Class ESTTrackReader

java.lang.Object

marytts.util.data.ESTTrackReader

public class ESTTrackReader
extends Object

EST Track file reader This class interpretes a DataInputStream as an EST_Track file: it loads the whole track data in memory, and provides access methods to reach each individual frame or each individual track value.

Constructor Detail

ESTTrackReader

public ESTTrackReader(DataInputStream dis)

Constructor from an already open DataInputStream

Parameters:

dis - DataInputStream to read the EST_Track from

ESTTrackReader

public ESTTrackReader(String fileName)

Constructor from a file name

Parameters:

fileName - the name of the file to read the EST_Track from

Method Detail

getNumFrames

public int getNumFrames()

Get the number of frames in this track

Returns:

number of frames in this track

getNumChannels

public int getNumChannels()

Get the number of channels in this track

Returns:

number of channels in this track

getTimes

public float[] getTimes()

Get the times associated with this track

Returns:

an array of times associated with this track

getFrames

public float[][] getFrames()

Get the frames associated with this track

Returns:

an array of frames associated with this track

getTime

public float getTime(int index)

Get an individual time associated with this track

Parameters:

index - index of time to get

Returns:

time value at given index

isBigEndian

public boolean isBigEndian()

Returns the endianness of the file

Returns:

false if little endian (Intel), true if big endian (PowerPC, SPARC)

isBinary

public boolean isBinary()

Returns the mode of the file (ascii or binary)

Returns:

false if ascii text, true if binary

getClosestTime

public float getClosestTime(double seconds)

Get the frame time which is closest to a certain time specification. Time specifications falling after the last frame return the position of the last frame.

Parameters:

seconds - A time point, in seconds.

Returns:

(seconds - t1)<(t2 - seconds) ? t1:t2

getTimeSpan

public float getTimeSpan()

Get the time associated with the last frame

Returns:

time value of the last frame

getFrame

public float[] getFrame(int i)

Get an individual frame

Parameters:

i - index of frame

Returns:

the frame

getFrameEntry

public float getFrameEntry(int i,
                  int j)

Get an individual frame entry

Parameters:

i - index of frame

j - index into frame

Returns:

the frame entry in frame i at index j

getMinMax

public float[] getMinMax()

Get the max and the min over the whole file

Returns:

a vector of 2 float values in the order [min,max].

getMinMaxNo1st

public float[] getMinMaxNo1st()

Get the max and the min over the whole file, excluding the first column (which can be the energy in the EST LPCs)

Returns:

a vector of 2 float values in the order [min,max].
