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
