Creating a guitar looper

Hello!

I am very interested in creating a guitar looper. This machine will get a guitar waveform and record it and then loop the soundwave.

To do that i will have to have a SOC that has not only an ADC, as everyone has, but also a DAC (maybe 12 bit?)

Will these low cost development platforms work for this kind of application?

These two seem the same! What is the difference between them?..

Also, in their characteristics, i couldn't find if they contain DACs.

Not only that, i couldn't understand the SOC that these two had?

Is this the one?
