The volume threshold is the value (0-255) which the measured volume in the analysed frequency must exceed to be counted as a dit or dah. The volume filter (which uses dB) discards very quiet (very negative) or very loud (close to zero) sounds and scales the size of the remaining data. There are three parameters which are not automatic: the minimum and maximum volume filter settings and the volume threshold setting. The frequency can only be certain values and the closest allowed value will be chosen. It can work as narrow-band sound DSP-filter also. If you want to fix the frequency or speed then click on the "Manual" checkboxes and type in your chosen values. CW morse code decoder - DXsoft great A program to decode morse code (CW) via sound card to text. In fully automatic mode, the decoder selects the loudest frequency and adjusts the Morse code speed to fit the data. Thus, you can easily learn morse code using a USB mp3 player, while you are traveling, for example. It is also able to generate audio files with midi, wav or mp3 format. It can convert text files into morse codes. From these timings it determines if something is a dit, dah, or a sort of space and then converts it into a letter shown in the message box. EhoCw is a morse keyer and morse code generator/decoder. CW Decoder - WD6CNF CW Decoder 2.81.2 CNET Download.Com CW Get - UA9OSV CWLab04X Beta - WN2A CW Player 4.0 CW Skimmer 1. If the volume in the chosen frequency is louder than the "Volume threshold" then it is treated as being part of a dit or dah, and otherwise it records a gap (this is shown in the lower graph that looks like a barcode). The spectrogram of the sound is shown in the main graph along with a pink region showing the frequency being analysed. It consists of a hardware audio filter section that converts the CW tone to zeros and ones. The best CW decoder that I know is one I built over 20 years ago.

You can then manage the keying from the software.
#Ehocw cw decoder serial
A serial port can be wired to a set of paddles or straight key.

It runs on your PC under windows (from NT to Vista, windows 7).
#Ehocw cw decoder generator
The 2nd instance will duplicate whatever the 1st instance of ehoCW is sending - no matter if it is the keyboard or the paddles. EhoCW is nice because it included a built in keyer. EhoCw is a morse keyer software and a morse code generator and even a morse code decoder. The decoder will analyse sound coming from the microphone or from an audio file. HERE IS A COMPLETE SETUP for EHOcw that uses only 2 instances: 1 instance for keying both the paddles and the ehoCW keyboard, the other instance of ehoCW to act like a CPO in straight key mode.
