Basic waveforms that are used most often. A waveform function takes in a time varied frequency (in Hz).

Bipolar

osc :: Sig -> Sig

A pure tone (sine wave).

oscBy :: Tab -> Sig -> Sig

An oscillator with user provided waveform.

saw :: Sig -> Sig

A sawtooth.

isaw :: Sig -> Sig

Integrated sawtooth: 4 * x * (1 - x).

pulse :: Sig -> Sig

Pulse (not normalized).

sqr :: Sig -> Sig

A square wave.

tri :: Sig -> Sig

A triangle wave.

blosc :: Tab -> Sig -> Sig

A band-limited oscillator with user defined waveform (it's stored in the table).

Unipolar

unipolar :: Sig -> Sig

Turns a bipolar sound (ranges from -1 to 1) to unipolar (ranges from 0 to 1)

bipolar :: Sig -> Sig

Turns an unipolar sound (ranges from 0 to 1) to bipolar (ranges from -1 to 1)

on :: Sig -> Sig -> Sig -> Sig

Rescaling of the bipolar signal (-1, 1) -> (a, b)

on a b biSig

uon :: Sig -> Sig -> Sig -> Sig

Rescaling of the unipolar signal (0, 1) -> (a, b)

on a b uniSig

uosc :: Sig -> Sig

Unipolar pure tone.

uoscBy :: Tab -> Sig -> Sig
