Frequently Asked Questions
Which characters are supported?
Letters A–Z, digits 0–9, É and the ITU punctuation . , : ? ' - / ( ) " = + @, plus the widely used ! & ; _ $. Other accented letters are sent without their accents. Anything else is left out and listed under the result.
How is the timing calculated?
Speed is based on the standard word PARIS: a dot lasts 1.2 seconds divided by the words per minute, so 60 ms at 20 WPM. A dash is three dots, the gap within a letter one dot, between letters three and between words seven.
How should I write Morse code to decode it?
Use . and - (· • and − – — also work), one space between letters, and a slash, a vertical bar or two or more spaces between words. A code that matches no character appears as � and is listed under the result.
Why can’t I hear anything?
The browser starts sound only after you select Play. Check that the tab and device are not muted. The WAV download works even when playback does not.
Are there limits?
Input is limited to 20,000 characters, and playback and WAV files to 10 minutes. The WAV uses 8,000 samples per second, which is plenty for a single tone and keeps files small.
Is my text uploaded?
No. Translation, sound and the WAV file are all produced in your browser.
