Member Function Documentation

bool CLAM::FFT_numrec::Do

(

)

[virtual]

Supervised-mode Do function.

Implements CLAM::FFT_base.

bool CLAM::FFT_numrec::Do	(	const Audio &	in,
		Spectrum &	out
	)		[virtual]

Standard FFT Do function, with storage class references as arguments.

This method implements the old conversor routines. The resulting spectrum will be of input audio size / 2 + 1. Input audio must be a power-of-two.

Implements CLAM::FFT_base.

const char* CLAM::FFT_numrec::GetClassName

(

)

const [inline, virtual]

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

Implements CLAM::Processing.

Definition at line 64 of file FFT_numrec.hxx.

bool CLAM::FFT_numrec::MayDisableExecution

(

)

const [inline, virtual]

Reimplemented from CLAM::FFT_base.

Definition at line 74 of file FFT_numrec.hxx.
