First post on the forum, so please forgive me if asking questions that are already answered many times Tried search though I am looking for replacement for my desktop computer (core i3 mini-itx board with lesser specs than X86 Ultra..). Ultra would satisfy my at least most of my needs but one thing is not clear to me yet. Is the analog audio input mono or stereo? Stereo input is a strict requirement as I will be conducting audio measurements with ARTA and it needs dual channel input. ARTA of course support single channel measurements, but for loudspeaker measurements (designing and building crossovers) requires 2ch measurements to have accurate timing information as well. Planned setup would be Ultra X86 with SSD and latest Ubuntu Mate.
