What are you most concerned about? Power? CPU time? Code memory? Data memory?
all of the above
can switch off those parts of the hardware that you don't need. That might have some impact on the power consumption, positive or negative.
That's what we want to know more about.

Re: VS1053 decode streaming USB audio?

Thx for that! But i don't see equalizer application or plugin for the VS1010.
And i don't see any VS1010 modules on ebay or aliexpress.
These are the reasons we're targeting the VS1053.
Any suggestions?
thx

Re: Analog-In to PEQ?

I want to switch between analog input and MP3 decoder

, each one routed through PEQ.

Not simultaneously.

Are you saying analog input cannot use PEQ?
