Text to Morse Audio
Type a message and hear it as Morse code: set the speed in words per minute, add Farnsworth spacing for practice, pick the tone and waveform, and download the result as a WAV file. The audio is generated in your browser.
How to use the Text to Morse Audio
- Type or paste your text. Characters without a Morse code are listed and skipped.
- Set the speed: 15–20 WPM is typical; tick Farnsworth spacing and lower the effective speed to learn by ear.
- Choose a tone (600–700 Hz is common) and a waveform; sine is the cleanest.
- Press Play to hear it while each letter lights up, or press Ctrl+Enter in the text box.
- Press Download WAV to save the audio for practice, videos, games or ringtones.

Morse timing at common speeds
| Speed | Dit | Dah | Letter gap | Word gap |
|---|---|---|---|---|
| 5 WPM | 240 ms | 720 ms | 720 ms | 1,680 ms |
| 10 WPM | 120 ms | 360 ms | 360 ms | 840 ms |
| 15 WPM | 80 ms | 240 ms | 240 ms | 560 ms |
| 20 WPM | 60 ms | 180 ms | 180 ms | 420 ms |
| 25 WPM | 48 ms | 144 ms | 144 ms | 336 ms |
| 30 WPM | 40 ms | 120 ms | 120 ms | 280 ms |
Worked example: "SOS" is 5 + 3 + 11 + 3 + 5 = 27 dit units long. At 20 WPM that is 27 × 60 ms = 1.62 seconds.
Tips for learning Morse by ear
- Learn characters at 18–20 WPM with Farnsworth spacing (for example 20/8) so you hear rhythms, not individual dots.
- Practice 10–15 minutes a day; short, regular sessions work better than long ones.
- Copy common words and call-sign style groups (CQ, DE, 73, RST, 599) once you know the alphabet.
- Export WAV files to practice offline on your phone, and use the Metronome to feel a steady dit rhythm when sending by hand.
Prosigns and common abbreviations
Prosigns are two letters sent as one character with no letter gap between them. Type them in angle brackets and the tool joins them for you: <AR> (·−·−·, end of message), <SK> (···−·−, end of contact), <BT> (−···−, new paragraph or pause) and <KN> (−·−−·, go ahead, named station only). SOS is also sent as a single prosign in real distress traffic, ···−−−···. Common abbreviations include CQ (calling any station), DE (from), 73 (best regards) and 88 (love and kisses).
Frequently asked questions
How is Morse code speed (WPM) calculated?
Speed uses the standard word PARIS, which is exactly 50 dit units long including the space after it. At W words per minute one dit lasts 1.2 / W seconds: 60 ms at 20 WPM. A dah is 3 dits, the gap inside a letter is 1 dit, between letters 3 dits and between words 7 dits.
What is Farnsworth timing?
Farnsworth spacing sends each character at full speed but stretches the gaps between characters and words, so the overall (effective) speed is slower. It helps you learn the sound of whole characters instead of counting dots and dashes. This tool uses the ARRL formula: the extra delay is (60c − 37.2s) / (s·c) seconds per word, split 3:7 between letter and word gaps.
Which characters are supported?
A–Z, 0–9 and the punctuation . , ? ' ! / ( ) & : ; = + - _ " $ @, a few accented letters (À, Ä, É, È, Ñ, Ö, Ü, Ç) and prosigns written in angle brackets, such as <SK>, <AR> or <BT>, which are sent without letter gaps.
Can I convert Morse code back to text?
Yes. Paste Morse code using dots and dashes, with a space between letters and / (or three spaces) between words, for example ... --- ... The tool detects it, shows the decoded text and plays it.
What tone frequency should I use?
Most operators like a CW tone between 550 and 800 Hz; 600 Hz is the default. A sine wave sounds clean, while square or sawtooth sound buzzier, like an old buzzer or a sounder.
Is the WAV file free to use?
Yes. The audio is generated on your device from your own text, with no watermark or limits beyond a 20-minute length. WAV is uncompressed; convert it with the WAV to MP3 converter if you need a smaller file.
