How is Room correction and EQ processing performed in Wiim ultra?

[Valentino]

Maybe today (check out what RME can do for you?). I used PLparEQ running under Console on a PC for many years. IIRC it upsampled 44.1 to 88.2 for calculation. At the time I had all files that were anything else than 44.1 resampled in an external program.
What I can say is that the MiniDSP Flex Eight with it’s input FIR filter employed for phase correction (2048 taps at 96 kHz is not usable below 100 hz or so) yields the best sound I’ve had from this speaker system.

Thanks for the tip, I will check it out.

”2048 taps at 96 kHz is not usable below 100 hz or so” are you saying it does not perform well for low frequency corrections?

Glad to hear you are enjoying your system, mine is still just causing me headaches

Am I the only one thinking that a device like the Eversolo A8 with it’s price tag, doing resampling to 48KHz when using EQ is really poor design!

The original MiniDSP 2x4 (non-HD, which is long out of production now) did its internal processing at 48 kHz, but it was <$100 back then. The current 2x4 HD (currently sold for $225) does its internal processing at 96 kHz.

So yes, looks like they went cheap with the A8.

Yes, if I try to go lower the intended phase correction also makes frequency corrections. Better to leave it alone.

I see, less is more!
