Constructor Detail

SpatialMixer

public SpatialMixer(int bufferSize,
                    int n,
                    java.lang.String hrtf_data)

Create stereo Spatialized mixer

Parameters:

bufferSize - Buffer size used for real-time rendering. For stereo must be 2X input buffersize

n - no inputs

hrtf_data - hrtf file.

SpatialMixer

public SpatialMixer(int bufferSize)

Create. For superclasses

Parameters:

bufferSize - Buffer size used for real-time rendering.

Method Detail

startHRTF

public void startHRTF()

set filename to obtain hrir info for 1 subject

Parameters:

filename - filename of subject's hrir data

stopHRTF

public void stopHRTF()

changeHRTF

public void changeHRTF(java.io.File filename)

setPosition

public void setPosition(int inputNo,
                        PositionData p)

set position of source

Parameters:

inputNo - buffer number to set position of

p - Position data gives the 3D coordinate of the sound source

computeBuffer

protected void computeBuffer()

Compute the next buffer and store in member float[] buf. Note if stereo then output buf[] is twice as big as input buffers --> this means that each source is a mono stream. will sourceContainer.size() always == n in Mixer constructor?

Specified by:

computeBuffer in class Out
