Sounds and Audio Decoding/ Drive Access

I have not been able to find a resource for sending raw audio data to a sound device. I figure that the code would have to flow like this....

Enumerate Sound Devices
Connect or Talk to Device
Set Correct Command Registers or Options
Send Data

However, I didn't want to make it windows only and wonder if there isn't some ASM I could do as well... Then if someone could point me in the direction of sending raw sound information to the soundcard/onboard chip would be great. Also appreciated would be any resource to decode WAV, MIDI, MP3, etc. Or Accessing a drive directly to access raw audio data on a cd, dvd, etc. :confused:

I know this isn't a subject that you normally see here, but it was worth a shot... Thanks guys :)

I'm guessing this is a windows specific question.

I didn't want it to be, but it can. I'm not talking about using SndPlaySound or anything like that. I am wanting to know how to access sound devices for raw audio output.

For Win32, it sounds like you are looking for either Waveform Audio API or DirectSound. There are cross-platform libraries available that abstract the platform specific calls. One you could check out is fmod.

Ok, I figured out the following code form the references you posted.

Code:

---

        unsigned int NumDevs = 0;
        WAVEOUTCAPS wResult;
        char cGet = 0;

        NumDevs = waveOutGetNumDevs();

        if(NumDevs >0 && NumDevs != 1)
        {
                printf("Please Select 1 of the following %d devices.\n",NumDevs);
                for(int i = 0; i < (int)NumDevs; i++)
                {
                        waveOutGetDevCaps(i,&wResult,sizeof(wResult));
                        printf("Device %d: %s\n",i,wResult.szPname);
                }

                printf("Use Device Number: ");
                cin.get(cGet);
                waveOutGetDevCaps((int)cGet,&wResult,sizeof(wResult));
                printf("Using Wave Device %d: %s\n",(int)cGet,wResult.szPname);
        }
        else
        {
                waveOutGetDevCaps(0,&wResult,sizeof(wResult));
                printf("Using Wave Device 0: %s\n",wResult.szPname);
        }

Now, any help on playing the actual file?
