Play generated wave sound with Python and Sounddevice module.
- Initialy octave number is 4.
- Special algorithm for seamless frequency transition and noise reduction
- Use callback procedure for directly calculate sound waveform
- Sine, square, saw, trapeze or triangle waveforms
- Additional tools for watch form and spectrum audio signal
