In written Morse, you never run characters together, so spacing is what keeps a message readable. The standard print convention separates the dots and dashes of a single letter with no gap, separates one letter from the next with a single space, and separates whole words with a slash. So "HELLO WORLD" becomes ".... . .-.. .-.. --- / .-- --- .-. .-.. -..". When sent by sound the same rules apply as silence: the gap between letters lasts three dot-lengths and the gap between words lasts seven. Mixing these up is the most common reason a decoded message comes out garbled. This translator applies the space-and-slash convention automatically when encoding, and reads it correctly when decoding, so paste your text or Morse above and the spacing is handled for you.

A dot (called a "dit") and a dash ("dah") differ only in length, and that length is defined as a strict ratio rather than a fixed number of seconds. A dash lasts exactly three times as long as a dot. The silent gaps are timed against the same dot unit: one dot-length of silence sits between the parts of a single letter, three dot-lengths separate letters, and seven dot-lengths separate words. Because everything scales from the dot, faster sending simply shortens the dot while keeping all ratios identical, which is why Morse stays legible at any speed. Getting these proportions right is what makes code sound rhythmic instead of random. The audio playback here follows the standard ratios precisely at every speed, so paste a message above and listen to hear correctly timed dits and dahs.

SOS is three dots, three dashes, three dots: "...---...". Although people remember it as "Save Our Ship," SOS was actually chosen because that unbroken pattern is unmistakable and hard to confuse with anything else. It is a prosign, or procedural signal: a sequence run together as one character with no letter gaps inside it, used as shorthand for an action rather than as a word. Other common prosigns include CQ, a general call inviting any station to reply; AR, marking the end of a message; and SK, signalling the end of a contact. Operators send these constantly to keep exchanges short. This tool includes a dedicated Prosigns reference listing each one with its meaning, so open the Prosigns tab above to look them up or hear how SOS and the others sound.

Morse is copied by ear, so the pitch of the tone matters for comfort and accuracy over long listening sessions. Many operators settle on a tone near 600 Hz because it sits in a range the human ear hears clearly without being shrill or fatiguing, and it cuts through background static well on the air. There is nothing magic about the exact number; some prefer 500 to 700 Hz, and the right choice often depends on your hearing and your equipment. What matters is picking a steady, pleasant pitch and sticking with it so your brain learns the rhythm rather than the frequency. This translator lets you set the tone anywhere from 300 to 1000 Hz and defaults to 600 Hz, so adjust the frequency control above to find the pitch that is easiest for you to copy.

Words per minute measures how fast Morse is sent, based on a standard reference word — "PARIS" — that contains exactly 50 dot-units including its trailing word gap. At 5 WPM the tool sends five of those words each minute, and at 20 WPM it sends four times as many by shortening every dot, dash, and gap proportionally. Because all the timing ratios stay fixed, only the dot length changes, the rhythm of each letter sounds identical at any speed. Beginners usually start slow to recognise patterns, then raise the speed as their ear catches up. This translator offers 5 to 35 WPM with one-tap presets from Beginner up to Expert, so set the speed above, play your message, and step it up gradually as your copying improves.
