Acon Digital Verberate - New realistic algorithmic reverb

[bsork]

Thanks for reporting the issue. I see we're almost neighbours, by the way (I live close to Røa). I wasn't even aware of Usine Hollyhook, but I'll check it out with the debugger. These issues all seem related to lacking multichannel support or strange block sizes in the host. FL Studio seems to change block sizes randomly in the range 1(!!!) to around 200 samples - very strange behaviour, indeed...

Well, I was an extra bit curious about this reverb because it's Norwegian...

I haven't had the time to do any testing at home of the 64-bit version, but I did another test with the old pre-Hollyhock Usine (v5.80), and it showed around 10% less CPU. I'm fairly certain that the meter in the two otherwise quite different versions measure the same thing.

What I didn't notice yesterday is that there are eight outputs - presumably for surround(?). I reckon that accounts for the high CPU usage - do you plan on a stereo version?. Usine has no problems with multichannel - both old and new versions handle up to 64 outputs, IIRC. There are also no varying block sizes in use.

I'll try do to some more testing at home sometime during the weekend.

There will be a two channel and a multichannel version available (with different prices - $99.90 for the stereo version and $199.90 for the surround capable version). The license key for the surround version will work for both. The host should report how many inputs are in use and how the speaker arrangement is. If it doesn't, there is no way that Verberate can process multichannel audio correctly. Many host don't do this correctly and always use all eight inputs (with a zero signal fed into the remaining six channels in a stereo setup). That causes the CPU load to increase unnecessarily for obvious reasons. I didn't get to check Usine with the debugger, so Verberate might also be the culprit in that particular case, though. Regarding the alternating block sizes, there is an error in the 0.9.7 release that causes the fast convolution engine used for the early reflections to re-partition every time the block size is changed. Fixing that will solve the extreme CPU usage in FL Studio, but the performance will always be better when the host behaves...

Cool, will give the demo/beta a test spin as soon as possible, and when I end up with some nice examples, I will send them your way, stian!

Thanks a lot, I look forward to it!

Stian thanks for your response in the other thread. The reverb seems completely unusable in my older version of Sonar wich is version 8.5 and using my Logitech Skype headphones to test. Soon as i launch the reverb there is a very loud noise that overloads my headphones and this noise continues to happen as i change presets. I can hear the reverb at times but the moment i change parameters the loud overload noise returns. It appears highly unstable in Sonar 8.5. I have not tested it in my newer version Sonar X2 using my SCOPE XITE-1 soundcard and Event Studio Precision 8 monitors but feel it should've worked in the set-up i used wich normally does work with compatible plugins. I don't want to gamble and ruin my main monitors so i'll wait until you investigate and have solution. Like i said before Sonar can be fussy and in my experience new plugins sometimes take longer to get fully stable in Sonar than other DAW's.

Oh, that's a pity, but thanks for the feedback anyway. I'll investigate and hopefully get it fixed quickly.

Hi!

Thanks to everybody for your valuable feedback so far. I have now uploaded beta version 0.9.9:
http://acondigital.com/software/beta/Ve ... _0_9_9.exe
http://acondigital.com/software/beta/Ve ... _0_9_9.exe
http://acondigital.com/software/beta/Ve ... 9.mpkg.zip

Changelog

• Toggle buttons for the Dry, Reverb and ER sections
• Linear movements for the knobs
• Reduced or eliminated "zipper" noise when changing parameter settings
• Fixed: User settings in the preset root folder (no category) not shown in user preset sub-menu.
• The "Lock dry and reverb levels" toggle is now persistent
• Fixed re-partitioning issue in FL Studio. The CPU use in FL Studio is now acceptable, but not great. Check the "Use fixed buffer size" option in the Wrapper in FL to achieve better performance.
• The plug-in is now 2-channel stereo only. A separate "Verberate Surround" will follow.
• Last but not least, replacing the C++11 features was easier than expected. It now compiles with the 10.6 compatibility flag on and I have removed the restriction from the installer. I haven't set up a test system with 10.6, so I would be very glad if somebody could provide feedback regarding the compatibility here.

Maybe Theo will be interested in that last point ...

Installs just fine as AU in finicky Digital Performer 7.24, Mac OS 10.6.8.

Seems to be an interesting and easy-to-tweak verb for creating 'room' and ambience around e.g. rhythm guitar (just a quick test).

Will dig deeper as time permits, but definitely a heads up in the crowd of reverb processors!

Thank you very much for testing! It's great to hear that it seems to work with 10.6.8 and that you like the audio quality!

The latest changelog looks nice, Stian! I can't wait to start playing with it!

I'm going to install it later today and let you know my findings!

Working now in FL. 15% CPU on my I7 2Ghz

Sounds nice. Any idea how much it will cost?

Cheers

Thanks for sharing your findings, David! 15% on an i7 is still much higher than on other hosts, I'm afraid, but varying block sizes combined with zero-latency is quite a challenge... There will be a two channel version available for $99.90 and a surround capable version for $199.90.

This is a serious, bona fide question (not any sort of trolling):

Since I already own Virsyn REFLECT, EAReverb, Arts Acoustic Reverb, Exponential Audio Phoenix, Valhalla Room (and Vintage ditto), SKNote Verbtone, Rev250 and Stagespace, and Relab LX480 Complete - what flavours would you say that Verberate could provide, or excel at, that are not easily attainable with the ones listed above?

Or, in other words, what sets Verberate apart from the crowd?

Best regards,

Joachim

Wow, that is indeed an impressive list...

...what flavours would you say that Verberate could provide, or excel at, that are not easily attainable with the ones listed above?
Or, in other words, what sets Verberate apart from the crowd?

One aspect that sets it apart from the competition, in my opinion, is the ability to simulate large spaces without graininess or coloration. The early reflection processor also does a good job of placing a room around the audio source without unpleasant comb-like effects, although hybrid algorithms such as REFLECT also excel at this.
