AudioSpectrogram()
Create a spectrogram that can be added to as and when it's necessary.
|
AudioSpectrogram(int w,
int h)
Construct a visualisation of the given size
|
| Modifier and Type | Method and Description |
|---|---|
void |
addListener(AudioSpectrogram.SpectrogramCompleteListener l)
Add the given listener
|
int |
getCurrentDrawPosition()
Get the position at which the next spectrum will be drawn.
|
Float[] |
getCurrentPositionLineColour()
Get the colour of the current position line
|
double[] |
getFrequencyBands()
Get the frequency bands which are being drawn in Hz.
|
boolean |
isComplete()
Returns whether the spectragram image is complete.
|
boolean |
isDrawCurrentPositionLine()
Returns whether the current position line is being drawn
|
boolean |
isDrawFreqBands()
Returns whether the frequency bands are being drawn.
|
void |
process(SampleChunk s)
Processes a single sample chunk: calculates the FFT, gets the magnitudes,
copies the format (if it's the first chunk), and then goes on to update the image.
|
void |
processStream(AudioStream as)
Process the entire stream (or as much data will fit into the
visualisation window).
|
void |
removeListener(AudioSpectrogram.SpectrogramCompleteListener l)
Remove the given listener
|
void |
setCurrentPositionLineColour(Float[] currentPositionLineColour)
Set the colour of the line which is showning the current draw position.
|
void |
setData(float[] data)
Set the data to be visualised.
|
void |
setData(SampleChunk sc)
Add the given sample chunk into the spectrogram.
|
void |
setDrawCurrentPositionLine(boolean drawCurrentPositionLine)
Set whether to draw the position at which the current spectra will be drawn
|
void |
setDrawFreqBands(boolean drawFreqBands)
Set whether to overlay the frequency bands onto the image.
|
void |
setFrequencyBands(double[] frequencyBands)
Set the frequency bands to overlay on the image in Hz.
|
void |
update()
Called to update the visualisation.

visImage member to be available and of the correct size.
The method simply needs to draw the visualisation to this MBFImage.
You should wrap any drawing code in a synchronized block, synchronized on
the visImage - this stops the image being repainted to the screen half way
through drawing.
Update is called from the paint() method so should ideally not force a repaint() as this will call a continuous repaint loop.
