Decode Morse Code transmitted through audio input on your iPhone or iPad. Convert the Morse Code signals into text and use a built-in audio spectrum analyzer to determine the frequency of the tones. Additionally, use the optional narrowband audio filter to minimize background noise.
The HotPaw Morse Code Decoder takes audio input from the microphone or headset input on your iPhone or iPad, decodes Morse Code and displays the results in text form. The decoder includes a built-in audio spectrum analyzer to help you find the frequency of any Morse Code tones present. There is an optional narrow band audio filter to help filter out background noise.
