Op-Amp Power Supply Quality Considerations
https://tangentsoft.net/audio/opamp-ps.html
Op-amps use a DC supply voltage, typically anywhere from a few volts on up to 30 Vor more. If the power supply is a perfect DC voltage source (that is, it gives the same voltage no matter what happens), the op-amp’s output …

The input terminal of the op amp is pulled to this virtual ground by 100k or higher after the input capacitor. While 100 k for the voltage splitter is a bit marginal for 9 4558 op amps, 1.2 kohm may be a bit of an overkill. This arrangement on 12 v supply means your input signal should be limited to about 2 vac. Maybe 2.5.

Re: Help with DC Audio Op Amp Power Supply. The first video goes into more depth on the design theory (starting around 9:40). In particular, a paper is found which states (but does not explain) that the inductors do not need to be coupled for this design to work. Look for one made by "jeever" on 2018-02-09 08:21:33.

Quality audio opamp power supply. I am working on a project that uses the TI PCM1795 32bit audio DAC, which has two differential current outputs. External opamp circuits on each output act as an I/V converter to generate differential voltage outputs (I am using the circuit on p37/39 of manual without the differential-to-single section).
