Detailed Description

This abstract class defines the interface for classes that implement all types of signal domain processing supported by the MHA: wave2wave, spec2spec, wave2spec, and spec2wave.

For supporting different output domains for the same input domain, the processing methods are overloaded with respect to input domain and output domain.

Constructor & Destructor Documentation

◆ ~fourway_processor_t()

virtual PluginLoader::fourway_processor_t::~fourway_processor_t ( )

inlinevirtual

Classes with virtual methods need virtual destructor.

This destructor is empty.

Member Function Documentation

◆ process() [1/4]

virtual void PluginLoader::fourway_processor_t::process	(	mha_wave_t *	s_in,
		mha_wave_t **	s_out
	)

pure virtual

Pure waveform processing.

Parameters

s_in	input waveform signal
s_out	output waveform signal

Implemented in PluginLoader::mhapluginloader_t.

◆ process() [2/4]

virtual void PluginLoader::fourway_processor_t::process	(	mha_spec_t *	s_in,
		mha_spec_t **	s_out
	)

pure virtual

Pure spectrum processing.

Parameters

s_in	input spectrum signal
s_out	output spectrum signal

Implemented in PluginLoader::mhapluginloader_t.

◆ process() [3/4]

virtual void PluginLoader::fourway_processor_t::process	(	mha_wave_t *	s_in,
		mha_spec_t **	s_out
	)

pure virtual

Signal processing with domain transformation from waveform to spectrum.

Parameters

s_in	input waveform signal
s_out	output spectrum signal

Implemented in PluginLoader::mhapluginloader_t.

◆ process() [4/4]

virtual void PluginLoader::fourway_processor_t::process	(	mha_spec_t *	s_in,
		mha_wave_t **	s_out
	)

pure virtual

Signal processing with domain transformation from spectrum to waveform.

Parameters

s_in	input spectrum signal
s_out	output waveform signal

Implemented in PluginLoader::mhapluginloader_t.

◆ prepare()

virtual void PluginLoader::fourway_processor_t::prepare ( mhaconfig_t & settings )

pure virtual

Prepares the processor for signal processing.

Parameters

settings domain and dimensions of the signal. The contents of settings may be modified by the prepare implementation. Upon calling fourway_processor_t::prepare, settings reflects domain and dimensions of the input signal. When fourway_processor_t::prepare returns, settings reflects domain and dimensions of the output signal.

Implemented in plug_t, mhaplug_cfg_t, and PluginLoader::mhapluginloader_t.
