我尝试使用 pygame 播放 wav 文件,如下所示:
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!我阅读了此链接解决方案,但无法解决播放波形文件的问题!
对于这个解决方案,我不知道我应该导入什么?
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 它给了我这个错误:
import pyglet
music = pyglet.resource.media('mysound.wav')
music.play()
pyglet.app.run()
