I just need PEQ, Xover, and Time Alignment functions, as long as I have all that I'm happy.

Is this true for Nano Digi that there is a resampling to 48 kHz? In that case, SQ may not be very good I imagine for 44.1 kHz sources (>99%) ?

nanoDIGI works with 96kHz with current plugin. So, there will be resampling if necessary but to 24/96!

The mini divi re-samples everything down to 48kHz.

mini divi ? probably a typo

The samplerate of the DSP is defined by the plugin and the miniDIGI will resample to the samplerate of the DSP/plugin.
That's 48kHz for all 2x4 platform plugins and the 10x10 plugin of 2x8 platform and it's 96kHz for the 4x10 plugin on miniDSP 2x8 and nanoDIGI.

I'm currently using the "2x4" as EQ for a Bose 901 (+ room correction) so my audio standards are not the highest
A bit off topic , but could you post your eq curve for the 901(which series do you have .) . I've been using my 2x4 for the same purpose with a pair of 901 ii

Thanks

Hi Curry

Thanks to confirm. I guess the more the SW is complex, the more CPU is used which limits the usable sampling rate... I was informed btw by MiniDSP that they might have 192kHz for the nanoDIGI in the future, and that FIR is not available on the nano DIGI, only SHARC and OpenDRC.

Can someone explain me the effects (measurements and SQ) not to work at a multiple of 44.1 ? are some samples lost or some jitter appear ? Is it audible ? (a transparency check could probably done with the board inserted with no EQ or compensated EQ)

Jean-Louis

Just curious what ever happened to this adapter card? Almost a year later now and still nothing that I see? Still considering this approach for my car Android front end especially since android now supports the XMOS USB to I2s interfaces natively.

Hi, I would like to know if the project of the adaptator card for Minisharc and Buffalo III is near to be released.
thank you
