com.tagtraum.audiokern.audioprocessor.LogFrequencyConcertPitch

All Implemented Interfaces:

SignalProcessor<LogFrequencySpectrum,LogFrequencySpectrum>

public class LogFrequencyConcertPitch
extends Object
implements SignalProcessor<LogFrequencySpectrum,LogFrequencySpectrum>

LogFrequencyConcertPitch

public LogFrequencyConcertPitch()

Method Detail

getMinReliability

public float getMinReliability()

Minimum reliability.

Returns:

minimim reliability

See Also:

setMinReliability(float)

setMinReliability

public void setMinReliability(float minReliability)

Sets the minimum reliability we need to actually shift processed spectra. I.e. if the reliability of the calculated tuning is too low, we do not shift downstream spectra

Parameters:

minReliability - minimum reliability

See Also:

DEFAULT_MIN_RELIABILITY

getReliability

public float getReliability()

Calculated strength of calculated tuning. Value between 0 and 1 - the higher the value the more confident we are in our tuning.

Returns:

strength

getCentDeviation()

connectTo

public <O2> SignalProcessor<LogFrequencySpectrum,O2> connectTo(SignalProcessor<LogFrequencySpectrum,O2> logFrequencySpectrumO2SignalProcessor)

Specified by:

connectTo in interface SignalProcessor<LogFrequencySpectrum,LogFrequencySpectrum>

process

public void process(LogFrequencySpectrum spectrum)
             throws IOException

Specified by:

process in interface SignalProcessor<LogFrequencySpectrum,LogFrequencySpectrum>

Throws:

IOException

flush

public void flush()
           throws IOException

Specified by:

flush in interface SignalProcessor<LogFrequencySpectrum,LogFrequencySpectrum>

Throws:

IOException

getCentDeviation

public Byte getCentDeviation()

Deviation of source spectra from concert pitch in cents. May return null, if we are not very confident in the tuning we calculated.

Returns:

deviation, maybe null

getOutput

public LogFrequencySpectrum getOutput()
                               throws IOException

Specified by:
