It would be helpful to post images of all your correction procedure designer settings to diagnose the issue.

What frequency have you set the LPF on the sub to prior to measurements? A plot of the sub alone would be helpful. In addition, you may want to consider moving the sub around to get a better L/R channel balance.

This format works fine: 10.000, 2.5863540 765.414, 2.5863540 818.201, 2.5806000 870.988, 2.5519070 950.169, 2.4882810 1002.956, 2.4385290

I have overlaid the measured driver frequency response from Radian on the AL frequency response of your tweeter. You can clearly see where the in-room response of your tweeter is falling off relative to the near-field (maybe 1m) response measured by Radian. I would not have expected that big of...

Here is a result with much less insertion loss. I used partial correction to 13,000 Hz to relieve the tweeters. and a few other tweaks in CPD. Steve

Bernt, excellent tutorial on the use of partial correction. Question: I noticed that you left TTD Correction per Driver unchecked for this evaluation. Is there a connection between using partial correction and per driver TTD based upon the situation? Steve

In the Measurement Window, look under the Advanced Settings pull-down and you will see 'Use Clock Drift Correction' is checked. Audiolense detects whether you are using two different recording and playback devices and sets this value by default. It then performs the extra sweep to help correct...

I noted the same behavior. If you switch to 'Use sample measurement', the program will write out .wav files for the base sample rate.

@juicehifi The new resample filter is working well when I compare the magnitude of the .wav filters (96kHz and 192 kHz) to the correction filters. All curves match well. However, when I compare the phase of the resampled filters to the correction filters, I see differences as shown in the...

@Rsg11 Thanks, didn't quite understand the warning. It seems like the best solution after playing with this feature is just to write out correction filters with no upsampling (48kHz in my case) at the highest filter length available in the correction procedure designer (131072). I use HQPlayer...

@juicehifi I was trying to test out the new Resample Correction feature and am wondering what I may be doing wrong. When I select the output rate (96kHz or any other value), I get the error shown in the attached file. Steve

No problem. One filter file per channel. Are you considering a pair of 3-ways speaker with two subs? Exactly what I have done and can help you get started. Steve

I will try to help with your confusion. Both programs perform digital room correction, but operate differently. "Sound" does not get sent to Audiolense. Audiolense is used to generate correction filters which can be loaded into Roon or other programs which can perform convolution. There is no...
