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
希望本文所述对大家的python程序设计有所帮助。
