PeakValue Attribute

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 It has been superseded by MediaPlayer.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

The PeakValue attribute is a 16-bit amplitude value indicating the peak volume level.

Remarks

This attribute is stored in both the library and the digital media file.

Windows Media Player sets this value in either of the following instances:

  • After it has ripped a file.
  • After it has played a file (when the Auto Volume Leveling enhancement is enabled).

The Windows Media Format SDK constant for this attribute is g_wszPeakValue.

To determine whether you can change the value of this attribute, use the Media.isReadOnlyItem method.
