SampleTone.py

simple wave genelator, example

python3 SampleTone.py -w sine -P -270 -180 -90 0 90 180 270 -f 30 -t 0.3 -v 70
python3 SampleTone.py -W sine square triangle sawtooth dc -f 30 -t 0.3 -v 70

SampleSquareFourier.py

square wave generator, example

python3 SampleSquareFourier.py -f 30 -t 0.3 -v 70 -W SF1 SF2 SF3 SF4 SF5 SF30

covid19-seat.py

Idea is from this. Calculus it and draw it into wav file.

$ python3 covid19-seat.py
parameters...
{'Output': 'covid19-seat.wav', 'NumSeconds': 4, 'SampleRate': 48000, 'Resolution': 2, 'ChannelInfo': [{'Wavform': 'cos', 'Frequency': 0.15915494309189535, 'Volume': 20, 'Phase': 0}, {'Wavform': 'Covid19', 'Frequency': 0.15915494309189535, 'Volume': 20, 'Phase': 0}]}
Integral value: 3.141593

The output...
Upper graph is cosine from -2 to 2 with 20% scale
lower graph is this graph from -2 to 2

note:
Due to it output to wav file, it can only present the time domain from 0. Due to it output to wav file, its y axis present from -1 to 1.
