But sometimes i've found that I can go back to a reverb (or whatever) that i've previously discounted as crap, and find that actually it is perfect for certain uses.

You say you are into Ambiant music, where the reverb is very exposed and almost an instrument in itself. While not my prime interest, I can relate to those types of reverb. You say you like Freeverb - is that the Sinus Freeverb2? Sounds like filtered white noise to me - maybe I should try it again.

Seriously - have another look at Magalov reverb, because I think it is perfect for huge ambiant reverbs. Try with maximum high end damping, the largest room size and control the length with total damping. I got an amazing lush ambiant reverb by combining Kjaerhus Classic reverb with Magalov reverb. I used the Classic with maximum high end damping to get a smooth dark tail, and combined that with the Magalov for the high's - a bit of pre-day on the Magalov and it sounded richer than a huge Lexicon.

Something I look for in a VST reverb is good mono-compatability. Huge stereo tails are useless if they sound like crap on an AM radio. If you have PSP Easyverb for example - try mono'ing that. It doesn't have a width control, so you will have to use a mono plugin or stereo panner. I think you will find that the Hall is about the only algorithmn that doesn't sound wrong in mono. Magalov sounds smooth in stereo or mono - it has a width control that makes this easy to check.
Thanks for taking the time to give some advice. Perhaps I will give Magalov a second try using your recommendations. It just sounded a bit metallic for my purposes. I find that these type of reverbs often work very well for pop music styles but don't blend quite as well, IMO, with ambient type sounds. Again, it all comes down to taste.

I like the Kjaerhus Classic Reverb very much. I may be wrong but it seems to implement a variation of the Schroeder/Moorer algorithm that is used in Freeverb. My only problem with it is that it's hard to get a long decay/tail with it at the higher damping settings which I normally prefer. It seems that he has designed it more for pop styles of music. Other than that it is a very nice reverb as are all the Kjaerhus Classic Effects.

The other reverb that I like very much is the PSP EasyVerb. The Hall setting is very nice and reminds me very much of the Freeverb soud but with more flexibilty. I also tend not to use early reflection very much so these types of simpler reverbs suit me just fine. I agree with the observation that Jezar made, in his essay Thoughts on reverb, were he states that he also has a preference for the more artificial sounding reverbs, ie Lexicons and Quantecs, as opposed to those that try to model real environments in more scientific detail.

Anyway, thanks for the advice.

The Kjaerhus Classic Reverb is actually a prime recommendation in terms of the original post made.

It has a nice warm sound, a bevvy of useful and good presets, and - particularly important to the OP - very low CPU hit.

I use it most of the time for this very reason. (and it's free - why spend your hard-earned on another reverb when this one does the job so well?)

I'm discovering how wonderfully versatile and good sounding glaceverb is day by day. The GUI is kinda daft with that low-contrast tiny "LCD" thingmajig, but other than that it's the bees knees. You have a lot of options with absorption/texture/resonance controls and it can do a rather decent modulated "artificial" sound like some revered hw devices. It can do vast and dense plates, wet ambiances and ringing room/chambers alike, and CPU hit very low on my pc.

Oh, it's also free.

you guys checked out spinaudio roomverb m2? its not that high on cpu as far as i could see....

Reaktor 5's Spacemaster - truly superb reverb IMHO.
Easily the best I've used (well sonicly too my ears ateast (it only uses between 5-8% CPU on my system also).

Ableton Live's - built in reverbs as insert ambiences only -they work well in this context.

Glaceverbs DaSample - as an insert ambient special reverb effect (really does some great oddball ambience processing for little CPU overhead).

Reaktor's SpaceMaster - as a send/return based reverb effect - really nice reverb this it sounds lovely and clear with good frequency definition and no bottom end mud.

SMEX's Ambience -I like on the mastering strip once everything else is bounced down. It sucks the CPU juice but is very transparent with just a hint of send to a final mix for added space.


Those are the only 4 I use :oops: .
Smex's Ambience and Reaktor's SpaceMaster being the most seriously flexible of the lot however each has it's place depending on the context in which it's used.

@ John,
being into ambient, you've tried convolution with impulses other than room and hardware captures, haven't you?
i just love stuff one can get when using some oddball, created by hand stuff as an impulse.
i believe there is ready made impulse lib in such a vein, wait
from Spirit Canyon Audio.
btw, i find, that Revolverb is reasonable for CPU even on my prehistoric pc.

Yeah, I'm heavily into using convolution with non reverb type impulses. It's actually one of my favorite tricks for mutating musical and field recording/sound FX type sounds. Other than using impulses made from synthesized sounds, I do sometimes use "real world" impulses taken from small/unusual speakers or reverbs made from odd environments.

There are some very interesting impulses, along these lines, by a fellow named Fokke van Saane that can be found at: http://www.xs4all.nl/~fokkie/IR.htm

Anyone tried PSP pianoverb. I find on some things it works better than what else is about.

I'm curious as to why you recommend this reverb as an insert only? I quite like it and have actually been using it bit more lately. I've gotten in the habit of turning of all of the early reflection features as I really don't like that level of detail very much in the reverbs that I use.

I'm pleasantly surprised it got a mention here! :)

It's available at the auditorium..

Here's the initial version I had with a GUI..

Be careful with low absorption settings, it's still a beta..

I'm currently redesigning it as a synthmaker module (just as fast, 100x easier to develop..)
hey!

"The topic or post you requested does not exist"

and i can't find it via google either .. damn and i had to register to another board for nothing :P

Glaceverb is great and it's free (not donationware or similar). This is a VST plug-in, and it isn't heavy on CPU usage.

Unfortunately most convolutions are CPU heavy due to the calcualtions needed process each render. As CPU's get more powerful, this will diminish in priority.

In the meantime, you can use an impulse convolution as a send/return effect to save on resources.

Another vote for Wavearts Masterverb, I have Convoboy (registered) and SIR and I always go back to Masterverb for 90% of my works.

Sounds very good and is quite low on the CPU

Post

Anwida DX Reverber is very light on CPU usage, and has a great sound. Also, Sonitus that comes with SONAR 4 is pretty good, but DX sounds better to my ears...

Wk

Post

another shout for Glaceverb, great verb and even greater price.

Wow - this thread is suddenly back!

Must say that I'm looking forward to seeing, hearing, demo'ing the new Masterverb 5 when Wave Arts release it :hyper:
