for 5V logic, common practice is to add 100nF-1µF across each IC and 10µF at the power inlet and you'll be plenty fine, with margin
the only thing to sort of worry about is the inductance of your traces forming an LC resonator with your caps, so if you feel like being extra safe you should try to keep any LC resonators away from your clock frequency

>>1531160
you can simulate an inductor to ground (for low-freq filtering) with two resistors, an op-amp, and a cap, Pic related

large inductors are not necessarily cheap. for a VU meter it's almost certainly overkill

>>1531189
typically they used the Wien-bridge and variable LC with a light bulb to control gain
later on they used the smoothed triangle approach

Clapp oscillator?

2 and 3 are the inductors. I simply made the inductors out of op-amps instead of actual inductors.
