Constructor Detail

ShortFrameSegmenter

public ShortFrameSegmenter(AudioContext context)

Instantiates a new ShortFrameSegmenter.

Parameters:

context - the AudioContext.

Method Detail

getChunkSize

public int getChunkSize()

Gets the chunk size.

Returns:

the chunk size.

setChunkSize

public void setChunkSize(int chunkSize)

Sets the chunk size.

Parameters:

chunkSize - the new chunk size.

getHopSize

public int getHopSize()

Gets the hop size.

Returns:

the hop size.

setHopSize

public void setHopSize(int hopSize)

Sets the hop size.

Parameters:

hopSize - the new hop size.

setWindow

public void setWindow(Buffer window)

Sets the window Buffer.

Parameters:

window - the new window Buffer.

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.

Specified by:

calculateBuffer in class UGen

resetTimeStamp

public void resetTimeStamp()

Description copied from class: AudioSegmenter

Reset both beginning and last time stamps to zero.

Specified by:

resetTimeStamp in class AudioSegmenter

setLastTimeStamp

public void setLastTimeStamp(TimeStamp ts)

Description copied from class: AudioSegmenter

Set the last TimeStamp of this AudioSegmenter. The next time a segment is produced, the start time of the segment will be this value. The counter is reset with this operation.

Specified by:

setLastTimeStamp in class AudioSegmenter

setBeginningTimeStamp

public void setBeginningTimeStamp(TimeStamp ts)

Description copied from class: AudioSegmenter

Set the TimeStamp of this AudioSegmenter when the AudioContext is at t=0.

Specified by:

setBeginningTimeStamp in class AudioSegmenter
