C# Class javazoom.jl.decoder.Equalizer

The Equalizer class can be used to specify equalization settings for the MPEG audio decoder.

The equalizer consists of 32 band-pass filters. Each band of the equalizer can take on a fractional value between -1.0 and +1.0. At -1.0, the input signal is attenuated by 6dB, at +1.0 the signal is amplified by 6dB.

Private Methods

Method	Description
InitBlock ( ) : void
getBandFactor ( float eq ) : float	Converts an equalizer band setting to a sample factor. The factor is determined by the function f = 2^n where n is the equalizer band setting in the range [-1.0,1.0].
limit ( float eq ) : float
