Constructor Detail

OscillatorBank

public OscillatorBank(AudioContext context,
                      Buffer buffer,
                      int numOscillators)

Instantiates a new OscillatorBank.

Parameters:

context - the AudioContext.

buffer - the buffer used as a lookup table by the oscillators.

numOscillators - the number of oscillators.

Method Detail

setNumOscillators

public void setNumOscillators(int numOscillators)

Sets the number of oscillators.

Parameters:

numOscillators - the new number of oscillators.

setFrequenciesAndGains

public void setFrequenciesAndGains(float[][] freqsGains)

Sets the frequencies and gains of all oscillators from an array freqsGains[][] where freqsGains[i][0] gives the ith frequency, and freqsGains[i][1] gives the ith gain. This is the format generated by the SpectralPeaks FeatureExtractor.

Parameters:

freqsGains -

setFrequencies

public void setFrequencies(float[] frequencies)

Sets the frequencies of all oscillators.

Parameters:

frequencies - the new frequencies.

getFrequencies

public float[] getFrequencies()

Gets the array of frequencies.

Returns:

array of frequencies.

setGains

public void setGains(float[] gains)

Sets the gains of all oscillators.

Parameters:

gains - the new gains.

getGains

public float[] getGains()

Gets the array of gains.

Returns:

array of gains.

calculateBuffer

public void calculateBuffer()

Description copied from class: UGen

Called by the signal chain to update this UGen's ouput data. Subclassses of UGen should implement the UGen's DSP perform routine here. In general this involves grabbing data from UGen.bufIn and putting data into UGen.bufOut in some way. UGen.bufIn and UGen.bufOut are 2D arrays of floats of the form float[numChannels][bufferSize]. The length of the buffers is given by UGen.bufferSize, and the number of channels of the input and output buffers are given by UGen.ins and UGen.outs respectively.
