I am wondering if this can do FIR filters? Like room correction or digital XO? Could the HD-PLEX work instead of the the Streacom? Any reason for SSD vs mSSD?

 

I am using Dirac Live for room correction on a laptop with an Intel Core2 Duo P8600 @ 2.4GHz without any issues, I suspect even the Topanga with Atom N2800 runs smooth with Dirac Live as it consumes very little processing power during playback, only the generation of the filters will take a few minutes more.

I asked the question as to whether Dirac Live calculated filters and then just stopped running. My assumption is that the processor should not matter, that as you assume as well that it would just take longer. I was told no, the program is not "static," and continues to make "calculations," the entire time. Are you also running SACD iso files at the same time? You didn't mention that? I have an Intel Duo Core2 T4400 @2.20GHZ and it can not run multi-channel SACD ISOs WITHOUT constant buffer and playback stopping. There is no way it can run Dirac live in the background as it can't even run multi-channel SACD iso files alone. My Quad Core Q8200 @ 2.33GHZ barely can since Jriver switched to multi-threaded handling of SACD iso files.

 

I'm not sure how many channels you are using and what formats. I believe 5.1 SACD iso files, expanded to 7.1 with JRSS processed with an active program like Dirac Live will require quite a bit of horse power. My Quad Core has two cores pegged just with multi-channel SACD iso files.

 

I am only using two channels with resolutions up to 24/96, I can imagine that with multi-channel SACD playback you will need serious processing power.
