Method Detail

getName

public String getName()

Specified by:

getName in interface PraatTier

getXmax

public double getXmax()

Specified by:

getXmax in interface PraatTier

setXmax

public void setXmax(double value)

getXmin

public double getXmin()

Specified by:

getXmin in interface PraatTier

setXmin

writeTo

public void writeTo(Writer out)

toFrames

public double[] toFrames(double step)

Convert this sequence of pitch targets into an array of frame values. Values before the first target are NaN, values after the last target are NaN; values between targets are linearly interpolated.

Parameters:

step - the constant time distance between two frames, in seconds.

Returns:

an array of doubles representing the equally spaced frequency values, from xmin to xmax.

getFrequency

public double getFrequency(double time)

importFrames

protected void importFrames(double[] frames,
                            double step)

For every frame that is not NaN, create a pitch-time target.

Parameters:

frames - frames

step - step

equals

public boolean equals(Object otherObj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
