Back in the mid-1800s (that’s 1800s, not 1900s, not 20th century) communicating from one location to another was handled by Morse code, which used lights, sounds, or electric current to spell out the English alphabet.
I don’t know anyone today who knows or uses Morse code but it did make an appearance in the science fiction movie Independence Day.
Enter Morse Decoder, the Mac app which decodes Morse code in audio form and displays it in text form.
Because most people have no Morse code training, that makes Morse Decoder the perfect app to read and decode Morse code during the Apocalypse or when aliens from outer space disrupt electronic communications on earth.
Morse Decoder uses the Mac’s built-in microphone or audio input to decode the signals. It comes with a number of manual controls to enhance the audio capture, as well as a narrow-band DSP filter, and the WPM (words per minute) dot and dash speed used to detect characters.
The app is simple enough to use and the options are nominal and mostly related to handling variables in the audio signal, including options to toggle squelch and AGC. This is exactly the kind of app that experienced amateur radio operators would use to decode Morse code signals from distant locations, and it’s a good addition to any Mac user’s underground bunker.
