International Morse Code Decoders

Decoders

These Morse decoders attempt to write down Morse code based on listening to a sound file, the microphone or watching your gaze through a webcam. They are all a bit experimental.

Audio Decoder

Convert from Morse code sound into text using your computer's microphone or by uploading a sound file. It automatically adapts to the speed of the Morse code and its frequency.
