Re: [pygame] Re: Some way to pickle or otherwise save a pygame.mixer.Sound object?
The wav format is not super complicated, you could split every track into
15 second chunks and read them off disk as needed so you always have one
extra 15 second chunk than you currently need. You could probably even make
fake file objects that mapped to the same file on disk using seeks, and use
that to buffer over the files. Then you could throw out the buffers as they
were used up.

Re: [pygame] Re: Some way to pickle or otherwise save a pygame.mixer.Sound object?
Just to be clear, you need to play two different multi-minute sounds at
once?
Because your example has one 13-minute track and one 3-second track. If
those are the sounds you need to play at the same time, why don't you just
preload the 3-second one into a pygame.mixer.Sound object and play it
whenever you need it, and play the 13-minute one with pygame.mixer.music?

Well so much for using OGG (and probably MP3) to speed up preloading. With
my 13 minute mono soundfiles, it takes 7.3 seconds to preload the wav file
(44.1hz, 16 bit, mono) and 43.6 seconds to preload the OGG file... I have a
feeling it's uncompressing it during preload.

This method of playing MP3 works beautifully without preloading, but can

I don't imagine anyone knows of a way to play two sound files
simultaneously using pygame.mixer.music? Or some other solution in Python
under Linux that would do it reliably? I suppose I could slave two
instances of mplayer, but I'd of course prefer to not be forking out

There's no menus, it just loads and waits for the user to trigger sounds on
a keypad. I could play a single sound while the other sounds are loading,
but I'd prefer to have it fully functional at startup if possible.
Re: [pygame] Re: Some way to pickle or otherwise save a pygame.mixer.Sound object?
I recommend saving the sound as a raw buffer. First in a separate script:
sound = pygame.mixer.Sound("music1.wav")
open("music1.buf", "wb").write(sound.get_raw())
Then in your game:
sound = pygame.mixer.Sound(buffer=open("music1.buf", "rb").read())
I found about 4x speedup of reading a large file on my desktop using this
method. That may or may not be enough for you, especially if you combine

A very good idea, and the route I originally took, but as far as I can tell
pygame.mixer.music doesn't support polyphony, and I occasionally need to
play multiple sounds at once.

Re: [pygame] Re: Some way to pickle or otherwise save a pygame.mixer.Sound object?
I think the answer that sticks out to me is that if these are musical horn
sounds, you might consider using pygame.mixer.music, which will stream the
sounds as needed. However, this won't work if you have other music playing
or if you want multiple horns to be able to play at the same time.
A second solution is to load the sounds in the background of the game,
especially if you're going to launch on a menu where the sounds won't be
needed. You can pre-populate a dictionary with dummy sounds and use a
thread to go through and load each sound into the dictionary while the user
interacts with the menu.
SOUND_PATH_MAPPING = {'horn_funny': 'horn_funny.ogg', 'horn_sad':
'extra_sounds/horn_sad.wav'}
SOUNDS = {name: None for name in SOUND_PATH_MAPPING}
def load_sounds():
for name, path in SOUND_PATH_MAPPING:
SOUNDS[name] = pygame.mixer.Sound(path)
def load_sounds_background():
thread.start_new_thread(load_sounds, ())
If there's a legitimate chance that the player might try to use the horn
sounds before they've finished loading, just have the horn logic check for
Nones before trying to play or have a dummy sound object with a play method
that does nothing.
