Syntax

class FConstantQAnalyzer

Remarks

FConstantQAnalyzer

The Constant Q Analyzer computs a pseudo constant q transform of the input audio. ConstantQ transforms produce frequency strength at logarithmically spaced frequency intervals (as opposed to the linearly spaced intervals of the FFT). Logarithmically spaced frequency intervals map nicely to musical scales.

Functions

		Name	Description
	void	CalculateCQT ( const float* InSamples, TArray< float >& OutCQT )	Calcualte Constant Q Transform of input audio.
	const FConst...	GetSettings()	Returns a reference to the settings used in this analyzer
