Re: Analog Switch question

I actually have another question regarding analog switches. I have
this image:

I'm trying to convert the voltage reference of a source in another
reference for the analog switch. If the source is referenced to
ground, then I would like to be able to reference it to Vcc/2 instead.

In my diagram, does it accomplish the task?

Also, for the capacitor values, I am assuming that I have to pick the
value based on:

- minimum frequency to pass thru the low pass filter
- frequency relationship is also dependent on the parallel combination
of the voltage divider resistors
- capacitor voltage rating is based on the voltage difference between
VCC/2 and reference voltage of the source

Are these assumptions correct?

Also, for audio bypass capacitors, what other characteristics should I
know?

Thanks!
