Filters vs Automation Notification System
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Filters
This application assists in calculating electronic filter components for speaker systems. It automatically determines inductor and capacitor values based on desired impedance and cutoff frequency, and designs circuits for various speaker types. Users can visualize frequency and phase diagrams for their custom speaker designs.
- Automatic electronic component calculation
- Frequency and phase diagram display (Bode plots)
- Electronic circuit schema display
- Support for various speaker types (high, mid, low, sub)
- First and second-order filter design
- Complete filter theory and formulas

"Filters" is an application for the calculation of electronic filters for the construction of speaker systems. The program automatically calculates the values of electronic components (inductors, capacitors) of electronic filters depending by the desired speaker impedance and the cutoff frequency. The software can calculate and design the circuits (filters) for high, medium, low, sub woofer, etc... first and second order. Once calculated the filter’s circuit the app will automatically design for You the frequency and phase diagrams (Bode plots). Build the speakers of your dreams with "Filters"! Features: - Automatic calculation of the electronic components of the filters for high, medium, low, sub woofers etc... - Display of frequency and phase diagrams (Bode plots) for the calculated values of the circuit’s electronic components - Display electronic circuit’s schema (filter) - Complete theory for formulas/circuits for all the filters implemented in "Filters"
