Using Waveform and Auxiliary Audio

[The feature associated with this page, Waveform Audio, is a legacy feature. It has been superseded by WASAPI and Audio Graphs. WASAPI and Audio Graphs have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use WASAPI and Audio Graphs instead of Waveform Audio, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

This section demonstrates implementing waveform and auxiliary audio in your application. The following topics are discussed:

• Playing WAVE Resources
• Using the WAVEFORMATEX Structure
• Determining Nonstandard Format Support
• Example of Writing Waveform Data
• Processing the MM_WOM_DONE Message
