    Sound Help

    I am needing something that will allow me to play pure tones. I need to have control of three things: frequency, duration, and volume. I would use Beep except for it doesn't let you control volume and it's not asynchronous. If someone could point to a function or library I would be most appreciative.

    You could try something like OpenAL.

    I would use the sdl
    http://www.libsdl.org/intro/usingsound.html
    "code snippette from their site, play a tone"
    Code:
    Example:
    
    #include "SDL.h"
    #include "SDL_audio.h"
    {
        extern void mixaudio(void *unused, Uint8 *stream, int len);
        SDL_AudioSpec fmt;
    
        /* Set 16-bit stereo audio at 22Khz */
        fmt.freq = 22050;
        fmt.format = AUDIO_S16;
        fmt.channels = 2;
        fmt.samples = 512;        /* A good value for games */
        fmt.callback = mixaudio;
        fmt.userdata = NULL;
    
        /* Open the audio device and start playing sound! */
        if ( SDL_OpenAudio(&fmt, NULL) < 0 ) {
            fprintf(stderr, "Unable to open audio: %s\n", SDL_GetError());
            exit(1);
        }
        SDL_PauseAudio(0);
    
        ...
    
        SDL_CloseAudio();
    }
    I'm using the SDL graphic libraries at the moment and they are very nice. i havnt had time to work with sound yet but i'm hoping this will help you.
    Google SDL for more info
