Morse Code Translator

By default letters are separated by a space and words by a forward slash ( / ), and “Dot, dash and gap symbols” can change both. When decoding pasted Morse, a pipe ( | ), a line break or a wide gap (three or more spaces) are also accepted as word breaks.

Yes — digits 0–9 and common marks like . , ? ! / @ and more are included.

Yes. Play sounds the Morse as a tone — or as clicks, with “Sound of” set to “Telegraph sounder (clicks)” — Stop ends it and Repeat loops it; Save audio (.wav) downloads the same sound as a file. Speed (WPM) sets how fast it is sent.

Yes. Speed (WPM) sets the sending speed, with PARIS as the standard word, and a lower Farnsworth speed (WPM) keeps each letter at full speed while stretching only the gaps between letters and words — the usual way to learn Morse by ear. Both apply to Play and to Save audio (.wav).

Yes. Write a prosign in angle brackets, like <SK>, and its letters are sent run together with no gap; the Prosigns list under the chart gives each one’s code, and “Read shared codes as prosigns (.-.-. as <AR>, not +)” reads a code a prosign shares with a punctuation mark as the prosign. “Dot, dash and gap symbols” sets the characters for the dot, the dash and the gaps between letters and words — Standard symbols puts them back — and Play reads the Morse box in those symbols. Beside Repeat, Sound, Light and Vibrate choose how Play sends it; Vibrate appears only where the browser can vibrate.

Yes. “Sound of”, after the speed fields, chooses Radio tone or “Telegraph sounder (clicks)”: the sounder knocks where each dot or dash starts and more softly where it ends, with silence between, so you read the length from the gap as on a real sounder. For the radio tone, “Pitch (Hz)” sets how high it sounds, and a pitch outside the range it takes is refused with the range named. Both apply to Play and to Save audio (.wav). Tick “Show it as di-dah, to say or hum” and a read-only box writes the code as it is spoken — a dash is dah, a dot di, and a dot that ends a letter dit, so ... is di-di-dit — with its own Copy di-dah button.

Morse with no gap between the letters. Dots and dashes run together are read as one code: a letter or prosign when they happen to match one, as <SOS> does since it is sent that way, and otherwise a code that could not be read, named under the Morse box rather than dropped. Decoded text comes back in capitals, because Morse has no case, and where two letters share a code (À and Å, Ä and Æ, Ö and Ø) the first is given. A national alphabet reads the same codes as its own letters, so choose the one the message was sent in. Dots and dashes typed into the Text box are encoded as punctuation; when they look like Morse, “Decode it as Morse” reads them as Morse instead.
