final case class WPE_Dereverberate(in: D, fftSize: I = 512, winStep: I = 128, delay: I = 3, taps: I = 10, alpha: D = 0.9999, psdLen: I = 0) extends D with Product with Serializable
A graph element performing end-to-end blind de-reverberation of an input signal.
It performs the FFT/IFFT setup around invocations of WPE_ReverbFrame.
Note: this does not yet work correctly with multi-channel input.
- in
the reverberant time domain signal
- fftSize
the fft-size
- winStep
the step size for the sliding window; typically 1/4 of
fftSize- delay
the delay in spectral frames to avoid suppression of early reflections
- taps
the filter size in spectral frames to capture the late reverberation
- alpha
the decay factor for the filter coefficients
- psdLen
the number of preceding spectral frames to include as "context" in the psd
