Detailed Description

Runtime config class for plugin spec2wave, the counterpart of wave2spec.

Constructor & Destructor Documentation

spec2wave_t()

spec2wave_t::spec2wave_t	(	unsigned	nfft_,
		unsigned	nwnd_,
		unsigned	nwndshift_,
		unsigned	nch,
		mha_real_t	ramplen,
		const MHAWindow::base_t &	postwin
	)

Constructor.

Parameters

nfft_	FFT length.
nwnd_	Overlap-add analysis window length.
nwndshift_	Overlap-add hop size. Needed to compute scaling.
nch	Number of audio channels.
ramplen	A user-configurable factor which is applied to the length of the zero paddings in samples before and after the analysis window. Rising and falling hanning ramps are computed for the resulting ramp lengths in member ramps.
postwin	Post windowing function. This window is applied in addition to the hanning ramps. It is applied to the whole output waveform computed by the inverse FFT before the signal is overlap-added to the previous output.
