Use . for short signal, - for long signal. Separate characters with spaces, words with /.
Morse code is a telecommunication encoding method that encodes text characters through sequences of signals (dots and dashes). Invented by Samuel Morse in the 1830s, it was one of the earliest digital communication codes.
Start at slow speed, memorize high-frequency characters (E, T, A, N, etc.) first, then gradually expand. The audio playback feature helps learn Morse code through auditory memory.
Use dot (.) for short signal and dash (-) for long signal. Separate characters with at least one space, and separate words with a slash (/) or at least 3 spaces. Example: '.... . .-.. .-.. --- / .-- --- .-. .-.. -..' means 'HELLO WORLD'.
Supports the international Morse code standard (ITU-R M.1677-1), covering A-Z letters, digits 0-9, and common punctuation. Case-insensitive. Output is automatically uppercased.
Incorrect decoding may result from: 1) unclear character separation (forgot to use spaces); 2) non-standard Morse symbols; 3) invalid characters in input; 4) errors in the Morse code sequence itself.
Character spacing: use one space between character codes. Word spacing: use a slash (/) or at least 3 spaces between words. If decoded letters are merged, character spacing is missing. If words aren't separated, word spacing markers are absent.
Currently this tool supports manual Morse code input for decoding. Audio recognition is under development. For real-time audio decoding, dedicated Morse code decoding software is recommended. The audio playback feature pairs well with manual input for practice.
