Crate sim_lib_sound_core 

Core sound primitives for the SIM music constellation.

This crate defines the foundational acoustic types shared by the sound/synthesis layer: Frequency, Amplitude, and Phase quantities; the Partial, Envelope, and Tone models that build a spectral tone from sinusoidal components; and helpers for default envelopes and equal-temperament pitch-to-frequency conversion.

Structs

Amplitude

A non-negative linear amplitude.

Envelope

An attack/decay/sustain/release amplitude envelope.

Frequency

A positive frequency in hertz.

Partial

A single sinusoidal component of a tone.

Phase

A phase angle in radians.

Tone

A complete tone: a set of Partials shaped by an Envelope over a fixed duration.

Enums

EnvelopeShape

The interpolation curve applied across an Envelope.

SoundCoreError

Error raised when sound primitives are constructed with invalid values.

Statics

RECIPES

Cookbook recipes for this lib, embedded at build time.

Functions

default_envelope

Returns a general-purpose default envelope (short attack and decay, high sustain, moderate release, linear shape).

equal_temperament_frequency

Returns the 12-tone equal-temperament frequency of pitch, with A4 (MIDI 69) anchored at 440 Hz.
