C# Класс javazoom.jl.decoder.SynthesisFilter

A class for the synthesis filter bank. This class does a fast downsampling from 32, 44.1 or 48 kHz to 8 kHz, if ULAW is defined. Frequencies above 4 kHz are removed by ignoring higher subbands.

Метод	Описание
SynthesisFilter ( int channelnumber, float factor, float eq0 ) : System	Contructor. The scalefactor scales the calculated float pcm samples to short values (raw pcm samples are in [-1.0, 1.0], if no violations occur).
calculate_pcm_samples ( Obuffer buffer ) : void	Calculate 32 PCM samples and put the into the Obuffer-object.
input_sample ( float sample, int subbandnumber ) : void	Inject Sample.
input_samples ( float s ) : void
reset ( ) : void	Reset the synthesis filter.
