Morse Code Translator

The Morse Code Translator converts plain text into Morse code, and decodes Morse code back into readable text, in both directions from a single input box — with a Play as Audio button that reproduces the actual dots and dashes as timed beeps using the Web Audio API. It covers the full Latin alphabet, digits and the common punctuation marks defined in the international Morse code standard.

It's used for learning and practicing Morse code (hearing the rhythm of dots and dashes reinforces the pattern far better than reading it as text alone), decoding a Morse message from a puzzle, escape room, or amateur radio context, and for the simple novelty of encoding a short phrase or name into Morse for a tattoo, engraving, or bit of trivia. Letters are separated by a single space in the Morse output, and words are separated by a forward slash surrounded by spaces, matching the conventional written notation for Morse code.

The audio playback follows the standard Morse timing ratios: a dash lasts three times as long as a dot, the gap between dots and dashes within a letter is one unit, the gap between letters is three units, and the gap between words is seven units — all scaled from a base unit duration, so the rhythm sounds authentic rather than just beeping through the symbols at a flat pace. Playback is generated live with an oscillator tone, so no audio files are downloaded or played from a server.

When decoding, unrecognized Morse sequences are simply skipped in the output, and when encoding, characters with no defined Morse equivalent are dropped rather than breaking the whole conversion. This keeps the tool forgiving of minor formatting inconsistencies in pasted Morse (extra spaces are trimmed automatically) while still producing a clean, correct result for well-formed input. Everything, including audio generation, runs entirely in your browser.
