Reaper, already installs with all the plugins you will need to create a customized and high quality sounding morse code practice oscillator. Here is a short video showing the plugins in action.
(REAPER is available for all operating systems) Here is a short video with an overview of this:
Reaper, has everything you need to make your own morse code app. Using the plugins that already install with REAPER, you can customize your own code practice oscillator. This video is a short live demo that will show you these plugins "in action" and how it sounds.
Instead of creating in hardware a 'clean" and well shaped CPO, we use a harsh square wave from a 555 to send the morse tones into the MIC JACK. From there the first plugin, REAGATE, converts the ON // OFF time of the cw notes into midi messages, that are used to key the next plugin - SINE WAVE SYNTHESIZER. We filter the SINE WAVE SYNTHESIZER and hear the tones in the sound card.
(you can also send this high quality morse code audio over the internet for an online qso using WebRTC or many other voip(s))
Here are the plugins used:
1. REAGATE: takes any kind of morse code audio tone cw signal coming into the MIC IN or LINE INPUT of your sound card and converts it to a MIDI MESSAGE output.
2. REASYNTH: takes the MIDI MESSAGE from REAGATE and creates an exact duplicate of the original cw note as provided by your morse code tones inputting via the MIC IN or LINE IN jack.
3. APPLE 12-POLE BANDPASS FILTER: cleans up the edge noise from the generated morse code audio tones from REASYNTH.
4. AUDIO SPECTRUM ANALYZER
