Ditlamp : Traducteur de code Morse

Ditlamp is a Morse code translator, decoder and trainer in one offline app. Type a message and your phone sends it as sound, light and vibration. Hold the phone to a tone or a blinking lamp and it reads the code back. Spend five minutes a day and you learn Morse code by ear, one letter at a time.

SEND: A MORSE CODE TRANSLATOR THAT PLAYS

Type or paste text and the code writes itself under every letter. Paste dots and dashes instead and the direction flips on its own. Press Send and a single timeline drives the sidetone, the signal lamp on screen, the phone's flashlight, vibration and screen flash, so all five stay in step. Set the speed in words per minute, add Farnsworth spacing to slow the gaps while the characters stay fast, change pitch and weight, and share the result as text, as code or as an audio clip. It also works as a Morse code generator for puzzles, gifts and escape-room clues.

LISTEN: A MORSE CODE DECODER FOR SOUND AND LIGHT

Open Listen, allow the microphone when asked, and hold the phone near a speaker playing a Morse tone. Ditlamp locks onto the tone, estimates the speed by itself and folds the letters onto a copy pad. This Morse code decoder keeps doubtful letters outlined instead of guessing them, and plain noise prints nothing. Point the camera at a lamp to read light, or open a recording and replay it at half speed. A clear tone reads best. Audio and camera frames are analysed on the phone and never saved.

LEARN MORSE CODE BY EAR

The daily session takes five minutes and follows the Koch method: you hear every character at full speed from the first lesson, and at 90 % correct the next one joins. Your weakest letters come back first the next day, and the results show which pairs you mix up. A board of 41 characters fills in as you go, a speed ladder keeps your best clean copy at each speed, and a missed day does not break your streak. Copy on your own keyboard or in your head. If you would rather not use sound, learn by vibration or by light. As a Morse code trainer it covers beginners and radio amateurs alike.

SEND BY HAND

Practise on a straight key or on two paddle zones, iambic A or B. Each element is measured against a unit ruler while you hold it, and the same decoder reads your fist: “Dahs are short at 2.4 dits; aim for 3.”

ALPHABETS, PACKS AND CHART

Fourteen alphabets: Latin with accented letters, Cyrillic (Russian, Ukrainian, Bulgarian, Belarusian, Serbian, Kazakh), Greek, Hebrew, Arabic, Persian, Japanese Wabun, Korean and Thai. Practice packs: Words, Call signs, Q-codes, Prosigns, Abbreviations, Contest exchange, A standard contact, Short English words, Numbers. The chart shows the alphabets as a grid or a dit-dah tree. Tap a character to hear it. Sent and received messages stay in the log.
