Crate prime_osc 

prime-osc — Oscillators and envelopes.

All public functions are LOAD + COMPUTE. No STORE. No JUMP. State threads forward as an explicit parameter. Same inputs → same output.

Structs

AdsrParams

ADSR envelope parameters. All times in seconds.

AdsrState

ADSR envelope state. Thread forward with each call to adsr_step.

Enums

AdsrStage

ADSR envelope stage.

Functions

adsr_step

Advance ADSR envelope by one time step — pure LOAD + COMPUTE.

lfo_cosine

Cosine LFO. phase in [0, 1] maps to one full cycle.

lfo_sawtooth

Sawtooth wave at normalised phase (rising).

lfo_sine

Sine wave at normalised phase.

lfo_square

Square wave at normalised phase.

lfo_triangle

Triangle wave at normalised phase. Phase-aligned with lfo_sine (peak at 0.25).

osc_step

Advance oscillator phase by one sample and return (sample, new_phase).
