Morse Code Translator: Text to Morse Audio & Signals
Translate plain text to Morse code and decode Morse back to readable English in real time. Listen to synthesized audio beeps with custom WPM speed, flash optical light beacons, and download WAV audio files.
How to Translate & Learn Morse Code in 3 Steps
Type Text or Morse
Enter English sentences in the left box, or type dots (.) and dashes (-) separated by spaces in the right box for instant decoding.
Tune Speed & Pitch
Adjust the speed slider (5 to 45 WPM) to match beginner training or high-speed radio telegraphy, and dial in your preferred audio pitch.
Play Audio & Flash Light
Press Play to transmit the message with synchronized sound beeps, optical flashing light, and phone vibration, or export as a clean WAV audio file.
The Complete Guide to International Morse Code & Telegraphy
Invented in the 1830s by Samuel Morse and Alfred Vail, Morse code revolutionized long-distance telecommunications by encoding language into rhythmic electrical pulses transmitted over telegraph wires and radio waves.
The Standard PARIS Timing Formula
To standardize Morse code transmission speeds, international telecommunications bodies adopted the word "PARIS" as the universal benchmark:
- The Word "PARIS": With inter-character and inter-word gaps, transmitting the word "PARIS" requires exactly 50 dot units of duration.
- The Dot Unit ($t$): At any given speed in Words Per Minute (WPM), the base duration of a single dot is defined by the formula: $t = \frac{1200}{\text{WPM}}\text{ milliseconds}$.
- The Dash: Exactly three times the length of one dot ($3t$).
- Character & Word Spacing: The silence between elements within the same letter is $1t$; the silence between letters is $3t$; and the silence between separate words is $7t$.
The Truth Behind the SOS Distress Signal
Contrary to widespread belief, SOS (... --- ...) does not stand for "Save Our Souls" or "Save Our Ship." It was officially adopted at the 1906 Berlin International Radiotelegraphic Convention because its symmetric sequence of three dots, three dashes, and three dots is unmistakable in noisy atmospheric radio interference and can be transmitted rapidly without pauses.
Procedural Signals (Prosigns)
Radio operators use combined letter shortcuts known as prosigns to govern communication protocol without transmitting full words: AR (.-.-.) marks the end of a transmission, SK (...-.-) signifies the end of contact, and HH (........) denotes an error correction.

Frequently Asked Questions
Separate each individual letter with a single space (e.g. ... --- ... for SOS). To separate full words, type a forward slash (/) surrounded by spaces, or three consecutive spaces.
American (Railroad) Morse code used dashes of variable lengths and internal pauses inside certain letters. International Morse Code (ITU) standardized all elements into uniform dots and dashes, eliminating internal letter pauses, and is the universal standard used today worldwide.
Yes. The audio synthesis engine uses the HTML5 Web Audio API, which works natively on iOS Safari, Android Chrome, and all modern mobile browsers. On supported Android devices, the phone will also vibrate in sync with the dots and dashes.
