I thought from the picures that the mic position is easy to change via mouse to create different room setups. But seems just a lot of fixed presets. This is the only reason I see to not used just impulse response reverb. Do I miss something?

Yes, you have no control over those mic positions even though it looks like you have. When you click anywhere on that panel under 'Reverb Model' it just brings up the Preset menu.midi_transmission wrote: Mon Oct 19, 2020 11:14 am I thought from the picures that the mic position is easy to change via mouse to create different room setups.

I'm not sure why they imposed such a hard limitation over it - although these type of generating IR reverbs have a lot of useless settings, seems they wanted to avoid that.

But what is the point to use these algo created reverbs then? I could just use a good collecion of impulse responses?

It reeks of false advertising. Although tbf nowhere in their copy does it say you can manipulate those positions manually the UI really makes it look like you can.

they're tweaked and paired to work well with the other part of the reverb that's purely algorithmicmidi_transmission wrote: Mon Oct 19, 2020 11:37 am But what is the point to use these algo created reverbs then? I could just use a good collecion of impulse responses?
I think there's a lot of similarities in operation to Voxengo Spatifier that's convolution but creates them on the fly as well. It's different as just using IR's

I'm not exited anymore because of this, I do not see the benefit currently of this reverb compared to impulse responses. Maybe I still miss the point?WatchTheGuitar wrote: Mon Oct 19, 2020 11:39 am It reeks of false advertising.

But I feel the need to defend d16, it's not false advertising. As you said, it's not said anywere that you can do it. And in any case it's a helpful information about the setup you hear.

Spacerek has a lot more flexibility for positioning sound sources within a space than a traditional convolution reverb. With an impulse response you can't change the volume and panning of the direct signal, early reflections and late reflections separately. They are all fused together with an IR. You could use separate IRs for early reflections and late reverb, which would allow for more control, but getting separate IRs to gel together naturally can be a struggle. Another advantage of Spacerek is the addition of the direct signal control. This adds the delay of the sound source in traveling to the mic and being able to control the level and panning of this separately offers fine control over localization.midi_transmission wrote: Mon Oct 19, 2020 12:31 pm I do not see the benefit currently of this reverb compared to impulse responses.
At first I was very disappointed by the inability to change the speaker and microphone positions within the rooms in Spacerek, but after spending some time with the direct, early and late interactions I'm finding that they offer excellent control over spatial positioning and am getting very natural and realistic results. I love the simple, straightforward workflow and I think D16 did an awesome job with this, in spite of the frustrating restrictions on speaker and mic placement.

very helpful, thanks eco2slo
I'm still not sure about how beneficial I find this compared to good impulses, but I will give it a try.

Just did that. Soundwise Miles ahead imO. I compared with some Lexicon and Quantum - which I really like. But Spacerek is way smoother, very "gentle" and the Impact on the 3D Image is very interesting, too (try it with a soft Pad Sound).midi_transmission wrote: Mon Oct 19, 2020 2:57 pm very helpful, thanks eco2slo

Reverbation is not my Topic, but this one is interesting. It soaked the Harshnes out of my Sample Pads and improved the overall Sound somehow. I´ll examine that now
Test with Drums: too big but impressing.

It's true. A lot of settings sounds great and 3d.
One thing were I'm not so sure about is a tendency that early reflections sound too much like a slap delay for a couple of sound settings. Sounds a bit artificial, even for a very reflective room.Take some acoustic drums with "Big Cube Hall S1 M3 L-R (the lowest Big Cube Hall)" with loud early reflections.
The "Cathedral" sounds also strange to me. Nothing like a real room and more than a delay with a reverb combined. For some sounds this setting sounded very wrong to me, but for a guitar it sounded very interesting.
Or the 'Warehouse' sounds more like a delay with acustic drums to me. The problem is that you can't control the delay time and due to this the groove sounds off.
In general I seems not to like how the bigger rooms behave, they sound artificial to me.
Some other reverb settings, especially the small rooms, are almost free of this slap delay and the reverb of them sounds quite fantastic. Certainly, it's also biased by personal taste.
Interesting plugin for sure, but I feel it could be much more interesting with more control about the virtual rooms and a more natural tone for the big rooms. The idea and interface is refreshing.
Thinking about to buy it anyhow because of the good parts.

Yes, some of the early reflections are a bit too transient-heavy. It's a nice obvious effect more than an accurate room presentation. Generally, I was more impressed by the small to mid size rooms as well. Those sound very nice.
Ah, difficult. I've been comparing it to Eareverb 2, Aether and B2, and it's got its own character, plus it's easy to set up. Those three can do "big" much better though.
