Frequently Asked Questions

What is Morse code?

Morse code is a method of encoding text characters into sequences of dots (.) and dashes (-), also called dits and dahs. Developed by Samuel Morse in the 1830s, it was originally used for telegraph communication. Each letter, number, and some punctuation marks have a unique Morse code pattern.

Can I listen to the Morse code audio?

Yes. Click the 'Play' button to hear the Morse code as audio tones. You can adjust the playback speed in words per minute (WPM) and the tone frequency in hertz. The audio is generated using the Web Audio API directly in your browser.

What characters are supported?

The converter supports all 26 English letters (A-Z), digits (0-9), and common punctuation marks (period, comma, question mark, exclamation, slash, parentheses, ampersand, colon, semicolon, equals, plus, minus, quotation marks, and at sign).

How are words and letters separated in Morse code?

In Morse code, individual dots and dashes within a letter are separated by a short gap. Letters within a word are separated by a medium gap (typically 3 dot-lengths). Words are separated by a longer gap (typically 7 dot-lengths). In written form, letters are separated by spaces and words by slashes (/).

How do I write SOS in Morse code?

SOS is three dots, three dashes, three dots (... --- ...), sent as one continuous signal with no letter gaps. It was chosen as the international distress call because the pattern is simple and unmistakable. Type SOS in the text input and play the audio to hear it.

How do I decode Morse code back to text?

Switch the direction to Morse to Text and paste the dots and dashes, using spaces between letters and a slash or larger space between words. The tool maps each pattern back to its character. If decoding fails, check that letters are space-separated rather than run together.
