Morse Code Translator with Audio - Morsify
Morsify is a Morse code encoder and decoder with no dependencies. Currently, it supports Latin, Cyrillic, Greek, Hebrew, Arabic, Persian, Japanese, Korean, and Thai, with audio-generation functionality using the Web Audio API.
$ npm install morsify --save
$ yarn add morsify
const morsify = require('morsify');
const encoded = morsify.encode('SOS'); // ... --- ...
const decoded = morsify.decode('... --- ...'); // SOS
const characters = morsify.characters(); // {'1': {'A': '.-', ...}, ..., '11': {'ㄱ': '.-..', ...}}
const audio = morsify.audio('SOS');
audio.play(); // play audio
audio.stop(); // stop audio
Alternatively, you can use the library directly with including the source file.
<script src="https://rawgit.com/ozdemirburak/morsify/master/dist/morsify.min.js"></script>
<script>
var encoded = morsify.encode('SOS'); // ... --- ...
var decoded = morsify.decode('... --- ...'); // SOS
var characters = morsify.characters(); // {'1': {'A': '.-', ...}, ..., '11': {'ㄱ': '.-..', ...}}
var audio = morsify.audio('SOS');
var oscillator = audio.oscillator; // OscillatorNode
var context = audio.context; // AudioContext
var gainNode = audio.gainNode; // GainNode
audio.play(); // play audio
audio.stop(); // stop audio
</script>
You can customize the dash, dot, or space characters and specify the alphabet with the priority option for an accurate encoding and decoding.
The priority option gives direction to the plugin to start searching for the given character set first.
Set the priority option according to the list below.
- 1 => ASCII (Default)
- 2 => Numbers
- 3 => Punctuation
- 4 => Latin Extended (Turkish, Polish etc.)
- 5 => Cyrillic
- 6 => Greek
- 7 => Hebrew
- 8 => Arabic
- 9 => Persian
- 10 => Japanese
- 11 => Korean
- 12 => Thai
const cyrillic = morsify.encode('Ленинград', { priority: 5 }); // .-.. . -. .. -. --. .-. .- -..
const greek = morsify.decode('... .- --. .- .--. .--', { priority: 6 }); // ΣΑΓΑΠΩ
const hebrew = morsify.decode('.. ––– . –––', { dash: '–', dot: '.', priority: 7 }); // יהוה
const japanese = morsify.encode('NEWS', { priority: 10, dash: '-', dot: '・', separator: ' ' }); // -・ ・ ・-- ・・・
const characters = morsify.characters({ dash: '–', dot: '•' }); // {'1': {'A': '•–', ...}, ..., '11': {'ㄱ': '•–••', ...}}
const arabicAudio = morsify.audio('البراق', { // generates the Morse .- .-.. -... .-. .- --.- then generates the audio from it
unit: 0.1, // period of one unit, in seconds, 1.2 / c where c is speed of transmission, in words per minute
oscillator: {
type: 'sine', // sine, square, sawtooth, triangle
frequency: 500, // value in hertz
onended: function () { // event that fires when the tone stops playing
console.log('ended');
}
}
});
const oscillator = arabicAudio.oscillator; // OscillatorNode
const context = arabicAudio.context; // AudioContext;
const gainNode = arabicAudio.gainNode; // GainNode
arabicAudio.play(); // will start playing Morse audio
arabicAudio.stop(); // will stop playing Morse audio
