Practical guidance

Decode Morse Code from an Audio File

Upload a clean recording containing Morse tones. The decoder measures signal and silence durations, estimates the dot unit, and converts recognized patterns into readable text.

Best Results

Trim long introductions and unrelated speech before decoding.
Clean single-frequency beeps produce the strongest results.
Adjust the sensitivity and run the analysis again when the first result is incomplete.
