Constructor Detail

Interpolate

public Interpolate(int factor)

Increases the sample rate by a given factor.

Parameters:

factor - sample rate increase factor

Interpolate

public Interpolate()

Doubles the sample rate.

Interpolate

public Interpolate(float targetSampleRate)

Creates a interpolate processor that attempts to interpolate AudioBuffers to the specified target sample rate. Note that not all sample rates are supported. The ratio between sample rates should be an integer. If the target sample rate is not supported, an IOException is thrown when processing the first buffer.

Parameters:

targetSampleRate - target sample rate

Method Detail

getFactor

public int getFactor()

Returns:

sample rate factor or 0, if only a target sample rate was specified

See Also:

setFactor(int)

getTargetSampleRate

public float getTargetSampleRate()

Returns:

target sample rate or 0, if only a factor was set

setTargetSampleRate

public void setTargetSampleRate(float targetSampleRate)

Parameters:

targetSampleRate - target sample rate

setFactor

public void setFactor(int factor)

Increases the sample rate by the given factor.

Parameters:

factor - sample rate factor

Throws:

IllegalArgumentException - not all factors are supported

processNext

protected AudioBuffer processNext(AudioBuffer buffer)
                           throws IOException

Description copied from class: AbstractSignalProcessor

Processes the given input and returns some output.

Specified by:

processNext in class AbstractSignalProcessor<AudioBuffer,AudioBuffer>

Parameters:

buffer - input guaranteed not to be null.

Returns:

output produced by this processor

Throws:

IOException - if an IO error occurs

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
