I too have been testing the beta version (on Mac). Development is happening, a few bugs to squash but mostly looking really good. I've used it in Mitch's standalone host and also as an AU/VST type plugin.

Hang Loose Convolver multichannel version 1.0.1.3 is now available for download at https://accuratesound.ca (Mac and Windows), which includes an updated Operations Guide.

Details and video: https://audiophilestyle.com/ca/bits...ches-multichannel-hang-loose-convolver-r1140/

Thanks to the Beta testers here that really helped me out. Much appreciated!
So am I right in understanding that HLC MCH running on a Mac will allow you run AudioLense filters that were generated on a Windows machine ?

They work fine :), though as the filters are being measured/created on one machine and replayed on another you may have to tweak the .cfg file to re-direct the audio to the correct output.

If I understand you correctl, yes I’m developing Audiolense filters FIRs for multiple systems …. Saving them in Roon file format and handing them to Hang Loose convolver on my Mac Mini … works awesome !!
Mitch’s program is awesome for gain matching and no delay in switching filters

I've had an issue recently and wondering if anyone else has or perhaps thoughts on a solution. When using Element to route my signal I have audio passing through to my Okto Dac8Pro without connecting any plugins in the chain. It is routing L&R into ALL of my drivers full frequency 20-20K. If I connect the plugins to input I get a echoic affect as the individual driver and speaker delays kick in as well as the lag from DSP filters.

I've done everything I could think of, then I wiped the drive in my M1 Mini and did a clean install and upgrade to Ventura 13.1 from Monty which I had been using. I did not do a Time Machine restore, I downloaded all the most current versions of the apps I use and installed them fresh. Very frustrating to go through that effort and end up with the same problem!

Apps I'm using in conjunction:
  • Roon or Apple Music - any source suffers the same problem - I'm not using any of the DSP functionality of Roon.
  • Loopback or Blackhole - I've tried using them individually (one installed and not the other), un-installing ACE - same issue
  • SoundSource - doesn't matter if I use it to direct signal or not - same issue

However, in SoundSource Element shows up as another app that SoundSource can direct which I don't remember being the case before my problem started.

If I mute Element in SoundSource I lose my right channel?!?!

Fortunately, I do have a work around. If I use Mitch's HLConvolverHost app along with HLC (which I normally use as an AU plugin within Element anyway for XO duties) I can route music to individual drivers just fine. However SoundSource is limited in its ability to host other plugins and so is HLConvolverHost so I lose out on some of my delays, most noticeably with subs.

Curiously, HLConvolverHost also shows up in SoundSource as a manageable app and if I mute it I once again lose my right channel. Audio Midi Setup also shows up in SoundSource but only on if I do a test signal on channel 1 or 2. If I have HLC muted losing the right channel but then test channel routing in Audio Midi I still get a test signal loud and clear on those muted channels?!

Before I did the nuke and pave procedure on OS Montgomery I tried going back to earlier versions of Element and also the beta. Now that I've done the OS upgrade I can't revert to earlier versions of the Rogue Amoeba software or their ACE driver.

I've been using Macs for 30 years and doing computer audio with active XOs and DSP for 15 of them so pretty confident my Audio Midi setup is in proper shape. I'm at my wits end on this. Any thoughts? I'm inclined to think it's an interaction between SoundSource and Element showing up in the managed apps part of SoundSource but am unclear why it doesn't affect HLConvolverHost the same way.

I quit using Element on my M1 Mac mini as it has not been updated for a long time now and is no longer being developed. I use REAPER as a multichannel VST host and it works fantastic. I use TouchOSC on an iPad with ReaLearn in REAPER to "remote control" REAPER and my VST plugins in realtime. I am using the HL Convolver VST3 plugin.

Hi Mitch,
Is this for MacOS only or for Windows too? Do current owners can upgrade or is it upgraded OTA?

Hi Ofer, Mac, Windows and Linux. Free upgrade by manually downloading and installing.
Hi Mitch

It says Ubuntu is coming soon.

Also can I use one purchased license on a few machines? Obviously not at the same time

Hi Mitch,

What is the lowest latency possible with your convolver and 4th order crossovers running at 192khz? Have you been able to achieve sync with YouTube videos?

If you are interested in a Linux build, please send me an email.

The license is good for 6 activation on one or more computers.

The convolver is 0ms latency. If using a minimum phase digital XO and mininum phase correction, like what is possible in Audiolense, then a 65,536 tap filter will work very well with YouTube or any other app/browser. Here is a Dolby Atmos example to show what is possible. FIR filters designed in Audiolense.

Good to hear. Do you have any idea of the latency in MS in that scenario? For example the Trinnov MC-Pro can work at it’s best settings with 15ms latency. What I have in mind is making a headless Trinnov MC-Pro alternative using the Linux version of HLC. But I will need to have the audio pass through it with little enough latency to not lose lip sync with video sources.

@MNSMike Julian's overall delay from the Atmos link I posted above is 4ms for his setup. In your case, the only way to find out is to prototype and measure as there are many variables in the equation.

Sounds good. We will start with the Windows version. Once all figured out I’ll hit you up on the Linux version. We have technology to clock sync linux PC’s with the entire audio chain. So the only thing that matters is latency. Clock drift over time won’t be an issue.

So kind of 'stating the obvious' question. After installing the new version three new dials appeared, see below. At their default position is it like before the upgrade? i.e. like not having them at all?
