Class SynthesisFilter

java.lang.Object

javazoom.jl.decoder.SynthesisFilter

public final class SynthesisFilter
extends Object

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.

Constructor Detail

SynthesisFilter

public SynthesisFilter(int channelnumber,
               float factor,
               float[] eq0)

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).

Method Detail

reset

public void reset()

Reset the synthesis filter.

input_sample

public void input_sample(float sample,
                int subbandnumber)

Inject Sample.

input_samples

public void input_samples(float[] s)

calculate_pcm_samples

public void calculate_pcm_samples(OutputBuffer buffer)

Calculate 32 PCM samples and put the into the Obuffer-object.

deserialize

public static Object deserialize(InputStream in)
                          throws IOException

Throws:

IOException
