HLConvolver 2.8.1 is released. HLConvolver is a headless convolution engine with a Web UI, systemd service integration, UPnP input/output support, managed ALSA routing, multichannel FIR processing, and optional DoP output. Current packages are available for Ubuntu 24.04, and Raspberry Pi arm64...

Your understanding is incorrect. Each Al customer at the end of the calibration process receives a 20 to 30 minute instructional video walkthrough using their own measurements showing "best practice" on how to get the best possible filter design that is repeatable. Further, I point out areas for...

Hi Bernt, I can confirm this release fixes the excess delay. Thank you!

HLC Web Application and HLC Embedded are two new additions to the Hang Loose DSP Software Suite, which is a growing suite of audio DSP applications and plugins. HLC Web Application and Embedded can run on Mac, Windows, Linux, and Raspberry Pi. HLC Web App can run with a native UI or run...

@Julcat Simply import the .pcm impulse into REW and all will be revealed :cool:

Hi Ofer, yes, I have been running AL under W11 for a couple of years with no issues. Same with HLC.

@vego99 from the Radian website: "The 950 driver delivers clean high frequency sound with ultra-low distortion. This reduction in 2nd and 3rd harmonic distortion is only possible with our large format 4" diaphragm, 5 slit phase plug and Mylar suspension." Key phrase: 5 slit phase plug. These...

Yes, these are constant directivity waveguides and as such requires constant directivity eq: https://sound-au.com/project173.htm My JBL waveguides (with the large format 4" compression driver) requires the same type of eq along with JBL M2's and other constant directivity waveguides. A good...

@Cornelis Huizinga and Arch's article on Multichannel Digital Room Correction with Audiolense XO.

@whoareyou it is hard to tell from your screen shot in the first post what the dB vertical division is? Also, probably more constructive to see the correction filters response... complete with vertical (1dB per div) and horizontal scales. Yes, AL will make up the gain difference. But if there...

@dima1stg there still appears to be some confusion... There is nothing wrong with REW. There is no timing instability. Period. And nothing to do with sample rate. The issue is 2 clocks (derived or otherwise) between the USB mic and audio interface. And as I said in the post above, it is not...

Perhaps there is a bit of confusion with the OP. First, I am not the author of Acourate, that would be Dr. Ulrich Brüggemann @UliBru here on the REW forum. 2nd there is no issue with UMIK-1 or 2 using the "Measuring with file playback" method as described in John's REW Making Measurements help...

Same issue here. Reported to Bernt.

@NMixes Jeffrey has you covered and congrats! It is a nice mic and one of the very few that publishes it's distortion profile. @yoav yes, this is the same answer and calibration file I also received a while back. Sorry I did not post it time when you asked your question.
