Method Detail

allocate

public abstract void allocate(int numFrames,
                              int channelsPerFrame)

getRateScaler

public double getRateScaler(int index,
                            double synthesisRate)

Description copied from interface: SequentialData

Get rate to play the data. In an envelope this correspond to the inverse of the frame duration and would vary frame to frame. For an audio sample it is 1.0.

Specified by:

getRateScaler in interface SequentialData

Specified by:

getRateScaler in class SequentialDataCommon

Returns:

rate to scale the playback speed.

getFrameRate

public double getFrameRate()

setFrameRate

public void setFrameRate(double f)

getNumFrames

public int getNumFrames()

Specified by:

getNumFrames in interface SequentialData

Overrides:

getNumFrames in class SequentialDataCommon

Returns:

The number of valid frames that can be read.

getChannelsPerFrame

public int getChannelsPerFrame()

Specified by:

getChannelsPerFrame in interface SequentialData

Specified by:

getChannelsPerFrame in class SequentialDataCommon

Returns:

For a stereo sample, return 2.

setChannelsPerFrame

public void setChannelsPerFrame(int channelsPerFrame)

setPitch

public void setPitch(double pitch)

Set the recorded pitch as a fractional MIDI semitone value where 60 is Middle C.

Parameters:

pitch -

getPitch

public double getPitch()

getMarkerCount

public int getMarkerCount()

getMarker

public SampleMarker getMarker(int index)

addMarker

public void addMarker(SampleMarker marker)

Add a marker that will be stored sorted by position. This is normally used internally by the SampleLoader.

Parameters:

marker -
