Struct TuningTable 

pub struct TuningTable {
    pub frequencies: Vec<f32>,
    pub name: String,
    pub description: String,
}

Maps MIDI note numbers (0–127) to frequencies in Hz. Stored as Vec for serde compatibility.

Fields

frequencies: Vec<f32>

Frequency in Hz for each MIDI note 0–127.

name: String

Human-readable name.

description: String

Description of the tuning system.

Implementations

impl TuningTable

pub fn equal_temperament(concert_a: f32) -> Self

Standard 12-tone equal temperament. A4 (MIDI note 69) = concert_a Hz (typically 440.0).

pub fn from_cents_offsets(concert_a: f32, offsets: &[f32; 12]) -> Self

Build a tuning table from cents offsets per semitone within an octave. offsets is a 12-element array of cent offsets from 12-TET for each pitch class (C, C#, D, D#, E, F, F#, G, G#, A, A#, B).

pub fn from_frequencies( freqs: Vec<f32>, name: &str, description: &str, ) -> Option<Self>

Build from explicit frequency list. Length must be 128.

pub fn frequency(&self, note: u8) -> f32

Get frequency for a MIDI note number.

pub fn freq_to_note_cents(&self, freq: f32) -> (u8, f32)

Convert frequency to the nearest MIDI note + cents deviation.

pub fn ethiopian_tizita(concert_a: f32) -> Self

Ethiopian Kiñit (pentatonic) approximation. Uses the Tizita major scale pattern.

pub fn just_intonation(concert_a: f32) -> Self

Just intonation (pure intervals based on harmonic series).
