Music in Python

[elvenstruggle]

Hey guys, I just want to know if there is any ways to add music to a python program (non-GUI, pure text program), and if there is, how?

Thanks a lot!

There is a great module called winsound.

import winsound
winsound.PlaySound("soundFile.wav",SND_ASYNC)
raw_input()

Just make sure to change the name of the file. FOr more reference check out this page: http://python.active-venture.com/lib/module-winsound.html

You can use module pygame in your program and play MP3 music files without having to create a GUI window:

# play a MP3 music file using module pygame
# (does not create a GUI frame in this case)
# pygame is free from: http://www.pygame.org/
# ene

import pygame

def play_music(music_file):
    """
    stream music with mixer.music module in blocking manner
    this will stream the sound from disk while playing
    """
    clock = pygame.time.Clock()
    try:
        pygame.mixer.music.load(music_file)
        print "Music file %s loaded!" % music_file
    except pygame.error:
        print "File %s not found! (%s)" % (music_file, pygame.get_error())
        return
    pygame.mixer.music.play()
    while pygame.mixer.music.get_busy():
        # check if playback has finished
        clock.tick(30)


# pick MP3 music file you have ...
# (if not in working folder, use full path)
music_file = "Drumtrack.mp3"

# set up the mixer
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)
pygame.mixer.init(freq, bitsize, channels, buffer)

# optional volume 0 to 1.0
pygame.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)
    pygame.mixer.music.fadeout(1000)
    pygame.mixer.music.stop()
    raise SystemExit

You can use PyAudio, or Pymedia (I havent use any but pyaudio is simple by looking with eyes). If that is too light, go for DLLs like Bass. Infact Im working with Bass.DLL and works fine for me, though I'm still learning it!

Thanks, this seems very easy. But can it only play .wav files? Is there a way to play mp3 files? Thanks a lot!

I have pointed out bass.dll and pymedia. If you choose bass.dll, you will have to face ctypes and for pure pythonic solutio, go for pymedia
Here are some links for pymedia:

http://pymedia.org/docs/index.html

This is an example from the pyMedia website that will play things for you. Note that you need command line arguments for this, if you want to change this just use things like raw_inputs().

PyMedia is older than the hills and hasn't been updated for a few years!

If you are looking for oldies but goodies there is also:
http://pysonic.sourceforge.net/index.html
It uses the ever so popular FMOD.DLL

In case you missed it, the PyGame module will play MP3 files.
