Oscillators with arbitrary but constant waveforms

static :: C a => T a b -> T a -> a -> T b Source

Oscillator with constant frequency. It causes aliasing effects for sharp waveforms and high frequencies.

staticAntiAlias :: C a => T a b -> T a -> a -> T b Source

Oscillator with constant frequency that suppresses aliasing effects using waveforms with controllable smoothness.

phaseMod :: C a => T a b -> a -> T a -> T b Source

oscillator with modulated phase

shapeMod :: C a => (c -> T a b) -> T a -> a -> T c -> T b Source

oscillator with modulated shape

freqMod :: C a => T a b -> T a -> T a -> T b Source

oscillator with modulated frequency

freqModAntiAlias :: C a => T a b -> T a -> T a -> T b Source

oscillator with modulated frequency

phaseFreqMod :: C a => T a b -> T a -> T a -> T b Source

oscillator with both phase and frequency modulation

shapeFreqMod :: C a => (c -> T a b) -> T a -> T c -> T a -> T b Source

oscillator with both shape and frequency modulation

staticSample :: C a => T a b -> T b -> T a -> a -> T b Source

oscillator with a sampled waveform with constant frequency This essentially an interpolation with cyclic padding.

freqModSample :: C a => T a b -> T b -> T a -> T a -> T b Source

oscillator with a sampled waveform with modulated frequency Should behave homogenously for different types of interpolation.

shapeFreqModSample :: (C c, C a) => T c (T a b) -> T (T a b) -> c -> T a -> T c -> T a -> T b Source
