How to play sound with Pyqt5 QtMultimedia?

Question

def play_tts(self,file_path):

   file = open(file_path)

   mixer.init()

   mixer.music.load(file)

   mixer.music.play()

   while mixer.music.get_busy():

       time.sleep(0.03)

       if window.ttsIs:

           break

   mixer.stop()

   mixer.quit()

   file.close()

   remove(file_path)

How do I write the above code with QtMultimedia?

Can you give me an example?

Answer 1

If the file is a .wav then just use QSound:

import os

import sys

from PyQt5 import QtCore, QtMultimedia

CURRENT_DIR = os.path.dirname(os.path.realpath(__file__))

def main():

    filename = os.path.join(CURRENT_DIR, "beal.wav")

    app = QtCore.QCoreApplication(sys.argv)

    QtMultimedia.QSound.play(filename)

    # end in 5 seconds:

    QtCore.QTimer.singleShot(5 * 1000, app.quit)

    sys.exit(app.exec_())

if __name__ == "__main__":

    main()

If you want to play more formats then you should use QMediaPlayer:

import os

import sys

from PyQt5 import QtCore, QtMultimedia

CURRENT_DIR = os.path.dirname(os.path.realpath(__file__))

def main():

    filename = os.path.join(CURRENT_DIR, "sound.mp3")

    app = QtCore.QCoreApplication(sys.argv)

    player = QtMultimedia.QMediaPlayer()

    def handle_state_changed(state):

        if state == QtMultimedia.QMediaPlayer.PlayingState:

            print("started")

        elif state == QtMultimedia.QMediaPlayer.StoppedState:

            print("finished")

            QtCore.QCoreApplication.quit()

    player.stateChanged.connect(handle_state_changed)

    url = QtCore.QUrl.fromLocalFile(filename)

    player.setMedia(QtMultimedia.QMediaContent(url))

    player.play()

    sys.exit(app.exec_())

if __name__ == "__main__":

    main()
