So, are You coding that? You know, maybe Martin Might consider adding that feature though. because it is popular. I think that's what i would do if I was some dsp genius.

Wow! - just did a real ear-opening experiment. For about ten years I did archival recordings for a few local groups, mostly chamber music and piano/vocal recitals. Most of them were in too-small and too-dry rooms. I'd experimented on and off for years, mostly with Apple's Maytrix Reverb, trying to make these recordings sound like they were done in larger halls, with mostly disappointing results.

I took one of these and applied the Concert Hall preset of MVerb 7,but cranked the Pre-Delay to max (so's not to overlap with the existing room sound in the recording) and - beautiful! :P Just amazing that a 'verb with such simple controls could do what that fancy Matrix Reverb with all it's complex controls could not (at least in my hands). Not a trace of that sproingy, ringy, metallic sound so common with digi-verbs. The biggest difference is in how natural and smooth the decay is. Kudos a-go-go Martin!

I'll try to extract a bit of A/B comparison and post it.

Here's a short clip. Classical chamber ensemble in hall with short decay time - dry first, followed by same clip with MVerb 7B; 'Concert Hall' preset with Pre-Delay set to max, and Width reduced a bit (actual halls rarely have reverb tails that are very wide in relation to the direct sound).

The difference is most apparent listened to on a real stereo system rather than a laptop.

Even more impressive is this clip of a full orchestra (violin concerto) recorded in an even drier hall (college auditorium); rehearsal of a community/volunteer orchestra. On both this and the clip in the previous post I had to apply a pretty heavy HiPass filter to the dry signal before processing with the reverb, or the resulting reverb tail got quite blubbery-sounding. An addition to MVerb 7B that I'd highly recommend would be an adjustable HiPass filter in addition to the 'Tone' control. There are many cases in which too much LF energy getting into the 'verb will result in a very muddy sound. It would be very handy to have this in the reverb, rather than having to do it as an additional step.

:D :D :D Martin - this thing has changed my life! In twenty years of making recordings of some quite good music in pretty 'unfortunate' acoustics, I'm finally able to actually enjoy listening to them. As well as I might have engineered many of them, the dead acoustics made listening to the resulting recordings quite un-enjoyable. As I mentioned before, I've tried many times over the years to ameliorate them with digital reverb and was never happy with the results, till now :P. MVerb, unlike almost all the others I've tried doesn't add a timbral 'color' to the reverb - it just sounds like it's supposed to. I've taken to calling it 'Kingsway Hall in a can' - those classical recording afcionados out there will know what high praise that is. :geek: :) .

Wait till I add haas. Or, maybe lala; We could just make that checkmark in haas. I could add some slider or something :roll: instead of the reverse.

I could code it in dsp and then maybe make it into asm whichever the case may be.

Isnt Haas just a pre-delay ?

Vintage mode could also be added which would just be a brickwall filter at 12k.
My favourite reverb ever is the EMT 246 and it has a sharp cutoff at 12k , never has that fizzy top end that is really never needed in reverbs.

As for the Reverse , in the impulse reverb you can just reverse the array , have not looked at how its possible in this particular delay.

True, true these are good ideas. Maybe even two or three features? Could be done without much work.

Does depend on what martin wants to do , like i said I added that switch for aesthetic reasons .

I still say the most useful addition to MVerb is an adjustable Hipass/LoCut filter (in the wet path before the reverb, obviously).

Like so:

MVerb7Bk_hp.fsm
(140.24 KiB) Downloaded 957 times

Especially for 'Concert Hall' type sounds, as the better real-world halls are noted for having less reverberation at low frequencies.
Using a simple Butterworth - Martin would probably choose another way. :)
At more drastic settings, can create some great icy sounds in the Gated mode.

The transition might seem more natural if You try My 1 stage nedf HP/LP; They're mods of MV's code and have a steeper curve than traditional trigonometry. Because the curve is a bit less steep; It might seem more natural and use less CPU because it is linear.

Yes, I've been playing with a haas effect using fractional delay because it uses less CPU and is linear. So far so good; And I've been working on a vocal processor that creates the effect of two channels with stereo width selectable and then furthermore the option of compressing and furthermore adding haas. I used Cytosonic's interesting method of avoiding the db to linear detectors because naturally they use a lot of CPU.

More on that tomorrow at any rate
