What is Morse code audio?
Morse code audio is a single tone that switches on for dots and dashes and off for the gaps between them. A dot is one unit long, a dash three; the silence between symbols, letters and words follows a strict 1 : 3 : 7 ratio. Because every timing derives from one unit — the dot — the same text sounds identical on any properly set transmitter, which is what made Morse usable across the world’s radio bands.
How to set the right speed
Speed is measured in words per minute (WPM), and one dot lasts 1200 ÷ WPM milliseconds — at 20 WPM that is 60 ms, and a dash is 180 ms. Beginners should stay at 5–10 WPM until letters become automatic; casual practice sits comfortably at 15–20 WPM; amateur radio exams expect 20 WPM or more. Set the slider, press play, and adjust until copying by ear feels like work but not struggle.
Common uses
People use Morse audio for amateur radio practice, classroom listening drills, escape-room clues, accessibility projects, and — more often than you would think — to double-check an engraved gift before it is permanent. Downloading an MP3 makes all of these portable: the file plays on any phone, and the whole export happens locally in your browser.
Frequently asked questions
›What is Morse code audio?
It is the sound form of Morse code: a continuous tone that switches on for dots and dashes and off for the gaps between them. Reading by ear is how radio operators actually use Morse, and it is far easier to learn from sound than from a printed chart.
›What does WPM mean on this Morse code audio translator?
WPM is words per minute, and it sets the length of one dot: at 20 WPM a dot is 1200 ÷ 20 = 60 ms, a dash is 180 ms, and word gaps last 420 ms. Raise the WPM and the whole pattern speeds up proportionally.
›How do I download Morse code as an MP3?
Enter your text, press “Download MP3”, and the track is rendered in your browser and saved as morse-<yourtext>.mp3 — no upload, no waiting queue, no length cap. Very long tracks take a while to encode; raising the WPM shortens both the audio and the wait.
›Which speed should I choose?
Beginners: 5–10 WPM, where each letter is clearly separate. Casual listening or signalling practice: 15–20 WPM. Amateur radio exam preparation: 20 WPM and up. You can change speed and replay instantly, so experiment freely.
›Can I change the tone pitch?
Yes — the slider covers 400 to 1000 Hz, with 700 Hz as the default, which sits in the range most ears find easiest to track. Higher pitches cut through background noise; lower ones sound softer on speakers.
