[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

The put_Pan method sets the pan level.

Syntax

HRESULT put_Pan(
  [in] double Pan
);

Parameters

[in] Pan

Specifies the pan level. Possible values range from –1.0 to 1.0, as follows.

Value	Description
-1	Full left
0	Center
1	Full right

Return value

If the method succeeds, it returns S_OK. Otherwise it returns an HRESULT error code.

Remarks

In a stereo recording, setting the pan level to -1.0 or 1.0 sends the entire signal to one channel. The other channel records silence. Panning has no effect for a mono recording.
