sound = QtMultimedia.QSound(sound_file) sound.play() sys.exit(app.exec())
Method 3: Use tMultimedia.QSoundEffect to play wav file
This method is much better than method 2, whicn provides more operations on wav file.
if __name__ == '__main__': app = QApplication(sys.argv) sound_file = 'Alarm06.wav' sound = QtMultimedia.QSoundEffect() sound.setSource(QtCore.QUrl.fromLocalFile(sound_file)) #sound.setLoopCount(QtMultimedia.QSoundEffect.Infinite) sound.setVolume(50) sound.play() app.exec() sys.exit(app.exec())
As to us, Method 3 is the best in all three methods, you can apply more control to the wav when playing.
