Detailed Description

TVo is the data structure hosting descriptors of a vibrato representation of a harmonic sinusoid. Its basic framework is shared by the TSF object which hosts a more elaborate source-filter model than TVo, but does not look into vibrato-specific features such as modulator shape.

An analysis/sythesis cycle converts THS to TVo and back.

Member Function Documentation

void TVo::AllocateL

(

int

AnL

)

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

void TVo::AllocateP

(

)

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

void TVo::AllocatePK

(

)

method TVo::AllocatePK: allocates or reallocates storage space whose size depends on both P and K.

double TVo::GetOldP

(

)

method TVo::GetOldP: returns the number of "equivalent" cycles of the whole duration. Although P-1 cycles are delineated by lp[P], the parts before lp[0] and after lp[P-1] are also a part of the harmonic sinusoid being modeled and therefore should be taken into account when necessary.

void TVo::LoadFromFileHandle

(

FILE *

file

)

methodTVo::LoadFromFileHandle: reads TVo object from a file stream.

void TVo::ReAllocateL

(

int

newL

)

method TVo::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 TVo::SaveToFile

(

char *

filename

)

method TVo::SaveToFile: saves a TVo object to a file.

In: filename: path to the destination file.

void TVo::SaveToFileHandle

(

FILE *

file

)

method TVo::SaveToFileHandle: saves a TVo object to an open file stream.
