Morse Decoder

       Mac OS

The HotPaw Morse Code Decoder translates Morse Code CW audio into text. The application includes an audio spectrum graph to view the frequency of any Morse Code tones, and an optional DSP narrow band audio filter to help filter out background noise. Both automatic and manual code speed and detection sensitivity are supported.

If the audio filter is enabled, the filter can be set for frequencies in the range of 400 to 1400 Hz. Click the spectrogram to set the audio filter to the desired frequency of signal. Checkboxes can be used to toggle squelch, AGC, filter and WPM modes.

The Morse code WPM (words per minute) detection speed is automatically adaptive from about 8 to 40 WPM, and can be locked to the current estimated WPM dot speed (WPM lock icon locked). There is a High Speed WPM Mode which may work for code speeds in the range of 30 to 80 WPM, and which also supports higher frequency dot-dash tones.

It may take several initial and immediately preceding characters containing both dots and dashes before the WPM speed estimation starts to get close to the actual WPM. Background sounds and signal fading can interfere with detection and decoding. The quality of detection depends on the signal level, signal to noise ratio, stability of the frequency and WPM speed, and keying "fist" quality.
