How do i change the frequency,waveshape,waveform,duration
of the sound chip when programming in C++?

Where do i find these functions and to call them ?

Do i have to find the Datasheets to the sound card chips?

What OS are you on? One generally uses libraries and drivers.

First you need to give more specific information. You could be on an Atari, for all we know. You might read the forum's rules/FAQ and a "How to Post a Question" thread. There's a place in the control panel to register your OS, Language, etc. Always good to check a community's standards when you join. Polite, anyway.

Windows 98 or XP how do i use the sound functions and waveform functions ?

what libraries and drivers are for the sound functions and waveform functions?

When writing code in C++ how do i use the sound functions and waveform functions?

Klarre

I don't exactly get what you mean, but I guess you want to create an application that can play sound files. I should recommend you to take a look at fmod, which is a good sound API that is pretty simple to use. You can get it here http://www.fmod.org/

On the Atari consoles when programming games u have to use the sound and waveform functions to change the frequency,pitch,waveshape,envelope,waveform from the librarys inside the soundcard inside the Atari consoles the soundcard was a microcontroller with sounds built in its the samething when buying a soundcard it has a soundchip how do i trigger the sounds when writing Code in C++ please?

Markphaser

No not playing sound files i want to trigger the soundchips with C++ code

ivan

Why do you repeat the question? It has been told already in previous post:

-You must download a sound library ( i.e., fmod )

-You can not do that straight from c++ code

babbling

Modern operating systems do not allow direct access to the hardware. You can, however, create your own waveforms and then use a library that will play raw sound data for you. I know that SDL allows this. (www.libsdl.org)

Not strictly true, you just have to jump through the right hoops. It's easier to obtain other-party stuff or OEM stuff that has already made the jump.
