If you are an experienced or amateur radio operator you might want to try this versatile and powerful sound decoder designed to transcribe Morse Code tones and generate the message in text form.

Morse code is a smart method of transmitting text messages or information using a series of on-off lights, tones or clicks that can be received and understood by an observer or listener without using any special equipment.

However, if you are not a skilled listener you can use Morse Decoder to analyze audio input from your Mac’s microphone or audio input, and decode the Morse code tones into human readable text messages.

Morse Decoder comes with a simple user-oriented interface from which you can view the decoded messages along with the waveform of the received audio signal.

Moreover, Morse Decoder is also capable to automatically decode long and clean signals, but you can tweak the manual controls in order to decode more difficult signals in QRM.

Advanced users can manually configure the decoding parameters and adjust the audio frequency of an optional narrow-band DSP filter, change the threshold value above the background noise along with the WPM dot / dash speed for a better detection of the characters. You can also use the Farnsworth timing to detect spaces between individual characters.

On top of that, you can enable the audio filter for any frequency set between the 400 and 1400 Hz range. In addition, you can turn on or off the AGC, filter, squelch and WPM modes.

The Words Per Minute (WMP) detection speed can be manually locked to the desired WPM dot speed and it can automatically change anywhere between 8 and 40 WPM. What is more, you can use the High Speed WPM mode which supports code speeds between 30 and 80 WPM as well ass higher frequency dot-dash tones.

In conclusion, Morse Decoder is a simple yet efficient Morse code transcriber that promises to help you understand Morse code messages quickly and easily.
