Making Morse MlDl Files 


Several people have contacted me about making computer audio files of Morse. Why would you want to do this? Some reasons:

Distributing material for code practice sessions, attaching to emails to excite. interest or irritate other Morse people. or to use as audio introductions to Ham websites. Ideally, clicking on such a file should bring up one of the standard audio players to play the Morse through your soundcard.

It's relatively easy to generate a WAV file with a software  package such as Goldwave or VLC  from audio Morse generated either externally, input through the soundcard, or from Morse keyboard software such as CWType — if your soundcard supports duplex operation. However, WAV files are very large. With an appropriate plug-in. you can convert WAV to MP3 files, but even these will be relatively large. The solution is to make a MIDI file. as used for recording music. Instead of storing sampled sound directly. MIDI files store information about how the sound is to be generated in the soundcard. Thus. being "interpreted". they are much smaller.    Rob, KA2BEO distributes “CWMIDI”. a PC program that does this http://www.natradioco.com/Nrprods2.htm
