TOPIC:

The Nano AVR DL has a sample rate of 48kHz and the Nano AVR HD sample rate is 96kHz. My question is, were there technical reasons why the DL version does not handle 96kHz? Secondly, in practice, does it really matter whether the sample rate is 48 or 96? As well as blu-rays, I listen to CDs and a few flac 24/96 recordings from my Oppo 105 to my Onkyo 818 AVR, I am coming to the conclusion that recording techniques play a much more important role in sound quality than just sample rates! Last but not least, if I purchased the DL version will I be missing out in the sound department when playing blu-rays? Looking forward to your reader’s comments. Thanks Rodney.

@ Arnoldi,

A very good question and a simple answer: Dirac Live just takes a lot of DSP resources and because processing power and sample rate are tightly correlated, we need to lower something somewhere. Say you have an algorithm taking 50% of DSP MIPS @ 48kHz, it will take 100% at 96kHz because you have double the amount of samples to process.

Your comment about recording techniques vs sample rates is very much agreed! The one comment that very little people mention is the following:
- Listen to a 48k perfectly room corrected system. i.e. solving inherent acoustic issues of your room that no DAC (no matter how good they are) would ever be able to solve.
THEN
- Listen to the same system but without room correction on a DSD or 384k or whatever the latest standards being pushed to us..

I'm of course assuming you'd be doing a blind test, but you'll very quickly hear that it's not even fair play... Proper room correction like Dirac Live is just a complete different scale. The beauty is that you can do that little test with a simple PC running Dirac Live trial (free). Then when you've heard it, you can move to nanoAVR DL for a full setup.

Hoping this helps.

Hi devteam while you're here ... why is the NanoAVR HD plugin delay resolution 0.02ms when 1 sample at 96kHz is 0.01ms, is it possible to allow finer adjustment of time delay at 96kHz? (for nanoAVR and minisharc @ 96kHz)

@ hochopeper,

Oh good catch. We'll add that to the list for next update.
