Right now it's incredibly limiting to have only 1024 taps per output at the current 96KHz internal processing sample rate.

There is not a single reason why this compromise would be better than 2048 taps per Input @ 48KHz sample rate like the DDRC-24.

Please consider changing it!

Yes, please consider adding a bit more flexibility to how FIR filters can be applied!

My wishlist (for 2x4HD):
- allow setting internal processing sample rate to 48 kHz
- don't waste 6 taps per output channel if those are unused

In my case I don't care if the FIR filter is associated to input or output as my use case is pure speaker correction and each stereo channel is independent of the other.

Honestly, just to defend minidsp 

I thought the same exact thing 
and realized 1 it needs more taps or lower sample rate, right …. Or 

it’s not designed as a room correction fir but meant to be for a fir crossover…. Which if you know how to tune properly that’s all you need! 

and the 1024 taps with the proper impulse centering will make a crossover (2 way) at 80hz or higher…. 

so….. the 1024t at 96k also keeps some unwanted ringing issues down because the high sample rate…. The trade off …. Compromise…

i understand it now… the 1024t vs 2048t 96/48 
it’s a wise choice to keep 96k and 1024t 

who uses a brick wall at 80hz anyway we’re not designing sinc filters…  

The 48k plugin for OpenDrc has gobs of issues….. where the 96k plug in is so musical 

just Use it for fir crossover and you’ll have amazing SQ!! 

fir is a bit funky….. especially in floating point. Ringing and especially spacial smearing can creep into your music…. It’s completely avoided with 96k
