Method Details

reset

public void reset(double inputSampleRate,
 int channelMap)

Description copied from interface: PlaybackPreprocess

Reset or prepare the process
Will almost definitely need another less abstract process for setting more specific task parameters.

Specified by:

reset in interface PlaybackPreprocess

Parameters:

channelMap - map of channels that are going to get processed.

processDataUnit

public RawDataUnit processDataUnit(RawDataUnit inputDataUnit,
 boolean mustCopy)

Description copied from interface: PlaybackPreprocess

Process a data unit.

Specified by:

processDataUnit in interface PlaybackPreprocess

Parameters:

inputDataUnit - source data unit.

mustCopy - data must not be modified in place. This will be set true for the rist unit in a chain in the playback system (generally a decimator) after that it will be false meaning that processes are free to modify the data in place so long as it remains consistent in length, etc.

Returns:

a Raw data unit which may or may not be the same as the input one.
