BASS.NET API for the Un4seen BASS Audio LibraryUtilsGetNormalizationGain Method BASS.NET API for the Un4seen BASS Audio Library
Determines a gain factor (normalization), so that the maximum peak level of the stream will be at 0 dB.

Namespace: Un4seen.Bass
Assembly: Bass.Net (in Bass.Net.dll) Version: 2.4.12.0
Syntax

public static float GetNormalizationGain(
	string filename,
	float blockSize,
	double startpos,
	double endpos,
	ref float peak
)

Parameters

filename
Type: SystemString
The audio file to analyze.
blockSize
Type: SystemSingle
The block-size in seconds which will be used to scan the file (between 0.1 and 30 seconds).
startpos
Type: SystemDouble
The position (in seconds) where to start the calculation (between 0 and file duration, or -1 to scan from the beginning).
endpos
Type: SystemDouble
The position (in seconds) til where to perform the calculation (between 0 and file duration, or -1 to scan til the end; must be bigger than startpos).
peak
Type: SystemSingle
Returns the maximum peak level as a float value between 0.0 (silence) and 1.0 (0dB).

Return Value

Type: Single
The gain factor as a float value (or -1 on error) - a value of 1 means no amplification.
Remarks

You might use the gain factor as a multiplier to the sample data to apply a volume adjustment, so that the maximum peak level of the audio samples is at 0 dB.
