Decode Morse code from microphone input or audio files — directly in your browser.
USP — Only tool of its kindThe decoder analyzes audio signals in your browser — either from your microphone in real-time or from an uploaded audio file. It detects tone patterns and converts them to dots and dashes, then decodes the Morse to readable text.
The file decoder supports MP3, WAV, OGG, and any format your browser can play. For best results, use clean recordings with minimal background noise and a clear tone between 400-1000 Hz.
Yes. Click Use Microphone to start real-time decoding. The decoder listens for tone signals above the noise threshold and converts them to text as you transmit.
