NSF stands for Najda Setup File. It's a file format devised for enumerating the processing options of the board. Basically, what you're going to find in this file is the signal routing, delays, gains, filters, channel inverts etc. Everything that you're setting up within the application can be saved in a NSF file and recalled at a later time.

ARTA lets you save your measurements in a csv file that has 2 or 3 columns: frequencies, magnitudes and optionally phases. This is the file format Najda is currently accepting when it comes to loading your measurements.

Is there any chance to apply settings both (all) channels live ?
Sorry I don't get that one Can you please elaborate? (with a simple example maybe?)

Here's an old trick -- a complementary pair of FIRs can be generated by one odd-length FIR (highpass or lowpass) and a delayed signal. That'll save almost half your computation, not a big deal for 1 kHz filters, but quite useful if you're crossing over in the low mids where FIRs can be several hundred taps long.

Happy to announce that I have received the boards, they're very nice.
