Constructor Detail

LPCAnalysisResynthesis

public LPCAnalysisResynthesis(int p)

Apply LPC analysis-resynthesis.

Parameters:

p - prediction order, i.e. number of LPC coefficients to compute.

Method Detail

applyInline

public void applyInline(double[] data,
               int off,
               int len)

Description copied from interface: InlineDataProcessor

Perform some in-place processing on the given data.

Specified by:

applyInline in interface InlineDataProcessor

Parameters:

data - data

off - off

len - len

processLPC

protected void processLPC(LpcAnalyser.LpCoeffs coeffs,
              double[] residual)

Process the LPC coefficients and/or the residual in place. This method does nothing; subclasses may want to override it to do something meaningful.

Parameters:

coeffs - the LPC coefficients

residual - the residual, of length framelength

main

public static void main(String[] args)
                 throws Exception

Throws:

Exception
