À propos de cet outil

Morse code represents every letter and digit as a sequence of short and long signals - dots and dashes - originally designed for telegraph operators to send over a single wire, and later adopted for radio, light signalling (like a ship's signal lamp) and the SOS distress call. This tool translates in both directions and, unlike a plain text-to-Morse converter, can actually PLAY the result back - as an audible tone with correct timing, or as a full-screen light flash - which is closer to how Morse is really used than reading dots and dashes off a screen.

Comment utiliser cet outil

  1. Choose a directionText to Morse, or Morse to Text.
  2. Type or pasteFor Morse input, separate letters with a space and words with a slash ( / ).
  3. Play it backFor Text to Morse, choose a speed and play the result as sound or a full-screen light flash.

Pourquoi l’utiliser

  • Translates both directions - text to Morse and Morse back to text.
  • Plays Morse with correct standard timing (dot = 1 unit, dash = 3 units, with matching gaps) rather than just displaying dots and dashes.
  • Two playback modes - an audible tone (Web Audio, no files downloaded) and a full-screen light flash for visual signalling.
  • Three speed presets, since real Morse is read by ear or eye at different speeds depending on experience.

Usages courants

  • Learning or practising Morse code by ear, at a speed you control.
  • Recreating an SOS or other distress signal for a demonstration, film prop, or scouting/emergency-preparedness exercise.
  • Decoding a Morse message you received (a puzzle, an escape room clue, a radio transcript).
  • A novelty way to send a short message - a name or short phrase - as light or sound.

Conseils pour de meilleurs résultats

  • Standard Morse timing is dot = 1 unit, dash = 3 units, gap between letters = 3 units, gap between words = 7 units - this tool follows that ratio exactly at all three speeds, only the unit length changes.
  • For light-flash playback, especially at Fast speed, use a device with a bright, high-contrast screen - the difference between "on" and "off" needs to read instantly.
  • When typing Morse to translate back to text, a single space separates letters within a word, and a forward slash ( / ) separates words - this is the standard notation, not this tool's own invention.
  • SOS is the classic test case: ... --- ... - three dots, three dashes, three dots, with no inter-letter gap traditionally, though this tool renders it with standard letter spacing for clarity.

Questions fréquentes

It flashes your screen full white/black in genuine Morse timing, which works for practising or demonstrating light signalling (like a lamp signal) at close range. It is a phone or laptop screen, not an actual signal lamp, so range and visibility depend entirely on your device's screen brightness.

Separate the dots and dashes of one letter with nothing (no space), separate letters with a single space, and separate words with a forward slash surrounded by spaces, like "... --- ... / ...- .. .--." for "SOS VIA". The translator trims extra whitespace automatically.

All three speeds use the identical dot:dash:gap RATIO (1:3:1:3:7) - "Slow" just makes one unit last longer in milliseconds, so every dot, dash and gap scales together rather than the rhythm changing.

It is synthesized live using the Web Audio API - a single sine-wave tone switched on and off with correct timing - so there is nothing to download and it works offline once the page has loaded.
