在Python中播放WAV文件

我尝试用 PyGame 来播放这样的 WAV 文件：

import pygame
pygame.init()

pygame.mixer.music.load("mysound.wav")
pygame.mixer.music.play()
pygame.event.wait()

但它改变了声音，我不知道为什么！ 我读这个链接解决方案，但无法解决我播放波形文件的问题！

对于这个解决方案，我不知道应该导入什么？

s = Sound() 
s.read('sound.wav') 
s.play()

对于这个解决方案 /dev/dsp 在新版本的 linux 中不存在：

from wave import open as waveOpen
from ossaudiodev import open as ossOpen
s = waveOpen('tada.wav','rb')
(nc,sw,fr,nf,comptype, compname) = s.getparams( )
dsp = ossOpen('/dev/dsp','w')
try:
  from ossaudiodev import AFMT_S16_NE
except ImportError:
  if byteorder == "little":
    AFMT_S16_NE = ossaudiodev.AFMT_S16_LE
  else:
    AFMT_S16_NE = ossaudiodev.AFMT_S16_BE
dsp.setparameters(AFMT_S16_NE, nc, fr)
data = s.readframes(nf)
s.close()
dsp.write(data)
dsp.close()

当我尝试 pyglet 时它给了我这个错误：

import pyglet

music = pyglet.resource.media('mysound.wav')
music.play()

pyglet.app.run()

您可以使用PyAudio。举个例子，在我的 Linux 上它可以工作：

#!usr/bin/env python  
#coding=utf-8  
  
import pyaudio  
import wave  
  
#define stream chunk   
chunk = 1024  
  
#open a wav format music  
f = wave.open(r"/usr/share/sounds/alsa/Rear_Center.wav","rb")  
#instantiate PyAudio  
p = pyaudio.PyAudio()  
#open stream  
stream = p.open(format = p.get_format_from_width(f.getsampwidth()),  
                channels = f.getnchannels(),  
                rate = f.getframerate(),  
                output = True)  
#read data  
data = f.readframes(chunk)  
  
#play stream  
while data:  
    stream.write(data)  
    data = f.readframes(chunk)  
  
#stop stream  
stream.stop_stream()  
stream.close()  
  
#close PyAudio  
p.terminate()
