How does the microphone decode work?

Click the Mic button and tap short/long tones or use a key against a surface near the mic. The tool measures audio amplitude over time and classifies bursts as dots or dashes based on their duration relative to the WPM setting.

What speed (WPM) should I use?

The default is 13 WPM, which is a comfortable learning speed. Adjust the slider up to 35 WPM for faster practice or down to 5 WPM for beginners.

Which characters are supported?

All 26 letters (A–Z), digits (0–9), and common punctuation marks including period, comma, question mark, slash, and more per the ITU standard.

Can I copy the decoded output?

Yes. Click the Copy button below the output box to copy the result to your clipboard.
