Supported tuning systems and ratio tables.

Variants

EqualTemperament

Equal temperament with a configurable octave size.

Fields

octave_size: UnsignedIntegerType

Number of equal divisions in each octave.

WholeTone

Six-tone equal temperament.

QuarterTone

Twenty-four-tone equal temperament.

CarlosHarmonic

Twelve-tone harmonic-series scale (Wendy Carlos’s Harmonic).

Not just intonation, despite its former name: the degrees are the harmonic series 16:17:18:19:20:21:22:24:26:27:28:30, which reaches the 19-limit. TuningSystem::FiveLimit is the classical 12-tone JI scale.

CarlosHarmonic24

Twenty-four-tone harmonic-series scale.

PythagoreanTuning

Twelve-tone Pythagorean tuning table.

FiveLimit

Twelve-tone five-limit table.

ElevenLimit

Twenty-nine-tone eleven-limit table.

FortyThreeTone

Forty-three-tone ratio table.

Javanese

Five-tone Javanese equal-temperament approximation.

Thai

Seven-tone Thai equal-temperament approximation.

PtolemyIntenseDiatonic

Ptolemy’s intense diatonic, also Zarlino’s just major scale.

Greek and Renaissance European, despite once being filed here as an Indian scale — the archive names it ptolemy.scl.

IndianAlt

Alternate seven-tone PtolemyIntenseDiatonic scale table.

Indian22

Twenty-two-tone PtolemyIntenseDiatonic scale table.

QuarterCommaMeantone

Twelve-tone quarter-comma meantone temperament (Aaron, 1523).

WerckmeisterIII

Twelve-tone Werckmeister III well temperament (1681).

Rameau

Twelve-tone Rameau modified meantone temperament (1725).

KirnbergerIII

Twelve-tone Kirnberger III well temperament (1744).

Vallotti

Twelve-tone Vallotti well temperament (c. 1754).

YoungII

Twelve-tone Thomas Young well temperament no. 2 (1799).

ThirdCommaMeantone

A twelve-tone third-comma meantone temperament (Salinas, 1577).

SixthCommaMeantone

A twelve-tone sixth-comma meantone temperament (Salinas, 1577).

WerckmeisterIV

A twelve-tone Werckmeister IV well temperament (1681).

WerckmeisterV

A twelve-tone Werckmeister V well temperament (1681).

KirnbergerI

A twelve-tone Kirnberger I well temperament (1766).

NeidhardtI

A twelve-tone Neidhardt I well temperament (1724).

Silbermann

A twelve-tone Gottfried Silbermann temperament no. 1 (c. 1730).

LehmanBach

A twelve-tone Lehman-Bach temperament (2005).

Implementations

impl TuningSystem

pub fn id(self) -> &'static str

Returns the canonical identifier used by FromStr.

pub fn display_name(self) -> &'static str

Returns a compact display name for this tuning system.

pub fn description(self) -> &'static str

Returns a short description of this tuning system.

pub fn ratio(self, index: usize) -> FloatType

Returns the frequency ratio for a degree index.

pub fn fraction(self, index: usize) -> Fraction

Returns the table fraction for a degree index.

pub fn label(self, index: UnsignedIntegerType) -> String

Returns a display label for a degree index.

pub fn octave(self, index: UnsignedIntegerType) -> UnsignedIntegerType

Returns the octave number containing a degree index.

pub fn frequency(self, index: UnsignedIntegerType) -> FloatType

Returns the frequency in hertz for a degree index.

pub fn frequency_at(self, index: FloatType) -> FloatType

Returns the frequency in hertz for a fractional degree index.

pub fn cents(self, index: UnsignedIntegerType) -> FloatType

Returns cents offset from equal temperament for a degree index.

pub fn cents_at(self, index: FloatType) -> FloatType

Returns cents offset from equal temperament for a fractional degree index.

pub fn octave_size(self) -> UnsignedIntegerType

Returns the number of degrees in one octave for this tuning system.

Trait Implementations

impl Clone for TuningSystem

fn clone(&self) -> TuningSystem

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for TuningSystem

impl Debug for TuningSystem

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for TuningSystem

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for TuningSystem

impl From<TuningSystem> for AnyTuningSystem

fn from(tuning_system: TuningSystem) -> Self

Converts to this type from the input type.

impl FromStr for TuningSystem

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for TuningSystem

fn eq(&self, other: &TuningSystem) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
