Method Detail

createMapFunction

public static <T extends AudioBuffer> MapFunction<T> createMapFunction(MapFunction<float[]> function)

Creates an AudioBuffer map function that maps both the real and the imaginary part of the buffer using the provided float[] map function.

Type Parameters:

T - actual type of the resulting map function

Parameters:

function - float[] map function

Returns:

map function typed to process audio buffers

createMagnitudeMapFunction

public static <T extends AudioBuffer> MapFunction<T> createMagnitudeMapFunction(MapFunction<float[]> function)

Creates an AudioBuffer map function that maps the magnitudes of the buffer using the provided float[] map function. This implies that the imaginary part of the data becomes null.

Type Parameters:

T - actual type of the resulting map function

Parameters:

function - float[] map function

Returns:

map function typed to process audio buffers

createPowerMapFunction

public static <T extends AudioBuffer> MapFunction<T> createPowerMapFunction(MapFunction<float[]> function)

Creates an AudioBuffer map function that maps the powers of the buffer using the provided float[] map function. This implies that the imaginary part of the data becomes null. After the given function has been applied to the powers, the square root is set as the new real part of the data.

Type Parameters:

T - actual type of the resulting map function

Parameters:

function - float[] map function

Returns:

map function typed to process audio buffers

createStatefulMapFunction

public static <T extends AudioBuffer> StatefulMapFunction<T> createStatefulMapFunction(StatefulMapFunction<float[]> function)

Creates a AudioBuffer stateful map function that maps both the real and the imaginary part of the buffer using the provided float[] map function.

Type Parameters:

T - actual type of the resulting map function

Parameters:

function - float[] map function

Returns:

map function typed to process audio buffers

createDistanceFunction

public static <T extends AudioBuffer> DistanceFunction<T> createDistanceFunction(DistanceFunction<float[]> function)

Creates an AudioBuffer distance function that computes the distance between the data (as in AudioBuffer.getData()) of two buffers using the provided float[] distance function.

Type Parameters:

T - actual type of the resulting distance function

Parameters:

function - float[] distance function

Returns:

distance function typed to process audio buffers

createPowerDistanceFunction

public static <T extends AudioBuffer> DistanceFunction<T> createPowerDistanceFunction(DistanceFunction<float[]> function)

Creates an AudioBuffer distance function that computes the distance between the data (as in AudioBuffer.getPowers()) of two buffers using the provided float[] distance function.

Type Parameters:

T - actual type of the resulting distance function

Parameters:

function - float[] distance function

Returns:

distance function typed to process audio buffers

createAggregateFunction

public static <T extends AudioBuffer> AggregateFunction<T,Float> createAggregateFunction(AggregateFunction<float[],Float> function)

Creates an AudioBuffer aggregate function that computes a Float for the buffers using the provided float[] aggregate function.

Type Parameters:

T - actual type of the resulting aggregate function

Parameters:

function - float[] aggregate function

Returns:

aggregate function typed to process audio buffers
