About this app

Morse Code: Audio Decoder is a Morse code translator, sender, and audio decoder for converting text, playing signals, and decoding Morse audio through your phone’s microphone. Convert English letters, numbers, and punctuation to International Morse code, then transmit it with sound or your phone’s flashlight.

Listen to Morse tones with your microphone and turn detected dots and dashes into readable text. Automatic WPM calibration, manual speed control, and microphone gain settings help with different signal speeds and volumes. A manual dot-and-dash decoder is also included when you want to enter Morse code yourself.

Key features
