I was thinking about all of the interference from SMPS and had an interesting idea. I know alot of people run their systems from batteries to get rid of mains issues.
If we assume that a critical low voltage component (DSP, codec chip, etc...) is consuming low power, would it be an idea to run it from a small bank of LiPO batteries? And have them automatically charge when it isn’t being used?
Many of the small atmel micro boards (feather, arduino mkr, etc) have this functionality built in. There are a number of low-noise linear supplies that can handle the small drop in voltage as the battery is drained.
I can’t think of a downside. (Assuming, of course that it is not being used 12h/day daily to kill the batteries from charge/discharge cycles)

The actual calculation result will not be affected by the power feed. Actually, you have to work pretty hard to get bit errors in any digital audio component.
What might happen is that the connected units could pick up disturbances from the DSP unit as they share earth etc.
DSP is math - nothing else.
Just so that is clear.
