Detailed Description

Generate and hold bandlimited lookup tables for all the common waveforms.

Constructor & Destructor Documentation

BandLimitedLookupTables()

BandLimitedLookupTables::BandLimitedLookupTables	(	double	sampleRate = 44100,
		int	notesPerTable = 3,
		int	tableSize = 2048
	)

Member Function Documentation

setSampleRate()

void BandLimitedLookupTables::setSampleRate

(

double

sampleRate

)

reset()

void BandLimitedLookupTables::reset	(	double	sampleRate,
		int	notesPerTable = -1,
		int	tableSize = -1
	)

Rebuild the tables.

Does nothing if the parameters are unchanged, so it is safe to call from prepareToPlay. Pass -1 for notesPerTable or tableSize to keep the current value.

Building the tables is expensive; to defer the cost until the real sample rate is known, construct with a tiny table (e.g. notesPerTable 127, tableSize 1) then call reset later.
