Syntax

 

[Visual Basic]

Public Function AppendAutomationItemAddFromRecorder (

hWndRecorderCtrl as IntPtr,

nStartPosition as Int32,

nEndPosition as Int32,

fVolume as Single

) as enumErrorCodes


 

[C#]

public enumErrorCodes AppendAutomationItemAddFromRecorder (

IntPtr hWndRecorderCtrl,

Int32 nStartPosition,

Int32 nEndPosition,

float fVolume

);


 

[C++]

public: enumErrorCodes AppendAutomationItemAddFromRecorder (

IntPtr hWndRecorderCtrl,

Int32 nStartPosition,

Int32 nEndPosition,

float fVolume

);


 

 

Parameter

Description

 

 

hWndRecorderCtrl

The value to pass to this parameter depends upon the nature of the recorder control that will provide the sound:

- If the recorder is an instance created through Audio Sound Recorder for .NET, use the Windows handle (Handle property) of the instance

- If the recorder is an instance created through Audio Sound Recorder API for .NET, use the identifier of the instance returned by its GetEditorInstanceId method

nStartPosition

Start position, expressed in milliseconds, of the range to load from the added editing session

nEndPosition

End position, expressed in milliseconds, of the range to load from the added editing session

fVolume

Volume level applied to the added song when it will be appended.

Supported values are expressed with a linear volume in the range from 0 to 100. In case you should need to set a volume expressed in dB, before setting this parameter you could convert the value in dB into a linear value through the following formula (C syntax):

VolumeLinear = 100 * pow (10, VolumeInDB/20);
