Morse Code Translator

Common Use Cases for Morse Translation

• ✓
  Amateur Radio (Ham)

  Encode messages for transmission or practice CW (continuous wave) operations efficiently.

• ✓
  Educational Purposes

  Teach Morse code in classrooms or self-study with visual/audio aids for beginners.

• ✓
  Puzzles and Games

  Create or solve cryptic challenges, escape rooms, or trivia involving code translation.

• ✓
  Emergency Communication

  Prepare backup signaling for survival kits or off-grid scenarios where voice fails.

• ✓
  Creative Projects

  Incorporate Morse into art, music, or apps for unique, retro-inspired effects.

• ✓
  Security and Ciphers

  Layer with other encryptions for fun steganography or message obfuscation.

Why Choose Our Translator?

How to Use the Morse Code Translator

1. Enter Input: Type text (e.g., "HELLO") or Morse (e.g., ".... . .-.. .-.. ---") in the field
2. Select Mode: Auto-detect or toggle text-to-Morse/decode; adjust WPM and tone
3. Preview Output: See encoded Morse; play audio to hear dots/dashes sequence
4. Refine Settings: Tune speed for practice; handle case-insensitivity automatically
5. Export Results: Copy text, download WAV audio, or save for reference

Understanding Morse Code Translation

Morse maps characters to dot-dash patterns: A=.-, B=-...; encoding splits text into letters, joins with spaces, words with /. Decoding parses sequences using a lookup table. Audio generates tones (dot=short high, dash=long high) with silence gaps based on WPM—where 1 WPM = 12 words (50 chars) per minute.

Example: "SOS" → "... --- ..." (distress signal); audio: three short, three long, three short beeps.

• Decoding: Split by space, reverse map; handle ambiguities with context
• Audio Synthesis: Oscillator for 800Hz tone; dot=1 unit, dash=3, letter space=3, word=7

Uses object lookups for speed; Web Audio for playback without plugins.

Privacy & Usage Considerations

This translator offers secure, offline Morse handling:

• Local Execution: No inputs sent; ideal for private or sensitive transmissions
• Practice Tips: Start slow (10 WPM); use headphones for clear audio in noisy environments
• Best Practices: Verify with official charts; combine with Text Case Converter for prep
• Limitations: Basic Latin only; for full Unicode, extend mappings

Integration & Code Examples

Implement Morse translation in JavaScript with mappings and audio:

// Morse code mapping
const morseCode = {
  'A': '.-', 'B': '-...', 'C': '-.-.', // ... full alphabet
  ' ': '/'
};

// Function to encode text to Morse
function textToMorse(text) {
  return text.toUpperCase().split('').map(char => 
    morseCode[char] || char
  ).join(' ');
}

// Function to decode Morse to text
function morseToText(morse) {
  const words = morse.split(' / ');
  return words.map(word => 
    word.split(' ').map(code => 
      Object.keys(morseCode).find(key => morseCode[key] === code) || code
    ).join('')
  ).join(' ');
}

// Example usage
console.log(textToMorse('HELLO')); // '.... . .-.. .-.. ---'
console.log(morseToText('.... . .-.. .-.. ---')); // 'HELLO'

// Simple audio (requires Web Audio API)
function playMorse(code, freq = 800, wpm = 20) {
  const audioCtx = new (window.AudioContext || window.webkitAudioContext)();
  const unit = 1200 / wpm; // ms per unit
  code.split(' ').forEach((seq, i) => {
    setTimeout(() => {
      seq.split('').forEach((dotDash, j) => {
        const duration = dotDash === '.' ? unit : 3 * unit;
        const osc = audioCtx.createOscillator();
        osc.connect(audioCtx.destination);
        osc.frequency.value = freq;
        osc.start(audioCtx.currentTime + j * unit + i * 7 * unit);
        osc.stop(audioCtx.currentTime + duration / 1000 + j * unit + i * 7 * unit);
      });
    }, i * 7 * unit);
  });
}
