How it works
Type any text and it is encoded to ITU Morse code instantly, then turned into a real CW tone: a dit is one time unit, a dah is three, gaps inside a letter are one unit, between letters three and between words seven. Speed is set in words per minute using the standard PARIS reference, so 20 WPM gives a 60 ms dit. Lower the overall speed below the character speed and the tool switches to ARRL Farnsworth timing — the characters are still sent at full speed but the spacing stretches, which is how most operators learn to copy code.
Playback uses the Web Audio API with a 5 ms rise and fall on every element, so the beeps sound like a proper keyed sidetone instead of clicking. Download WAV renders the same signal offline to a 44.1 kHz 16-bit mono WAV file that you can drop into a video, a practice playlist or a phone ringtone. Everything happens inside this tab — your text is never uploaded, there is no account, no ads and no tracking.
Frequently asked questions
How do I turn text into Morse code audio?
Type or paste your text in the box. It is encoded to ITU Morse code instantly and the page shows the dots and dashes, the dit length in milliseconds and how long the audio will run. Press Play Morse to hear the keyed sidetone through your speakers, or Download WAV to save a 44.1 kHz 16-bit mono WAV file you can drop into a video, a practice playlist or a ringtone. Everything is generated with the Web Audio API inside your browser tab, so your text is never uploaded.
What do the WPM settings do, and what is Farnsworth spacing?
Speed is measured in words per minute against the standard PARIS reference, so 20 WPM means a dit of 60 ms, a dah of 180 ms and three dits of silence between letters. Set the overall speed lower than the character speed and the tool switches to ARRL Farnsworth timing: each letter is still sent at full character speed, but the extra delay is spread between letters and words (3/19 and 7/19 of it). That is the recommended way to learn Morse, because you train on the real sound of a fast character instead of a slowed-down one you would have to unlearn later.
Which characters can it send, and what happens to the rest?
All 26 letters A-Z, the digits 0-9 and the standard ITU punctuation . , ? ' ! / ( ) & : ; = + - _ " $ @ are supported; letter case is ignored. Anything without a Morse equivalent, such as emoji or accented letters, is listed in a short notice above the output and skipped rather than silently mangled, so you can see exactly what will be keyed before you download the WAV.
