Audio Correction

[Zina Perko]

I would like to share with you a young company providing with high quality room audio correction available on Roon.
This is HomeAudioFidelity:
You will find more details about the technology embedded in this solution.

From my point of view, this is the best solution I have implemented so far. Previously I was doing my own corrections using Rew and Rephase but with this solution the results are far more efficient with a very nice soundstage, deep, large and coherent.

It seems that the website navigation is a bit confusing depending on the support used to browse it.
Anyway please find hereafter the links to directly access the page.

A good feedback from a use on Computer Audiophile
Computer Audiophile New loudspeakers & room digital correction service4 minutes ago, fresponse said: It would be interesting to have measurements of your loudspeakers because I have never seen pure linear phase ones. I might be able to provide that to you for free. What types of measurements with what sort of hardware...

Interesting approach. I read the technology page and the comments about constant directivity reminded me of a paper written in 1971 by Ted Jordan (published in Wireless World) where he argued much the same thing.

I had previously used home made REW/Rephase filters, there were comparable with Dirac to my ears (but I had tried Dirac some months ago so I might be wrong). I am pretty convinced the HAF filters outperform Dirac in my case, but in order to be sure I have re-downloaded Dirac and plan to run a face to face against HAF filters. This I cannot do fairly in Roon as there is no way to use the Devialet Air driver (by far the best connection to the Devialet) with Dirac . My setup for the test will be :

This is probably beyond the scope of the home audio fidelity filter creation discussion, but yes you need to disable any other DSP to make measurements regardless how you do it, but in this example REW is the only player active.

"Regarding DSD, there is no convolution possibility on such raw format : all players usually convert to PCM & apply filters at high sampling rate (I have created filters at 384 kHz for HQplayer for instance)

Is there anyone that could please tell me how to disable the Bang & Olufsen audio correction? I'm sure that some people would love it but I work with audio and I really can't stand the way it changes the sound. I tried opening the Bang & Olufsen control panel but I can't deselect the correction in the "listening experience" section nor can I change the related equalization. Please someone help, thanks!

Please use the following and create a case for your issue and contact HP. If you live outside the US/Canada, please click the link below to get the contact information for your region.

Well I worked around it for a bit: I uninstalled the official driver and installed the general Realtek HD driver from the website, also apparently if you unplug your headphones (which to me makes NO sense at all. cause in a worse case scenario you'd have to correct the laptop speakers, not the headphones) you have the ability to change the correction on/off and change the levels and presets. For a period of time it remained froze as when I plug headphones on the "movie" settings but disabled. It was amazing to be able to work on music and listen to it normally even without the ASIO drivers. Now it's back to having that problem and as a producer I'd really hate that manufacturers do this because making audio sound right on all system would basically be impossible. I hope its just a bug of few people because it's not even an enjoyable correction, it even cuts the low frequencies ("the bass") which is what usually everyone wants to hear the most. But I noticed the HP suggestion now to actually contact them about this, so I'll give that a try hoping they can fix it (and hoping that they send a patch to all Omen or Bang & Olufsen users because this version is really sad right now lol). I'll let you know unless I forget

If I uninstall the driver all together I get an awful quality wiht no bass, if I install the generic realtek drivers B&O comes back! So is there maybe another unofficial why (registry maybe) to disable audio enhancements in windows?

I'm having the same issue. Bang & Olufsen is blocking the enhancements tab in sound speaker properties and can't turn off the auto enhancements equalization. When i play music the volume keeps changing up and down on it's own during play back. I had to disable the realtek Driver and switch it to Microsoft HD audio driver. The main reason I bought my HP Envy 750-124 is because it's suppose to have very good sound quality Bang & Olufsen. So frustrating

In video production, especially wedding filmmaking, there is one universal truth: Bad audio will destroy a good video. This has been a fundamental tenet of my teaching for years. Poor audio is a distraction that the eye cannot remedy. I put a tremendous amount of importance on dialogue quality in my films and it shows, and people do notice it. Dialogue, when mixed with music, creates emotion. When that dialogue is poorly presented it detracts from the experience you are trying to create for the viewer. Here are some simple ways to address common audio issues that can plague your production.

I'm feeling kind of like a three-legged race horse because I am using OS X. I've wanted to implement room correction since before I could walk (again). But the options seem kind of limited. In case I have overlooked something, or, more importantly, for others, let's create a running list of what options are available.

(If anyone has used windows to make a plugin or convolver that can then be run on OS X, that is fine too, but I'd like to limit that to what works in practice as opposed to what sounds like it might be plausible in theory.)

For this option, how do you produce the AU plug-in? I have yet to find a single example, and have spent a lot of time looking. (I understand that you can use the output to program the miniDSP, but it isn't at all clear that anyone has managed to do this for OS X itself instead.)

REW isn't exactly Room Correction software. It is software for measuring your system from a microphone. REW will plot the data your microphone records. You must analyze the data and EQ as appropriate for room correction. Dirac and Audyssey are automatic, this is not.

One would have to use either a) an external hardware EQ; b) software/boxes such as miniDSP which hook up with REW and can use the biquads; or c) Software that EQs the output of your computer, ie. iTunes' built in EQ.

REW does not give you suggestions for what to do for the room correction, except for in the form of biquads (which are a way of representing the EQ necessary via a numerical system that can be read by some EQ software). Using REW takes a long time and significant testing/retesting of your work.

You must be able to interpret the frequency response and similar graphs or this will not work. The benefit, of course, is that it is free, and you can post on the forums of their website for help. However, If you can not interpret frequency response, decay plots, or anything similar, then you should not use REW.
