AudioSpectrumFunctions.LogFrequencySpectrumToPitchDownsampling (beaTunes 5.2.24 API)

java.lang.Object
- com.tagtraum.audiokern.audioprocessor.AudioSpectrumFunctions.LogFrequencySpectrumToPitchDownsampling

All Implemented Interfaces:

MapFunction<LogFrequencySpectrum>

Enclosing class:

AudioSpectrumFunctions
```
public static class AudioSpectrumFunctions.LogFrequencySpectrumToPitchDownsampling
extends Object
implements MapFunction<LogFrequencySpectrum>
```
Effectively down-samples the bin resolution of a LogFrequencySpectrum to one bin per semitone by picking one of multiple bins and discarding the others.
The LogFrequencySpectrum.getBinsPerSemitone() of the source spectrum should contain an integer for this to work.

LogFrequencySpectrum.getBinsPerSemitone()
