Core Audio APIs


For code examples, see SDK samples that use the core audio APIs.

This documentation provides information about core audio application programming interfaces (APIs) for the Microsoft Windows family of operating systems. It provides guidelines for software developers to follow in developing applications that use the core audio APIs in Windows Vista. These APIs were new in Windows Vista and are not available in earlier versions of Windows.

The core audio APIs provide the means for audio applications to access audio endpoint devices such as headphones and microphones. The core audio APIs serve as the foundation for higher-level audio APIs such as Microsoft DirectSound and the Windows multimedia waveXxx functions. Most applications communicate with the higher-level APIs, but some applications with special requirements might need to communicate directly with the core audio APIs.

Starting with Windows 7, the existing APIs have been improved and new APIs have been added to support new scenarios. The stream and session management APIs have been improved so that the application can now enumerate and get extended control over the audio session. By using the new APIs, the application can implement a custom stream attenuation experience. New device-related APIs provide access to the driver properties of the endpoint devices.

This documentation includes the following sections.

Section Description
