Frequency is a primitive type for encoding Frequency values.
Eventually all time values are evaluated to hertz using the eval method.
import { Frequency } from "tone";
Frequency("C3"); // 261
Frequency(38, "midi");
Frequency("C3").transpose(4);The context associated with the time value. Used to computeTransport and context-relative timing.
The concert tuning pitch which is used to generate all the other pitch values from notes. A4's values in Hertz.
Set this debug flag to log all events that happen in this class.
Indicates if the instance was disposed. 'Disposing' an instance means that all of the Web Audio nodes that were created for the instance are disconnected and freed for garbage collection.
The version number semver
disconnect and dispose.
Coerce a time type into this units type.
Returns all of the default options belonging to the class.
Takes an array of semitone intervals and returns an array of frequencies transposed by those intervals.
import { Frequency } from "tone";
Frequency("A4").harmonize([0, 3, 7]); // ["A4", "C5", "E5"]
Quantize the time by the given subdivision. Optionally add a percentage which will move the time value towards the ideal quantized value by that percentage.
import { Time } from "tone";
Time(21).quantize(2); // returns 22
Time(0.6).quantize("4n", 0.5); // returns 0.55
Move the time value towards the quantized value by a percentage.
Return the time encoded as Bars:Beats:Sixteenths.
Return the value in hertz
Return the value of the frequency as a MIDI note
import { Frequency } from "tone";
Frequency("C4").toMidi(); // 60
Return the time in milliseconds.
Convert a Time to Notation. The notation values are will be the closest representation between 1m to 128th note.
import { Time } from "tone";
// if the Transport is at 120bpm:
Time(2).toNotation(); // returns "1m"
Return the value of the frequency in Scientific Pitch Notation
import { Frequency } from "tone";
Frequency(69, "midi").toNote(); // "A4"
Return the time in samples
Convert the class to a string
import { Oscillator } from "tone";
const osc = new Oscillator();
console.log(osc.toString());
Transposes the frequency by the given number of semitones.
import { Frequency } from "tone";
Frequency("A4").transpose(3); // "C5"
Evaluate the time value. Returns the time in seconds.
