Description: 实时滤波器，具有精美界面，可以开发自己的应用功能。-You can use 4 types of filters:
- Butterworth
- Chebyshev 1
- Chebyshev 2
- Elliptic
You can use them as:
- Lowpass
- Highpass
- Bandpass
- Stopband
Showing theirs features in frequency, phase and the z plane. After the desing phase you can apply the designed filter in real time to incoming audio signal from the microphone.
