Filter Creator helps you to understand the mathematics of discrete and continuous audio filters and is particularly aimed at students of signal processing classes. Filter Creator allows you to define an audio filter, view some of its properties such as amplitude and phase response, and test its effect on up to four minutes of recorded sound.
Features:
- Define a filter by setting its poles and zeros on the complex plane
- View its phase and amplitude response
- Record up to four minutes of sound and test the effect of your filter
- Switch between the discrete and continuous domains
