Can you provide a list of these required interfaces?

l'd be happy with I2S output because that makes it easy to connect up a USB interface. I don't know enough to know what to suggest beyond that. How would you connect an ADC to a laptop? What's the best way? I have a USB 3.0 card, and USB 2.0 native on this laptop. I have almost zero experience with these kinds of converters. I have a MiniDSP USB interface, for example. I've used the Twisted Pear USB interface as well.

Well I would just include a USB connection.

Oh cool. So, which ADC are you wanting to use? Did you want a separate thread for this? The PCM4222 looks great, but I'm not married to it...

OPA1632 inputs looks good also.

I can help with a group buy or what ever.

AK5294A is what I' looking at.

I have a lot of research to do and I have to learn the Atmel procrssor.
This will take a while.

Is that for the "system controller" shown in the AK5294A data sheet?

Just be sure it has good drivers for all OS (or class 2+ windows drivers). And support at least 192khz.

If you go back a few posts and look at what Demian linked to.

Use Arduino sure but the SDR-Widget doesn't use Arduino it uses the Atmel.

The project is open source and drivers are available for three OS and several OS versions.
I don't have time to create from scratch. It's easier to take code that's already developed and modify it for my purposes.

I don't mind learning new things but one at a time. Otherwise it gets too confusing.

Why is Arduino better? Why not Microchip?

Cheers,

I can't promise there won't be headaches involved. But test applications can be tried before
committing to hardware. Hardware emulators.
