''' 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()
