Despite hunting the internet I could only find other people looking for similar drill tapes but no actual audio files.
macOS has an excellent text to speech synthesiser so I found some software to convert text to morse in a wav file and combined it with the macOS "say" command and now have a system that can generate random sequences.
You can hear a short sample here.
I've forked the original repo and put my version here. The bulk of the work is by Thomas Horsten but hasn't been touched for years.
I've done the following:
- Made it build on macOS, note it needs libsndfile (brew install libsndfile)
- generate.py generates wav files for the morse and spoken character
- makePractice.py makes a wav file with random sequences of letters
The silence between the morse character and the spoken character can be tuned as can the silence between groups.
I've put a full length drill recording up here. This one repeats each letter three times.
