[clean-list] Playing sounds

[Jeremy Shaw]

Hello,

Have you considering writing some (partial) bindings for SDL?

http://www.libsdl.org/index.php

Looking at this page, I think it would be fairly trivial:

http://sdldoc.csn.ul.ie/guideaudioexamples.php

I think you would only need call the following functions:

SDL_Init (not shown on that page).
SDL_OpenAudio
SDL_MixAudio
SDL_PauseAudio
SDL_CloseAudio
SDL_Delay

I think you will find the SDL interface much easier to use that trying to call OS specific code, and as an added benefit, SDL is ported to linux, win32, MacOS, MacOS X, BeOS, and unofficially ported to Solaris, IRIX, FreeBSD, QNX, OSF/True64.

I hope to write a full set of bindings for clean and SDL someday. SDL already has an impressive number of bindings:
