Ghani Lawal- ****Classic RC filter attenuates too slowly, by increasing the order you also increase the slope in the passband, unacceptable, therefore will use active Butterworth filter - Sallen Key topology
- Found website that builds active filters for you based on design specifications: https://tools.analog.com/en/filterwizard/
- Have preliminary design for all music spectrums
- Bought mono-aux cable that splits into separate power and ground wires
