详解python播放音频的三种方法

  pygame.mixer.init()
  pygame.mixer.music.load(self.wav_file) 
  pygame.mixer.music.set_volume(0.5) 
  pygame.mixer.music.play()

from PyQt5 import QtMultimedia
from PyQt5.QtCore import QUrl
file = QUrl.fromLocalFile(wav_file) # 音频文件路径
content = QtMultimedia.QMediaContent(file)
player.setMedia(content)
player.setVolume(50.0)
player.play()

import pyaudio
import wave
import sys
chunk = 1024
wf = wave.open('gyh.wav', 'rb')
p = pyaudio.PyAudio()
stream = p.open(format=p.get_format_from_width(wf.getsampwidth()),
        channels=wf.getnchannels(),
        rate=wf.getframerate(),
        output=True)
data = wf.readframes(chunk)
while len(data) > 0:
  stream.write(data)
  data = wf.readframes(CHUNK)
stream.stop_stream()
stream.close()
p.terminate()
