Constructor Detail

AllPass

public AllPass(int bufferSize)

Create. For derived classes.

Parameters:

bufferSize - Buffer size used for real-time rendering.

AllPass

public AllPass(int bufferSize,
               float srate)

Create. For derived classes.

Parameters:

bufferSize - Buffer size used for real-time rendering.

srate - sampling rate in Hz

Method Detail

init

protected void init()

Init and allocate.

addSource

public java.lang.Object addSource(Source s)
                           throws SinkIsFullException

Add source to Sink. Override to allow one input only and add to mixer with gain coefficient a and to delay 2. This will be called after init() so mixer will already have 2 inputs

Specified by:

addSource in interface Sink

Overrides:

addSource in class InOut

Parameters:

s - Source to add.

Returns:

object representing Source in Sink (may be null).

Throws:

SinkIsFullException

setM

public void setM(float del)
          throws java.lang.IllegalArgumentException

Set delay del. (=M/srate)

Parameters:

del - delay in seconds

Throws:

java.lang.IllegalArgumentException

setA

public void setA(float a)

Set filter parameter a.

Parameters:

a - allpas parameter

computeBuffer

protected void computeBuffer()

Compute the next buffer and store in member float[] buf.

Specified by:

computeBuffer in class Out
