When a dedicated virtual audio device is used it may be handy to listen to the signal. Most audio based decoding software will also require proper filtering of the signal of interest. MorseAngel will tune on the signal with highest power peak so make sure you filter the signal of interest correctly in SDRangel. Output: Step 3: Download Audio Sound or play around with different options. Input: Step 2: Get Morse code or Text Message as output based on your input. Step 1: Enter Text Message to translate it to Morse code or vice versa. AGC is convenient for voice SSB but may distort the CW envelope too much. Morse Code Translator/Decoder with Audio Play and Download. It is also recommended not to use AGC with MorseAngel. Things work similarly for any external program piping audio from SDRangel. Details on how to create a virtual audio device and use it in another software is covered in the WSJT-X Wiki. With MorseAngel it is recommended to use a 8 kHz (8000 S/s) sample rate. If you do not want to use the audio mix because there is something else going on there you can create a dedicated virtual audio device and use it as the audio output device (check the plugin documentation for details). Alternatively any decoding program based on audio can be used.Ĭonnection with SDRangel is done simply through the audio device. Please check the readme of the MorseAngel project for details on its usage. Encoding processes are deliberate and most often. Decoding from audio can be performed using the MorseAngel companion software that is based on Morse code recognition from audio using a Deep Neural Network. Morse code, once used by militaries to convey strategies and secrets. Bottom lineĪll in all, CwGet morse decoder comes with a handy suite of features for helping you decode Morse code via a sound card, and is suitable especially for power user.Any channel plugin supporting audio can be used but most probably the SSB demodulator is going to be used for true CW (on-off keying). A desired file is selected by the 'File > Decode From File' command. CwGet can decode signals from sound file (WAVE-file) also. A tool for monitoring popular web-cluster service from OH9W/OH2AQ Radio Club. Output: english text corresponding to the inputted morse. Other notable configuration settings enable you to alter the colors for several parameters, select a rig controlled by Omni-Rig, and enable the using of mouse wheel for tuning. A program to decode morse code (CW) via a sound card to text. More specifically, to develop such a morse code recognition system, we will decipher morse code audio into english text, irrespective of the sound source used to generate the morse code. The text can be altered by opting for an English, Russian, Swedish or user-defined charset, catching word by one mouse click, copying transferred data to the clipboard, inserting time marks to a captured file and using the UTC time. If you have multiple sound cards you can pick the desired one, select the input soundcard channel, provide the real soundcard sampling rate, as well as choose the output soundcard number and channel. The application offers support for several filters, and there are two sets of FIR and IIR filters that you can make use of. Importing options and filtersĬwGet morse decoder gives you the possibility to clear the received symbols, save the decoded text to a file, open the buffer data in Notepad, import a file or WAV captured file, as well as decode data from a custom WAV item. Several handy buttons are integrated in the main window for helping you activate key features with a single click, namely automatically adjust the frequency control, jump to the peak frequency in the bandpass, automatically go to the peak frequency of the strongest signal after detecting a pause, as well as limit the CW speed variation by values (in LPM) defined by parameters that are placed at the left side of this function. What’s more, you can use zoom functions and hotkeys in order to alter the frequency scale of the spectrogram and move a part of the spectrogram to left or right by dragging it with your mouse. The working frequency of the filter is revealed with the aid of a red line, and you can also make use of a ruler which shows frequencies of sound spectrum. Start using audio-decode in your project by running npm i audio-decode. The help manual may prove to be quite useful in case you are interested to find out more about the utility’s capabilities.ĬwGet morse decoder displays the current spectrum of a signal (blue line) and peak detector (green line) in the main window. Latest version: 2.2.0, last published: 6 days ago. The GUI is not highly intuitive so you need to take some time to experiment with the built-in features. Plus, it can be used as a narrow-band sound DSP-filter. CwGet morse decoder is a lightweight Windows application designed specifically for helping you decrypt Morse code via a sound card.
