A morse code wav file generator written in python by Cary Dreelan VK5CD
- GNU GPL Licensed
- Based on version at http://svn.python.org/projects/python/trunk/Demo/scripts/morse.py
Improvements:
- Adding key click filter (ramp amplitude up/down)
- Cached sinusodial waves for faster performance
- More command line options:
-
- Specify sample rate
-
- Frequency of morse signal
-
- Amplitude of signal
-
- Words per minute
-
- Letter spacing as percentage (allowing Farnsworth style)
- -o outfile # name/path of file to create
- -f morse_freq_hz # Frequency in hz of tones to generate, default 850 Hz
- -s sample_rate # of wav file, default 22050 Hz
- -w words_per_minute # default is 25 wpm
- -a amplitude # 0 (silence) to 32767 (loudest), default 30000
- -l letter spacing % # Default is 100%, increase for Farnsworth style
- -v verbose # Output details about what is to be generated, including morse representation
- [ words ] # Actual words to be converted, either as cmd line options, or can be stdin
Generate 'hello_world.wav' test file with default parameters in current directory:
./morsewav.py -o hello_world.wav hello world
Convert a book text file into a morse wav file with additional letter spacing (eg. Farnsworth style)
cat book.txt | ./morsewav.py -o book.wav -l 200
