No DLBC announcements?
How many subs are supported in the beta version?
Hi there.
Some updates from my end. For office system...
TL;TR; incredible improvement for my office system
1. Low end much better controlled, less edginess and resonances, room gain gone... very very focused and tight...
2. Mains do better job in upper bass and lower midrange, after reducing bass output (Bass Control basically is an Active Cross Over to mains as well), so THD do not leak from lows to upper bass and lower midrange... I can catch difference by ear.
3. Phase is controlled better - leads to as well to cleaner/smoother transition from sub to mains ( I do not hear sub as sub at all... it's like mains are playing...) and better phase control leads to smoother bass across sub frequencies... I will check BC: Complete next week, for now it is only Upmix
System:
AMP: Aiyima A07 with changed OpAmp/updated power (about CD quality SINAD)
Sony SSCS5 (quite good with EQ for table system)
Sub: SVS SB1000PRO (fine 300W sub)
Virtual Multichannel DAC: Hidizs S9Pro + Apple Dongle USB C (SINAD about -110DB for both)
1. Requested via Support access for Bass Control (a couple weeks ago), Installed beta and activated Dirac Live Processor with my account, where Bass Control became available (see instruction below)
2. Measured only today, had to travel for a couple weeks. No problem with Dirac Live Suite, works as expected. Figured out Cross Over, Phase, impulse response, Target Curve etc...
3. I used virtual multichannel DAC for now only with one sub (I have spare second sub, will measure probably with 2 subs next week). I'm using Loopback app for Mac OS, with two different DAC (Hidizs S9Pro for mains and Apple Dongle USB C for Sub, cheap and clean, left overs from headphones...). In loopback I create 4 channels in Pass-Thru device, create Channels 1 2 3 4 for output and route these to monitors, with target DACs (for now for one sub I use only one channel, which I understand is mono that will be passed by Dirac Live Processor)

Then I selected Custom Channel Setup in Dirac Live Processor

Then I add Sub and select Channel 3 as Sub Output (next week will add second sub)

And we ready to calibrate...
These are some results, which are not to shabby...
After measurements, I exported filter and got 3 channels in Processor displaying in level meter, and Loopback demonstrated 3 channel working...
One issue that I faced, I could not use Bass Control Complete, only UpMix... probably requires two sub at least? will check it later.

p.s. Will post on 2 Subs update later.
p.p.s. Managed to enable BC: Complete.
Left gain : -0.7 dB
Left delay : 8.2 ms
Right gain : 0.0 dB
Right delay : 8.4 ms
Subwoofer gain : -0.4 dB
Subwoofer delay : 0.0 ms
Subwoofer gain : -2.6 dB
Subwoofer delay : 1.5 ms
Any reason why you are using two DACs for the subs?A short update.
Measured with 2 Subs, added second DAC for the sub, simplified wire routing (with Amazon Basics Headphone jack to RCA cable for both subs).
With second sub sound became somewhat more simple to consume? Less pressure from bass? Difficult to explain, it was already incredible imaging and bass to midrange transition, now it is more natural/easy to consume (less pressure on subs to produce what they cannot produce I guess).
Deep in 45Hz is my office table, tried multiple subs positions, no help...

Interestingly, one of the subs (left sub) became time reference for the system. BTW two subs with different performance and manufacturer (SVS and ELAC subs, leftovers from systems from the past).
Only cable management, I did not like that my RCA cables been connected with oneAny reason why you are using two DACs for the subs?
Can't you just map two channels (3&4) into one monitoring channel as a mono signal?
Do you have any measurements of before/after the correction? Not an image of Dirac's hypothetical/fantasy corrected response.DLBC figured it all out and got it right.

This is how the result looks in REW (pink periodic), with Dirac enabled:

This is a pretty good match for my target curve.
Without Dirac it looks like this:

Sorry, I can’t show any impulse response graphs atm, I’ve been forbidden to run any further sweeps tonight

Dirac’s default curve is like -6 dB max.Good point. Just looked at dB levels.. 30 dB of steepness....
Is it target curve in DLBC with -10...-20...-30 dB trend line?
Dirac’s default curve is like -6 dB max.
Well, kind of yes and no... if you save target curve into file, you can edit it with any dB levels (using simple text editor) and later load it back.

did you forgot to turn on the speakers? because that slope is STEEP.
1. What speakers?
2. What sub?
3. How many subs?
