Morse Code Audio Generator
A Morse code audio generator is a tool that turns text into a Morse code sound file. Type a message, choose the speed and tone, and the generator builds a WAV file you can play, share or download.

The waveform preview updates as you change settings. Press Generate audio to build the WAV file.
Our generator renders the audio in your browser with soft-edged tones that do not click, and supports Farnsworth spacing, 3 waveforms, 3 sample rates and up to 5 repeats.
01
What Is a Morse Code Audio Generator?
A Morse code audio generator is a synthesiser that switches a steady tone on and off in the rhythm of Morse code. Each dot is a 1-unit beep, each dash is a 3-unit beep, and the silences between them separate symbols, letters and words.
Radio operators call this continuous wave (CW). The generator shapes the start and end of every beep over about 5 milliseconds, so the audio sounds clean instead of clicking.
Inside a Morse beep
The top trace shows when the tone is on. The bottom trace zooms into the first 12 ms of one beep.

Morse Code Audio Settings Explained
Morse audio has 6 settings: character speed, effective speed, tone, waveform, volume and quality. Speed sets how fast each letter is sent, tone sets the pitch, and quality sets the sample rate and file size.
Most operators use a tone between 500 and 800 hertz (Hz) and a sine wave, which is easiest on the ears for long listening.
What each setting changes
5–45 WPM. Length of every dot and dash: 1.2 ÷ WPM seconds per unit.
3–45 WPM. Stretches only the gaps between letters and words (Farnsworth).
300–1,200 Hz. Pitch of the beep; 600 Hz is a classic radio sound.
Sine, triangle, square. Sine is soft, square is buzzy like an old buzzer.
8, 22 or 44.1 kHz. Higher sample rates sound cleaner and make bigger files.
1–5 times. Loops the message with a word gap between copies.
03
Farnsworth Timing for Morse Code Learners
Farnsworth timing is a method that sends each letter at full speed but adds extra space between letters and words. You hear every character with its real rhythm, and you get more time to recognise it.
The ARRL uses Farnsworth timing in its code practice. Set the character speed to 18–20 WPM and lower the effective speed to 5–10 WPM, then close the gap as your copy improves.
Gap lengths with letters sent at 20 WPM
Every dot stays 60 ms long. Only the silences between letters and words grow.
| Spacing | Letter gap | Word gap | Best for |
|---|---|---|---|
| 20 / 20 WPM · standard | 180 ms | 420 ms | Experienced operators |
| 20 / 15 WPM | 340 ms | 790 ms | Moving up to full speed |
| 20 / 10 WPM | 650 ms | 1.5 s | Most learners |
| 20 / 5 WPM | 1.6 s | 3.7 s | First lessons |

What to Do With a Morse Code Audio File
A Morse code audio file is useful for practice, puzzles, video projects and ringtones. WAV files play on every phone and computer and import into any audio or video editor.
A 30-second message at 22 kHz is about 1.3 MB. Choose 8 kHz for small files you want to email or embed in a game.

FAQ
Frequently Asked Questions (FAQs)
How do I make a Morse code audio file?
To make a Morse code audio file, type your message, choose the speed and tone, then press Generate audio. Listen to the preview, then press Download WAV to save the file.
What file format does the generator create?
The generator creates 16-bit mono WAV files at 8, 22 or 44.1 kHz. WAV plays on every device. Convert it to MP3 in any audio editor if you need a smaller file.
What is the best tone for Morse code?
The best tone for most listeners is 500–800 Hz. Radio operators often choose 600 or 700 Hz. Lower tones sound calmer for long sessions, and higher tones cut through background noise.
What is Farnsworth spacing?
Farnsworth spacing sends letters at a fast character speed but adds longer gaps between letters and words. It helps learners hear each letter as one sound pattern instead of counting dots and dashes.
How fast should Morse code audio be?
Beginners do best with letters at 18–20 WPM and an effective speed of 5–10 WPM. Casual radio contacts run at 15–25 WPM, and the PARIS standard sets 20 WPM at 60 ms per dot.
Is the audio generated on a server?
No, the audio is generated entirely in your browser. Your message is never uploaded, and the WAV file is built on your device.
