public class PamRawDataBlock
extends AcousticDataBlock<RawDataUnit>

Extension of RecyclingDataBlock that is used for Raw audio data.

Has the extra function for getting raw data samples out of the blocks. Also has some special constructors that set the parent and source data blocks to null. However, Raw data my be poduced by intermediate processes as well, in which case parent and source blocks will not be null

Constructor Detail

PamRawDataBlock

public PamRawDataBlock(java.lang.String name,
                       PamProcess parentProcess,
                       int channelMap,
                       float sampleRate)

PamRawDataBlock

protected PamRawDataBlock(java.lang.String name,
                          PamProcess parentProcess,
                          int channelMap,
                          float sampleRate,
                          boolean autoDisplay)

Method Detail

removeOldUnitsT

protected int removeOldUnitsT(long currentTimeMS)

Keep a record of the last sample added.

Overrides:

removeOldUnitsT in class PamDataBlock<RawDataUnit>

Parameters:

currentTimeMS - Time in milliseconds of the first data which must be kept

Returns:

the number of units removed

checkIntegrity

private boolean checkIntegrity()

Check the data block integrity - that is that all units are in order and that the sample numbers increase correctly.

Returns:

reportProblem

private void reportProblem(int nErrors,
                           int index,
                           java.lang.String str,
                           RawDataUnit unit)

getSamples

public double[][] getSamples(long startSample,
                             int duration,
                             int channelMap)

Creates an array and fills it with raw data samples.

Parameters:

startSample -

duration -

channelMap -

Returns:

double array of raw data

getSamples

public double[][] getSamples(long startSample,
                             int duration,
                             int channelMap,
                             double[][] wavData)

Gets samples of raw data into a pre existing array. If the array is the wrong size or does not exist, then a new one is created.

Parameters:

startSample -

duration -

channelMap -

wavData -

Returns:

double array of raw data

getTheSamples

private boolean getTheSamples(long startSample,
                              int duration,
                              int channelMap,
                              double[][] waveData)

Does the work for the above two functions.

Parameters:

startSample -

duration -

channelMap -

waveData -

Returns:

copies data into a double array, taking if from multiple raw datablocks if necessary

public ChannelListManager getChannelListManager()

Overrides:

getChannelListManager in class AcousticDataBlock<RawDataUnit>
