4 channel stereo audio signal switch circuit diagram using CMOS

Using electronic diagram below, through a single switch is possible to choose one of four separate stereo channels. Internal switch is made by CMOS components, to avoid cracking that usually occur in mechanical switches.
Two type D flip-flops IC2 were assigned a divider role by connecting outputs to D inputs . Q output of FF1 is connected to the clock input of FF2, resulting in a four-bit counter.
Gates outputs control switches of CMOS IC3 and IC4.
Entry to each switch includes a voltage divider to allow the switches to work in the linear range providing low distortion of audio signals.

The circuit will require a current of only 1 mA at a supply voltage of 5 V which can be increased to approximately 15V.

Hello! I am looking at your "4 channel stereo audio signal switch circuit diagram using CMOS" Circuit. Is there a list of components to go along with this? Like C12 looks like 100 Ohm? C1 through C8 is 1uf at say 10 volts? ... Thanks for the help!

C1-C10 are 100uf(at least 10V); C11-C15 are 100nf;all resistors are 100k value

Hello, I am try to switch between two sets of stereo inputs to one output. This looks like it will do that but I am not skilled enough to complete the circuit. Can someone help me dumb it down so I can create and hookup. Thx
