Voice Matrix Monitor

This application is a monitor for analyzing the overtones and formants of the voice.
For example, you can use this application for the following purposes:
- Measurement of voice frequency
- Measurement of voice overtone and formant frequencies
- Analysis of differences in voice composition in different voice registers

[specification]

- Display of the fundamental frequency in numerical values and pitch names
- Maximum frequency that can be displayed: 1000Hz, 2000Hz, 3000Hz, 4000Hz
- Indication of overtone and formant position
- Numerical display of formant frequencies (f1, f2)
