Sliders (Windows Multimedia)

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 It has been superseded by Volume Controls.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

The slider controls are typically horizontal controls that can be adjusted to the left or right. These controls use the MIXERCONTROLDETAILS_SIGNED structure to retrieve and set control properties. The following table describes the types of sliders.
