EZAudioFFTDelegate

@protocol EZAudioFFTDelegate <NSObject>

The EZAudioFFTDelegate provides event callbacks for the EZAudioFFT (and subclasses such as the EZAudioFFTRolling) whenvever the FFT is computed.

Getting FFT Output Data


                    
                    
                    -fft:updatedWithFFTData:bufferSize:

Triggered when the EZAudioFFT computes an FFT from a buffer of input data. Provides an array of float data representing the computed FFT. - parameter: fft The EZAudioFFT instance that triggered the event. - parameter: fftData A float pointer representing the float array of FFT data. - parameter: bufferSize A vDSP_Length (unsigned long) representing the length of the float array.

Declaration

Objective-C

- (void)fft:(EZAudioFFT *)fft
    updatedWithFFTData:(float *)fftData
            bufferSize:(vDSP_Length)bufferSize;

Swift

optional func fft(_ fft: EZAudioFFT!, updatedWithFFTData fftData: UnsafeMutablePointer

Parameters

`fft`	The EZAudioFFT instance that triggered the event.
`fftData`	A float pointer representing the float array of FFT data.
`bufferSize`	A vDSP_Length (unsigned long) representing the length of the float array.
