generateSound

public QASound generateSound(long sourceSample,
 double sampleRate,
 double[] delays,
 double[] amplitudes)

Description copied from class: QASoundGenerator

Generate a sound

Specified by:

generateSound in class QASoundGenerator

Parameters:

sourceSample - the sample number at which the source was generated

sampleRate - sample rate of data to receive the sound

delays - delays in samples from generation of the sound to it's reception on each hydrophone

amplitudes - amplitudes on a linear scale (notDB) which incorporates the system full scale and the spreading loss but doesn't yet contain frequency dependent attenuation.

Returns:

a generated sound.

makeWave

public final double[] makeWave(double sampleRate,
 double sampleOffset,
 double amplitude)

Parameters:

sampleOffset - actual time of first sample - between 0 and 1

amplitude - amplitude multiplier.

Returns:

waveform for a single channel

makePhase

protected double[] makePhase(double sampleRate,
 double sampleOffset,
 double amplitude)

getStandardSoundParams

public StandardSoundParams getStandardSoundParams()

Returns:

the standardSoundParams

setStandardSoundParams

public void setStandardSoundParams(StandardSoundParams standardSoundParams)

Parameters:

standardSoundParams - the standardSoundParams to set

getSoundWindow

public SoundWindow getSoundWindow()

Returns:

the soundWindow

setSoundWindow

public void setSoundWindow(SoundWindow soundWindow)

Parameters:

soundWindow - the soundWindow to set

getHarmonics

public double[] getHarmonics()

Returns:

the harmonics

setHarmonics

public void setHarmonics(double[] harmonics)

Parameters:

harmonics - the harmonics to set

getFrequencyRange

public double[] getFrequencyRange()

Specified by:

getFrequencyRange in class QASoundGenerator

Returns:

The nominal frequency range of the sound in Hz.

getDurationRange

public double[] getDurationRange()

Specified by:

getDurationRange in class QASoundGenerator

Returns:

the nominal duration of the sound in seconds.
