Multimedia Input
[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 It has been superseded by WASAPI and Audio Graphs.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.]
Windows provides functions that enable an application to receive multimedia input. The multimedia input functions were introduced in 16-bit Windows. Many of their features have been superseded by features in DirectX. For more information, see the DirectX documentation.
