Translate Text to Morse Code and Back, with Audio
Morse code encodes letters as sequences of short and long signals, designed in the 1840s so information could travel down a single telegraph wire. It outlived the telegraph because it needs almost no bandwidth and can be sent by sound, light, radio or tapping — which is why it persisted in aviation, maritime use and amateur radio long after faster systems arrived.
This translator converts in both directions and can play the result as audio using proper timing, where a dash lasts three times a dot and the gaps between letters and words are themselves part of the code.
Key features
- Bidirectional — type text to get Morse, or paste Morse to get text back.
- Audio playback — a real oscillator at 600 Hz with correct PARIS timing.
- Adjustable speed — 10 to 25 words per minute, from learner pace to practised operator.
- Full character set — letters, digits and the standard punctuation marks.
- Clear conventions — a space separates letters, a forward slash separates words.

Frequently asked questions
What is SOS in Morse code?
Three dots, three dashes, three dots: ... --- ... It was chosen in 1906 purely because the pattern is unmistakable and easy to send under stress. It does not stand for "Save Our Souls" — that came afterwards.
How is Morse timing defined?
Everything is a multiple of the dot. A dash is three dots long, the gap between symbols is one dot, between letters three dots, and between words seven. Correct timing is what makes Morse readable by ear.
What does words per minute mean?
Speed is measured against the standard word PARIS, which is exactly 50 dot-units long. At 20 WPM one dot lasts 60 milliseconds. Beginners usually start around 5–10 WPM.
Is Morse code still used?
Yes, mainly in amateur radio, where it is prized for cutting through noise at very low power. It is also still recognised in aviation navigation beacon identifiers and occasionally used as an accessible input method.
