Inheritance diagram for CLAM::SinusoidalSynthesis:

Detailed Description

This is a processing object class that performs a sinusoidal resynthesis given a set of spectral peaks.

Because it performs only one IFFT rather than the three performed by SMSSynthesis and it does not have process the residual, it requires approximately half the CPU cycles needed by SMSSynthesis, and it uses a lot less memory.

Member Function Documentation

const char* CLAM::SinusoidalSynthesis::GetClassName ( ) const [inline, virtual]

Override it in every subclass and retur the name of that class.

Reimplemented from CLAM::ProcessingComposite.

Definition at line 103 of file SinusoidalSynthesis.hxx.

const ProcessingConfig& CLAM::SinusoidalSynthesis::GetConfig ( ) const [inline, virtual]

Configuration getter.

Gets the configuration parameters used to create the object.

Returns:: Const reference to the configuration object. The usual way to perform a configuration change in the processing object is to take a copy of this reference, to change it and to send it with the Configure method. If not overriden, it returns a NullProcessingConfig.

Implements CLAM::ProcessingComposite.

Definition at line 106 of file SinusoidalSynthesis.hxx.

bool CLAM::SinusoidalSynthesis::Do ( void ) [virtual]

Supervised mode execution.

Implements CLAM::ProcessingComposite.

bool CLAM::SinusoidalSynthesis::Do	(	SpectralPeakArray &	inputSinusoidalPeaks,
		Spectrum &	outputSpectrum,
		Audio &	outputAudio
	)

non-supervised Do method.

Produces as output the sinusoidal spectrum, the global spectrum. and the sinusoidal, residual and globar audio frames. If this overload is used directly you must set the controls for current time and current pitch from the outside.

bool CLAM::SinusoidalSynthesis::Do	(	SpectralPeakArray &	inputSinusoidal,
		Audio &	outputAudio
	)

non-supervised Do method.

SinusoidalSynthesis produces, as side effect, also some output Spectrums. Use this overload if you do not care about these spectrums and just need the output audio. If this overload is used directly you must set the controls for current time and current pitch from the outside.

bool CLAM::SinusoidalSynthesis::Do ( Segment & in )

non-supervised Do method: works on a CLAM::Segment.

Processes current frame in the segment and increments segment internal counter.
