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 each overtone and each formant frequency
- Time series analysis of overtone and formant frequencies
- Analysis of differences in voice composition in different voice registers
- Analysis of whether the voice is open or closed

[Features]
(1) Real-time display
- The frequency components and intensity of the voice, and the positions of each harmonic and formant are displayed on the chart.
- The fundamental frequency (fo) and 1st/2nd formant frequency (F1/F2) are displayed numerically.

(2) Time-series display
- Changes in the frequency of each harmonic and each formant are displayed on the chart.
- Changes in timbre (Open/Closed) are displayed on the chart.

[Specification]
- Detectable fundamental frequency range: 60Hz - 1000Hz
- Selectable sampling rate: 48000Hz / 24000Hz

Note:
- Settings related to analysis and display are available.
