Cw decoding software free7/29/2023 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). Checkboxes can be used to toggle squelch, AGC, filter and WPM modes. Click the spectrogram to set the audio filter to the desired frequency of signal. If the audio filter is enabled, the filter can be set for frequencies in the range of 400 to 1400 Hz. Decoding parameters that can be manually configured include the audio frequency of an optional narrow-band DSP filter, the WPM dot/dash speed used for detecting characters, the threshold level above background noise, and whether Farnsworth timing is to be used for detecting spaces between individual characters. It includes both automatic decoding of longer clean signals, as well as several manual controls to allow the decoding of more difficult signals in QRM. Morse Decoder takes audio input from the microphone or audio input on your Mac, decodes Morse Code tones, and displays the results in text form.
