Morse Audio Decoder

Decode live Morse code signals using your microphone. Real-time tone detection for CW practice and reception.

How It Works

The decoder analyzes audio from your microphone, detects tone on/off patterns, and converts dot-dash sequences into letters using timing thresholds.

Tips for Best Results

Use a quiet environment, adjust sensitivity to match signal strength, and set WPM to approximate the sender's speed. A pure tone around 600—800 Hz works best.
