What is Morse Code?

Morse code is a method used in telecommunication to encode text characters as standardized sequences of two different signal durations, called dots and dashes (or dits and dahs). Named after Samuel Morse, it was pivotal in the history of long-distance communication. Today, it remains a popular skill among amateur radio operators and signaling enthusiasts.

Why Learn It?

Emergency Signals

Knowing how to signal SOS (... --- ...) with a flashlight or sound can be life-saving in remote situations.

Cognitive Challenge

Learning a new "language" keeps your brain sharp. Use our audio player to practice receiving code by ear.

Universal Reach

Morse code bridges language barriers and works even on the noisiest, weakest radio frequencies.

Frequently Asked Questions

What is the standard for visual Morse Code?

The international standard uses dots (.) and dashes (-). Letters are separated by spaces, and words are separated by a forward slash (/) or 7 units of space.

Can I listen to the Morse Code?

Yes! Click the 'Play Message' button to hear your text. You can adjust the Speed (WPM) and Pitch (Frequency) in the controls panel.

What is WPM?

WPM stands for Words Per Minute. It measures the speed of transmission. Beginners often start around 5-10 WPM, while experts can go above 20-30 WPM.

Can I change the dot and dash characters?

Yes. If you prefer asterisks (*) and underscores (_) or any other symbols, you can customize them in the settings panel.

How do I communicate 'SOS'?

SOS is the universal distress signal. In Morse, it is '... --- ...' (three dots, three dashes, three dots).

Does this tool support numbers?

Yes, it supports all digits 0-9 and common punctuation marks like periods, commas, and question marks.

Is the audio generated on the server?

No. The audio is generated in real-time within your browser using the Web Audio API. No audio files are downloaded.

Can I download the result?

Yes, you can download the visual Morse Code text as a .txt file using the 'Save' button.

Why is there a slash (/) in the output?

The slash is used to clearly separate words. Without it, a string of dots and dashes would be very difficult to read visually.

Is this tool free?

Yes, it is completely free to use for educational, hobbyist, or professional purposes.
