Upgrading license question 2.0 to X0

[Eric JH]

Hello!! I have a license for the 2.0 version 6.21. The convolution filters I made with Audiolense for Roon/HQ Player are game changing!!

In both the 2.0 and X0 product descriptions, it mentions optional time domain correction. I would like to ask if the time domain correction is the same in versions 2.0 and X0. And if it makes sense to upgrade to the latest versions or the functionality is basically the same.

I use a simple 2 channel system and have no intentions of changing the setup.

Please share your opinions.

Thank you!!

No it’s not the same. 2.0 «only» does frequency correction.

«Only» Imo this gets you 90% there. Sometimes more, sometimes less. But generally so much so that 2.0 users tend to describe the improvements the same way as the xo users. But it’s almost impossible to ignore the difference once you’ve heard it.

Thanks Bernt!

In my case, I use full range speakers so no crossover and minimal o no time domain issues over most of the audible frequency. In the low frequencies, I do use a subwoofer which I have put in the same distance arc as the full range speakers.

For non time domain corrections, does it make sense to upgrade to latest version of Audiolense? I have version 6.21 For time domain integration of subwoofer, maybe makes sense to consider version XO?

I will be writing an article on the implementation of Audiolense for my blog soon. I would appreciate your comments!

Saludos,
Eric

Hi Eric,

The time domain correction literally always improves the sound quality.

I read your mails about the article you're writing. Much appreciated! Feel free to post a link here when/if it goes on www.

Hi Bernt! Thanks for your answers! I did a series of new measurements last week. Will have a number of questions to ask you in order to write the best article. I think everyone should be using DSP/Convolution filters in their setups. Hope to share helpful information here too! Audiosensibilities Articles!
Thanks,
Eric

Hi Bernt! I have started to prepare the article on using AudioLense. I think it will be a combination of a tutorial/guide and a review. To start, I did a new measurement of the system. This was done, directly via USB to the DAC of the system. This way the measurement includes the complete audio chain + room. This is the measurement. Both the subwoofer and the main speakers were running. I chose the measurement with the highest correlation between channels. The subwoofer receives its signal via the amp speaker output.

From here we go to the correction target curve. Here I followed various recommendations which suggest to taper the low frequencies to not overwork the sub/speakers. For the high frequencies, the recommendations are to follow the high frequency response as close as possible to not affect the nature of its sound. Is it possible to limit the correction filter to not correct above say 10khz?

The main speakers are full range drivers in a horn loaded enclosure plus the subwoofer. Based also some online comments, I heard it might be possible to make the time window a little bigger is a lower filter sampling rate is used. For this reason I focused on making the convolution filters at 48khz. In the article I will also go into how to configure Roon and/or HQ Player to use the filters.

I have been using Audiolense 2.0 V6.21 would be a good idea to mention the updates/evolution of the software. Could you share these so I can include? I am sharing the impuse and group delay graphs. This for us to decide if you believe using the top end version of Audiolense would have time domain benefits.

The article will include a description of the measurement process, the design of the target curve, the correction curves and how to use them. I will get into the audible improvements, etc.

Please let me know if you have any additional suggestions.

Thank you!

Hi Eric,

I recommend a wider roundoff in the bass. A sharp corner can sound boomy.

Furthermore, most people prefer a downslope in the pssband. I usually end up 4-6 dB down at 10k vs 100Hz. But there are people who prefer a lot more … and others who prefer somewhat less. So this is worth some experimentation. There are a couple of tilt buttons in the target designer. Last, I recommend that you simply let the target continue straight out to the right, instead of tracing the tweeter as it starts to drop out. Audiolense hasa treble
boost limiter that kicks un when the tweeter drops … but not if the target traces the drop.

With Audiolense xo you can do a partial correction and stop the correction at any desired frequency. To do this around 10-20 kHz this is often slightly better than relying on the automatic treble boost limiter. And somerimes it makes sense to turn off the correction at a lower frequency.

Audiolense xo also has other tweak options that comes in handy, especially for horn rigs. And then of course the true time domain correction is included. It tends to improve clarity and precision.

Hi Bernt,

Thank you very much for the recommendations. I have implemented the wider roundoff in the bass, I used the tilt buttons and will listen to both targets. I also let the target continue straight out to the right. I did leave a little bump in the 10-15khz range. I could also take it out if you think it is best. I also noticed that you can move the target up and down. I lowered it in case that make it attenuate more areas vs boost them. Please let me know your opinion.

You are making a compelling argument to upgrade to Audiolense XO! How can we calculate the upgrade cost? Let me know what I should send you to do this.

Thank you!
Eric

Hi Eric,

You have just started, so it will only be the net difference. Send me a mail if you decide to upgrade. And I will send you a paypal invoice.

Thanks Bernt!

Will send you an email shortly.

I just published an interesting article on a great way to isolate your data network from your streaming audio.
