Decoder Settings

0.10

Adjust sensitivity; increase this value in noisy environments.

150 ms

Maximum duration recognized as a dot (.)

400 ms

Minimum duration recognized as a dash (-)

300 ms

Pause between characters before converting Morse to letters


Adjust these parameters to match your input rhythm. If decoding is inaccurate, increase the gap between dot and dash durations and tweak the pause duration so the system can better identify character boundaries. Waveform settings affect visuals only.

Tips

  • Short tones represent dots; tones about 3x longer represent dashes.
  • Pause briefly between letters and longer between words.
  • If results drift, adjust the threshold or dot/dash durations.
  • Use in a quiet environment to reduce noise.
