Windows:  Important Note for Windows Vista

Existing applications that access Windows XP Acoustic Echo Cancellation (AEC) features via the DirectSound API will no longer obtain AEC when running on Windows Vista. These applications will still run, but their calls to AEC-specific DirectSound API calls will have no effect on the captured audio.

To learn how to obtain AEC in Windows Vista, See the Windows Vista AEC topics in the Windows SDK.
