Syntax

[Visual Basic]

Public Function TrimSilenceEnhanced (

nSilenceThresholdInitial as Int16,

nSilenceThresholdFinal as Int16

[C#]

public enumErrorCodes TrimSilenceEnhanced (

Int16 nSilenceThresholdInitial,

Int16 nSilenceThresholdFinal

);

[C++]

public: enumErrorCodes TrimSilenceEnhanced (

Int16 nSilenceThresholdInitial,

Int16 nSilenceThresholdFinal

);

Parameter	Description

nSilenceThresholdInitial	Number representing the silence threshold referred to the volume level for the initial portion of the recorded sound. Supported values are expressed with a linear volume in the range from 0 to 32767. If for example you should set a value of 800, any portion of sound having a volume level lower than 800 would be considered as silent. In case you should need to set a threshold value expressed in dB, before setting this parameter you could convert the value in dB into a linear value through the following formula (C syntax): ValueLinear = 32767 * pow (10, ValueInDB/20);
nSilenceThresholdFinal	Number representing the silence threshold referred to the volume level for the final portion of the recorded sound.

Return value

Value	Meaning

Negative value	An error occurred. Check the LastError property value in order to see the last error.
enumErrorCodes.ERR_NOERROR (0)	The method call was successful.
