About Morse Code
Morse code is a method used in telecommunication to encode text characters as standardized sequences of two different signal durations, called dots and dashes.

Standard Separators:
Dot (.): 1 unit of time.
Dash (-): 3 units of time.
Space between symbols: 1 unit of time.
Space between letters: 3 units of time.
Space between words (/): 7 units of time.

Interactive Morse Code Translator with Sound

Morse Code is a legendary communication system that represents text as standardized sequences of two different signal durations: Dots (.) and Dashes (-). From its invention in the 1830s for telegraphy to its vital role in modern aviation and maritime distress, Morse code remains a fascinating and useful skill.

Our Online Morse Code Encoder/Decoder provides an interactive way to learn, translate, and hear Morse code signals.

Professional Features

1. Accurate Translation

Encode any alphanumeric string (A-Z, 0-9) and common punctuation marks into their international Morse code equivalents. Our decoder also handles strings of dots and dashes, turning them back into readable English.

2. Built-in Audio Oscillator

Click the "Play Sound" button to hear your message as an audio signal. We use a precise 600Hz sine wave oscillator to simulate real radio telegraphy.

  • Dot: Short beep (100ms).
  • Dash: Long beep (300ms).

3. Visual Formatting

We use standard separators to ensure clarity:

  • Spaces separate individual letters.
  • Forward Slashes (/) separate words.

Practical Uses for Morse Code Today

  1. Amateur Radio (Ham): Still popular among hobbyists for long-distance low-power communication.
  2. Survival/Emergency: A vital survival skill; the SOS signal (... --- ...) is recognized globally.
  3. Aviation/Maritime: Used for identifying navigation beacons and in some distress scenarios.
  4. Education & Play: A fun way for kids and hobbyists to understand the basics of digital communication.
  5. Escape Rooms: Frequently used as a method for encoding clues or puzzles.

Frequently Asked Questions

What does "SOS" mean in Morse code?

Contrary to popular belief, SOS doesn't mean "Save Our Ships" or "Save Our Souls". It was chosen because it's a unique, easy-to-remember sequence (... --- ...) that stands out clearly in noisy radio signals.

How do I write Morse code in this tool?

Use a periods (.) for dots, hyphens (-) for dashes, and spaces to separate characters. Use a / or multiple spaces to separate words.

Can this tool translate emojis?

No, standard Morse code is limited to the Latin alphabet, numbers, and basic punctuation. For Emojis, we recommend our Unicode Encoder.
