Detailed Description

TSF is the class implementing source-filter model for harmonic sinusoids. TSF shares the basic framework of the vibrato description class TVo, but implements a more compact source-filter representation. It does not go into detailed vibrato analysis such as extraction modulator shape.

An analysis/synthesis cycle converts THS to TSF and back.

Member Function Documentation

void TSF::AllocateL

(

int

AnL

)

method TSF::AllocateL: allocates or reallocates storage space whose size depends on L. This uses an external L value for allocation and updates L itself.

void TSF::AllocateP

(

)

method TSF::AllocateP: allocates or reallocates storage space whose size depends on P, using the interal P.

void TSF::AllocateSF

(

)

method TSF::AllocateSF: allocates or reallocates storage space for source-filter coefficients.

void TSF::Duplicate

(

TSF &

SF

)

method TSF::Duplicate: copies the complete contents from another SF object

In: SF: source object

void TSF::LoadFromFileHandle

(

FILE *

f

)

method TSF::LoadFromFileHandle: reads SF object from file

void TSF::LoadSFFromFileHandle

(

FILE *

f

)

method TSF::LoadSFFromFileHandle: reads SF coefficients from file

double TSF::LogAF

(

double

f

)

method TSF::LogAF: average filter response

In: f: frequency

Returns the average response of the filter model at f

double TSF::LogAF	(	double	f,
		int	fr
	)

method TSF::LogAF: filter response

In: f: frequency fr: frame index

Returns the response of the filter model at f for frame fr

double TSF::LogAS	(	int	m,
		int	fr
	)

method TSF::LogAS: source response

In: m: partial index fr: frame index

Returns response of the source model for partial m at frame fr

void TSF::ReAllocateL

(

int

newL

)

method TSF::ReAllocateL: reallocates storage space whose size depends on L, and transfer the contents. This uses an external L value for allocation but does not update L itself.

void TSF::SaveSFToFileHandle

(

FILE *

f

)

method TSF::SaveSFToFileHandle: writes SF coefficients to file

void TSF::SaveToFile

(

char *

filename

)

method TSF::SaveToFile: save SF object to file

In: filename: full path of destination file

void TSF::SaveToFileHandle

(

FILE *

f

)

method TSF::SaveToFileHandle: writes SF object to file

void TSF::ShiftFilterByDB

(

double

dB

)

method TSF::ShiftFilterByDB: adds a given number of dBs to the filter model.

In: dB: amount to add.
