Title: Digital Correction for speaker/room sound interface
Post by: Robert on May 14, 2018, 02:15:25 am
I have read both reviews(loudspeakers and integrating subwoofers) of a European software package designed to time align speaker drivers and create a digital crossover to enhance the overall sound in the listening room/environment. By all accounts end result is very worthwhile.

This is on the Computer Audiophile home page. It is interesting reading and something worth experimenting with in my view.

Has anyone played with this kind of software on the Phasure forums?

Is it possible for this to work with XXhighend?

The room/speaker interface is critical in my view especially with small listening rooms and the myriad of furnishings, material makeup and other people sharing this space.

Hi Robert,

FWIW (!) : You are talking about the same forum where nobody hears a difference in anything, differences can't even exist while matters you refer to are crucial. Somehow.
To me this seems not to combine at all.

Anyway this is not new of course so maybe we are not talking about the same thing and (kind of) software.

If we look at this from a mere technical perspective and/but also in relation to hoe XXHighEnd achieves her goals (with many contributions of yourself) then all minute things happening in there will be thrown out with one big blast. So to give a virtual number : say that XXHE improves SQ by technical means with 0.1% then the means you are referring to will degrade SQ by 10%. IOW, you must completely forget that such software (also hardware) will be able to sustain the SQ you are used to and chose for yourself (by settings etc.). However :

It is one large mixed bag of apples and oranges because we are talking about completely different kinds of "sound improvement". I mean, say that XXHE is able to more accurately reproduce the music then what is it worth that the time alignment of two speaker drivers are so-so and can be improved upon by some means which debunks the usage of XXHE all right, but which is an improvement in itself. I mean, I did not compare ...
(but I even can't if we're talking about time alignment because my speakers have that inherently arranged for (it can only be destroyed).

There is so, so much more to say about this, ... undoable.
But an example for you could be that the Orelo MKII speakers makes used of DSP only for the bass (under 240Hz or so) because I explicitly only allowed it for that frequency range, which is all related to the sampling speed possible of such DSP hardware and how otherwise the higher frequencies would be destructive for our fine DACs to begin with. Or, how for example Dirac (possibly you refer to that) allows for a (recording) sampling rate of 192KHz max while your DAC already outputs 384 and mine 768) and while *also* not even more than 20KHz is output by that software. Conclusion of only the latter : forget Hires.

Only pure in-software (which Dirac is too) solutions have a theoretical chance (because there's actually no sampling rate in order), but the first thing that incurs for is a D/A converter per channel. So if you have two speakers and Bass + Mid/High then this is 4 D/A channels (and 4 amplifiers). You have Bass + Mid + High ? then 6.

The (preliminary ?) conclusion is that you can only make it worse with relatively low money and with high money there isn't even a good solution (but it could be made - even by yourself with creativity - don't ask as I am not that creative, haha).

Dirac would be the only one which works with XXHighEnd and the sound is ... .... .
(I tried it).
Maybe my standards are too high ?

Kind regards,
Peter

Yes everyday there is less of interest to me on the forums and more even stranger polls keep appearing. What they do with the information is about as good as a political poll, nothing worth while.

Anyway I get your comments. I was interested in your thoughts on this subject. Thanks for that.

Robert

Robert, may I ask, what software did you have in mind ?
And I don't want to prevent you from trying anything. My thoughts you have, but now what's next ?

Best regards,
Peter

Audiolense is the software. The reviewer seems to have got it working but with J River. The concept is a good one but probably still needs more work. I,m currently reading up on it. I,m looking at trying it with a spare HD which has current W10 on it and Spotify,  Netflix etc. As I run sub woofers it may help with the integration of them. But my room has several problems and this is where I would like to improve the sound.
