Two questions about the RMC-1 & Dirac: - What is the highest sample rate at which Dirac can run on the RMC-1?
- Why isn't this on the site?
Thanks.

The first question has already been answered... The sample rate Dirac Live currently operates at in the RMC-1 is 48k. (This is controlled by the firmware, so it could theoretically change someday, but we don't expect it to.)
The answer to the second question is more a matter of philosophy...
Normally, when we talk about sample rate, the context is a discussion about "delivering the audio without altering it". For example, we would prefer that our computer or streamer deliver bit-perfect audio, and not change things like the sample rate. The reason for this is because we specifically want to avoid having the audio signal altered in any way.
However, in this context, the whole PURPOSE of Dirac Live is to alter the audio signal. This renders any possible discussion about "whether Dirac Live alters the audio signal" completely moot...
Dirac Live is definitely NOT bit-perfect; it definitely DOES alter the signal; and definitely DOES make the signal sound different. And, once you concede that bit of reality, the ONLY thing that matters is what the end result SOUNDS LIKE. Assuming that Dirac Live makes your system sound better then it's worth using. And, if it didn't make your system sound better, then it wouldn't be worth using. Of course the reason we have it is that most people agree that it usually does make things sound significantly better...
(But, either way, the sample rate it uses internally doesn't make any difference.)
Hopefully, by now, you aren't silly enough to assume that something that operates at 96k will automatically sound better than something else that operates at 44k or 48k. We all know that, in the real world, there are an awful lot of other variables involved.

I agree with this. Something like Dirac Bass Control is far more worth the effort at this point. ☺ Any news you can share on this Keith? I think many of us are interested to know whether any coding has begun, testing in lab, etc etc. I know timelines are difficult to project, but it would be nice to know if that you guys have actively started development to include this feature. Thanks in advance. |

Thanks in advance. Sorry to tag all you gentlemen, but I felt like it was far easier & quicker for you to put an answer here than to discuss over the phone. Plus, thousands of people get the update straight from you which prevents more phone calls, confusion, drama etc. Any tangible detail would be most appreciated. Thank you in advance! |

I was very hopeful that the RMC-1 would bump the ceiling for Dirac to 96kHz.
I have a good bit of concert videos and surround audio discs that are 24/96 so cutting the sample rate in half is less than optimal. Terrible? No, but not as good as the original.
I guess I'll be passing on the RMC-1 then since it's not really offering drastically more than the XMC-1 that I currently own.

I do believe if you look into other pre/pro's with DIRAC, some will claim they do 24/96 with DIRAC but they really don't. It's a DIRAC limit, if I understand correctly. And, as noted...some say they do but they really don't. I might be wrong, but dig into it. Regarding whether the RMC-1 is better than the XMC-1...maybe ask those who made that swap what they think - independent of the DIRAC detail you started with. Mark |

When you do find a processor(s) that utilizes DIRAC 3 @96khz, please do come back and let us know which processors(manufacturer/model) and what you paid for that processor, as I'll be interested to demo that processor to see if I can actually hear a difference. In the meantime, I guess I'll just have to suffer listening @48khz. |

It's a hardware limitation. A PC can do 192kHz and the Datasat can do 96kHz. Early on in development, Emotiva boasted about their hardware being overpowered, but things didn't turn out that way. Best they can do now is downplay >48kHz.

agree. Hardware is almost always the limitation. This is either because of ineffective coding or software architecture, or because the hardware isn't advanced enough for what software developers want it to do. Video cards are a good example. We've had the capability for a very long time to have life like CGI in gaming. The problem is that the hardware isn't capable of rendering that detail at 60FPS or better at higher resolutions. |

I know that statement has been out there for a while, but I'm pretty sure within the last couple years - it came out that the truth was "well, not really". And I believe that came from Dirac themselves also. I may be wrong, but I recall a heated discussion here and quotes directly from Dirac being shared. (Their statement might have been in context of the new version, not the old version in hte pre-Atmos world.) Mark |
