Frequently asked questions
How are spaces handled?
A single space between Morse letters separates letters; three spaces (or more) separate words. The decoder is tolerant of varying whitespace.
Does the audio match real CW?
Yes — 600 Hz sine tone, 80 ms dot, 240 ms dash, with the standard 1:3:7 timing for inter-element / inter-letter / inter-word gaps.
Are accented characters supported?
International Morse has codes for some accented letters (À, É, Ñ, etc.) but support varies. This tool covers the ITU-R M.1677-1 core set: A–Z, 0–9, and common punctuation.
