Constructor Detail

Mixer

public Mixer(int bufferSize,
             int n)

Create mono mixer

Parameters:

bufferSize - Buffer size used for real-time rendering.

n - no inputs

Mixer

public Mixer(int bufferSize,
             int n,
             int nChannels)

Create stereo mixer

Parameters:

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

n - no inputs

Mixer

public Mixer(int bufferSize)

Create. For superclasses

Parameters:

bufferSize - Buffer size used for real-time rendering.

Method Detail

setGain

public void setGain(int k,
                    float g)

Set input gain control vector.

Parameters:

k - index of gain

gains - input gain

setPan

public void setPan(int k,
                   float pan)

Set input pan

Parameters:

k - index of pan

pan - pan

setNChannels

public void setNChannels(int n)

Set nchannels

Parameters:

n - nchannels

getNChannels

public int getNChannels()

Get nchannels

Returns:

n nchannels

getGains

public float[] getGains()

Get input gain control vector.

Parameters:

gains - input gains

getPans

public float[] getPans()

Get input pan control vector.

Parameters:

gains - input gains

clear

public void clear()

Clear gains ato zero and pans to middle

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
