Best practice is to connect a capacitor say about 100nF close to the supply pins of each ic and a large one (about 100uF) where the power supply enters the board.
You might want to connect a small fi ... |

For the right three opamps I'd use three attennuverters so you can have a volume setting and invert the signal with the same potentiometer | |
