Effects.NormalizationAdvancedApply method

Previous pageReturn to chapter overviewNext page

Remarks

 

Normalizes the sound under editing respect to a given target level and outside of a given range of invalid peak levels. If you simply need to normalize a sound at 100% (0 dB) respect to its highest peak, use the Effects.NormalizationSimpleApply method.

 

A successful call to this method will fire the SoundEditStarted event followed by a number of SoundEditPerc events and finally by the SoundEditDone event.

 

For further details about methods related to the use of special effects refer to the Effects COM object.

 

 

Syntax

 

[Visual Basic]

control.Effects.NormalizationAdvancedApply (

nStartPosition as Long,

nEndPosition as Long,

fTargetLevelPerc as Single,

fBelowLevelPerc as Single,

fAboveLevelPerc as Single,

bRemoveDcOffset as enumBoolean

) as enumErrorCodes


 

[C++]

short control.Effects.NormalizationAdvancedApply (

long nStartPosition,

long nEndPosition,

float fTargetLevelPerc,

float fBelowLevelPerc,

float fAboveLevelPerc,

short bRemoveDcOffset

);


 

 

Parameter

Description

 

 

nStartPosition

Start position, expressed in milliseconds, of the affected sound range.

nEndPosition

End position, expressed in milliseconds, of the affected sound range.. If set to -1 the end position will be set to the end of the sound.

fTargetLevelPerc

Target peak level expressed in percentage.Typical values are 98% (-0.17 dB) or 100% (0 dB).

fBelowLevelPerc

Defines the lower peak level value, expressed in percentage, of the range where normalization effect will not be applied. Set this value to 100 if you want to apply normalization on all peak levels.

fAboveLevelPerc

Defines the higher peak level value, expressed in percentage, of the range where normalization effect will not be applied.  Set this value to 100 if you want to apply normalization on all peak levels.

bRemoveDcOffset

Boolean flag to request applying DC offset removal during normalization.

 

Supported values are the following:

Mnemonic constant

BOOL_FALSE

0

BOOL_TRUE

1
