Constructor Detail

AudioPanel

public AudioPanel(AudioData audioData,
                  float scaleX,
                  float scaleY)

Creates a new AudioPanel. The scale factors represent how much to scale the audio. A scaleX factor of 1.0f means one pixel per sample, and a scaleY factor of 1.0f means one pixel per resolution of the sample (e.g., a scale of 1.0f would take 2**16 pixels).

Parameters:

audioData - the AudioData to draw

scaleX - how much to scale the width of the audio

scaleY - how much to scale the height

Method Detail

setLabels

public void setLabels(float[] labelTimes,
                      java.lang.String[] labels)

Sets the labels to be used when drawing this panel.

Parameters:

labelTimes - label times

labels - labels

zoomSet

protected void zoomSet(float zoom)

Sets the zoom, adjusting the scroll bar in the process.

Parameters:

zoom - float zoom

paintComponent

public void paintComponent(java.awt.Graphics g)

Repaints the component with the given Graphics.

Overrides:

paintComponent in class javax.swing.JComponent

Parameters:

g - the Graphics to use to repaint the component.

getSelectionStart

public int getSelectionStart()

Returns the index of the sample representing the start of the selection. -1 means the very beginning.

Returns:

the start of the selection

See Also:

crop(), getSelectionEnd()

setSelectionStart

public void setSelectionStart(int newStart)

Sets the index of the sample of representing the start of the selection. -1 means the very beginning.

Parameters:

newStart - the new selection start

See Also:

crop(), setSelectionEnd(int)

getSelectionEnd

public int getSelectionEnd()

Returns the index of the sample representing the end of the selection. -1 means the very end.

Returns:

the end of the selection

See Also:

crop(), getSelectionStart()

setSelectionEnd

public void setSelectionEnd(int newEnd)

Sets the index of the sample of representing the end of the selection. -1 means the very end.

Parameters:

newEnd - the new selection end

See Also:

crop(), setSelectionStart(int)

crop

public void crop()

Crops the audio data between the start and end selections. All audio data outside the region will be permanently lost. The selection will be reset to the very beginning and very end of the cropped clip.
