Member Function Documentation

◆ process()

mha_spec_t * smooth_cepstrum::smooth_cepstrum_if_t::process ( mha_spec_t * signal )

This plugin implements noise reduction using spectral subtraction: by nonnegative subtraction from the output magnitude of the estimated noise magnitude spectrum.

Parameters

signal Pointer to the input signal structure.

Returns: Returns a pointer to the input signal structure, with a the signal modified by this plugin.

◆ prepare()

void smooth_cepstrum::smooth_cepstrum_if_t::prepare ( mhaconfig_t & signal_info )

virtual

Plugin preparation.

This plugin checks that the input signal has the spectral domain and contains at least one channel

Parameters

signal_info Structure containing a description of the form of the signal (domain, number of channels, frames per block, sampling rate.

Implements MHAPlugin::plugin_t< smooth_cepstrum_t >.
