python使用PyGame播放Midi和Mp3文件的方法

本文实例讲述了python使用PyGame播放Midi和Mp3文件的方法。分享给大家供大家参考。具体实现方法如下：

    ''' pg_midi_sound101.py
    play midi music files (also mp3 files) using pygame
    tested with Python273/331 and pygame192 by vegaseat
    '''
    import pygame as pg
    def play_music(music_file):
      '''
      stream music with mixer.music module in blocking manner
      this will stream the sound from disk while playing
      '''
      clock = pg.time.Clock()
      try:
        pg.mixer.music.load(music_file)
        print("Music file {} loaded!".format(music_file))
      except pygame.error:
        print("File {} not found! {}".format(music_file, pg.get_error()))
        return
      pg.mixer.music.play()
      # check if playback has finished
      while pg.mixer.music.get_busy():
        clock.tick(30)
    # pick a midi or MP3 music file you have in the working folder
    # or give full pathname
    music_file = "Latin.mid"
    #music_file = "Drumtrack.mp3"
    freq = 44100  # audio CD quality
    bitsize = -16  # unsigned 16 bit
    channels = 2  # 1 is mono, 2 is stereo
    buffer = 2048  # number of samples (experiment to get right sound)
    pg.mixer.init(freq, bitsize, channels, buffer)
    # optional volume 0 to 1.0
    pg.mixer.music.set_volume(0.8)
    try:
      play_music(music_file)
    except KeyboardInterrupt:
      # if user hits Ctrl/C then exit
      # (works only in console mode)
      pg.mixer.music.fadeout(1000)
      pg.mixer.music.stop()
      raise SystemExit
