Decode live Morse code straight from your microphone, real-time, in your browser, no recording or upload needed.
Your browser captures audio from the microphone and analyses the energy in the 600 Hz band, the standard Morse tone frequency. On/off transitions become dots, dashes, and gaps, and an adaptive timing model figures out the speed automatically.
No. Everything runs locally in your browser using the Web Audio API. The only permission you grant is microphone access, the audio never leaves your device.
The decoder targets tones around 600 Hz. If your source uses a very different pitch, or there's heavy background noise, results may suffer. Move closer to the mic, reduce noise, and use a clear tone between 400–1000 Hz for best results.
