getBandCount

back to summary

public int getBandCount()

Gets the number of bands in the audio spectrum

Returns:int: int value

getEnabled	back to summary
public boolean getEnabled() Returns whether audio spectrum is enabled or not. Returns:boolean boolean value

getEnabled

back to summary

public boolean getEnabled()

Returns whether audio spectrum is enabled or not.

Returns:boolean: boolean value

getInterval back to summary

getInterval	back to summary
public double getInterval() Returns the interval between `AudioSpectrumEvents in seconds.` `Returns:double double value`

public double getInterval()

Returns the interval between AudioSpectrumEvents in seconds.

Returns:double: double value

getMagnitudes back to summary

getMagnitudes	back to summary
public float[] getMagnitudes(float[] magnitudes) Returns an array of the last available magnitudes. The size of the array equals the number of bands set by the `setBandCount(int)` method. A newly created array contains `Float.NEGATIVE_INFINITY` values. When the number of bands is 0 this method returns an empty array. If a non-null array large enough to hold the values is passed in, it will be used; otherwise a newly allocated array will be returned. Parameters magnitudes:float[] An optionally preallocated double array. Returns:float[] array of float values.

public float[] getMagnitudes(float[] magnitudes)

Returns an array of the last available magnitudes. The size of the array equals the number of bands set by the setBandCount(int) method. A newly created array contains Float.NEGATIVE_INFINITY values. When the number of bands is 0 this method returns an empty array. If a non-null array large enough to hold the values is passed in, it will be used; otherwise a newly allocated array will be returned.

Parameters

magnitudes:float[]: An optionally preallocated double array.

Returns:float[]

array of float values.

getPhases back to summary

getPhases	back to summary
public float[] getPhases(float[] phases) Returns an array of the last available phases. The size of the array equals the number of bands set by the `setBandCount(int)` method. A newly created array contains 0.0 values. When the number of bands is 0 this method returns an empty array. If a non-null array large enough to hold the values is passed in, it will be used; otherwise a newly allocated array will be returned. Parameters phases:float[] An optionally preallocated double array. Returns:float[] array of float values.

public float[] getPhases(float[] phases)

Returns an array of the last available phases. The size of the array equals the number of bands set by the setBandCount(int) method. A newly created array contains 0.0 values. When the number of bands is 0 this method returns an empty array. If a non-null array large enough to hold the values is passed in, it will be used; otherwise a newly allocated array will be returned.

Parameters

phases:float[]: An optionally preallocated double array.

Returns:float[]

array of float values.

getSensitivityThreshold	back to summary
public int getSensitivityThreshold() Returns sensitivity threshold in dB. All lower values will be set to this. Returns:int int value

getSensitivityThreshold

back to summary

public int getSensitivityThreshold()

public void setInterval(double interval) Set the interval between `AudioSpectrumEvents in seconds.` `Parameters interval:double double value`

public void setInterval(double interval)

Set the interval between AudioSpectrumEvents in seconds.

Parameters: interval:double
