Live Morse Code Decoder
Listen continuously through your microphone and translate Morse beeps as they arrive. Watch the level, dominant frequency and estimated speed while the transcript streams.
Clear, steady single-tone Morse works best. Audio is analysed continuously in this browser and is never uploaded.
How it works
A real-time Morse listener
Start listening, place the microphone near a clean tone source and keep background noise low. The live decoder tracks signal transitions continuously instead of stopping after a short recording.
Best results
Reading the live meters
Input level shows whether the signal is strong enough, dominant tone helps you position the source, and estimated WPM adapts from detected dit length. The transcript remains editable by copying it into the main translator.
