A Morse code sound generator converts text into the short and long beeps of Morse code. Type a message, set the speed and pitch, press Play to hear it, or press Download WAV to save it as an audio file you can use in a video, game, ringtone or lesson.
How to make Morse code audio
- Type your message in the box. You can write ordinary text or paste dots and dashes.
- Choose the sound. Speed sets how fast the code is sent, pitch sets how high the beep is, and tone shape changes how it sounds.
- Press Play to listen, or turn on Loop to repeat it.
- Press Download WAV to save the audio. The file is a standard 16-bit mono WAV that plays in every audio and video editor.
Everything runs in your browser, so nothing you type is uploaded. If you only need to translate text into dots and dashes first, use the main Morse code translator.
The settings explained
- Speed (WPM) is words per minute, measured with the standard word PARIS. At 20 WPM a dot lasts 60 milliseconds and a dash 180 milliseconds. Beginners usually start between 10 and 15.
- Overall speed (Farnsworth) keeps every letter at full speed but stretches the gaps between letters and words. Set it lower than Speed to give yourself time to think. It is the most useful setting for learning by ear.
- Pitch is the frequency of the beep. Most operators prefer 500 to 800 Hz because it is easy to listen to for a long time.
- Tone shape changes the character of the beep. Sine is the smooth classic. Square sounds like a buzzer or an old computer. Triangle is mellow. Sawtooth is rough, like a radio receiver.
- Radio static adds hiss behind the code, which makes practice harder and more realistic. Turn it up as your ear improves.
Every beep starts and ends with a 5 millisecond fade so the audio does not click.
Beeps and what they mean
People often search for the sound by describing it, such as "beep beep". In Morse code the length of each beep matters:
- A short beep is a dot, written as
.and said "dit". - A beep three times longer is a dash, written as
-and said "dah". - Two short beeps in a row are the letter I, three are S and four are H.
- A long beep on its own is the letter T and a short one on its own is E.
The pauses carry as much information as the beeps. A pause the length of one dot separates the beeps inside a letter, a pause of three dots separates letters and a pause of seven dots separates words. The generator follows these rules exactly, which you can check on the signal display of the translator.
The Morse code sounder
A Morse code sounder is not a computer program. It is the original telegraph receiver: an electromagnet that pulls a small metal bar so it clicks against a stop. The click when the key is pressed and the clack when it is released are a dot or dash separated by the time between them. American telegraph operators learned to read the code by ear from the sounder instead of from paper tape.
The generator makes electronic beeps, which are closer to radio operators' "CW" tones than to sounder clicks, but the timing is identical.
Ideas for using the audio
- Practice files. Make a short message at your target speed, with Farnsworth spacing for learning, then try to write it down before you check.
- Video and games. Put an SOS, a coded message or a sci-fi signal in a film or puzzle. Use the audio decoder to confirm it reads back correctly.
- Alarms and ringtones. Short messages such as your initials make distinctive sounds. Check your phone's instructions for importing a WAV file.
- Teaching. Loop a single letter while you explain it, or generate the whole alphabet and slow it right down.
Frequently asked questions
How do I convert Morse code to audio?
Paste the dots and dashes or type the text into the box, choose the speed and pitch, then press Play to listen or Download WAV to save the audio.
What format is the audio file?
A mono WAV file at 22,050 samples per second and 16 bits. It is uncompressed, so files are small for short messages, and almost every program can open it.
Can I get an MP3?
The generator saves WAV only. You can convert a WAV to MP3 with any audio editor or converter if you need that format.
How fast can it send Morse code?
From 5 to 40 words per minute. Slow speeds are best for learning. Speeds above 25 words per minute need practice to follow.
Does the generator work offline?
Once the page has loaded, the sound is created entirely on your device, so it keeps working if your connection drops. See the Morse code app page to install the site for offline use.
Beeping, beep boop and the sound of Morse code
The sound of Morse code is a beep: a short beep for a dot and a long beep for a dash. This generator makes that beeping from any text, with your choice of pitch, speed and tone shape, and you can save it as a WAV file. It is a beeping Morse code translator in the sense that the output is the beeps themselves, so you can play a message to a friend or use it in a video or game.
