static float	freqToLen (float f)
	This method converts frequency to wavelength. The oscillate function takes wavelength as argument so use this to convert your note frequency to wavelength before using it.
static float	freqToLen (float f, sample_rate_t sr)
	This method converts frequency to wavelength, but you can use any custom sample rate with it.
static float	pdToLen (float pd)
	This method converts phase delta to wavelength. It assumes a phase scale of 0 to 1.
static sample_t	oscillate (float _ph, float _wavelen, Waveform _wave)
	This method provides interpolated samples of bandlimited waveforms.

Member Function Documentation

freqToLen() [1/2]

float lmms::BandLimitedWave::freqToLen ( float f )

inlinestatic

This method converts frequency to wavelength. The oscillate function takes wavelength as argument so use this to convert your note frequency to wavelength before using it.

freqToLen() [2/2]

float lmms::BandLimitedWave::freqToLen ( float f, sample_rate_t sr )

inlinestatic

This method converts frequency to wavelength, but you can use any custom sample rate with it.

generateWaves()

void lmms::BandLimitedWave::generateWaves ( )

static

oscillate()

sample_t lmms::BandLimitedWave::oscillate ( float _ph, float _wavelen, Waveform _wave )

inlinestatic

This method provides interpolated samples of bandlimited waveforms.

Parameters

_ph	The phase of the sample.
_wavelen	The wavelength (length of one cycle, ie. the inverse of frequency) of the wanted oscillation, measured in sample frames
_wave	The wanted waveform. Options currently are saw, triangle, square and moog saw.

pdToLen()

float lmms::BandLimitedWave::pdToLen ( float pd )

inlinestatic

This method converts phase delta to wavelength. It assumes a phase scale of 0 to 1.
