Any alternatives to SIR, free ones please.

[Chickenman]

Only just d/loaded sir... after playing around with Waves IR1 the other day at my mates (which used half the cpu on a 2100xp at low latency.. even more for some of the big impulses) I've decided that Sir is as good if not better.

The only reason for wanting 0 latency would be to use preamp impulses? For reverbs and all that run sir in a send slot.. aint nothing wrong with a bit of predelay.

I still don't think it's that important, as someone already mentioned use a standard vst verb for tracking and change things over later.

hey sickle, I heard you praise Canyon IRs before and I'm at the website looking at it (been this way for the past week). The only thing holding me back is what exactly to use with them. SIR does have latency issues and I'm not willing to bust my wallet. What exactly do you use? and how?

[Sicklecell666]

I use Sir & reVOLVerb, but reVOLVerb doesn't run all of them very well, TBH. The Spektral Relativity IR's aren't traditional spaces by any means, so when I'm using em, I'm not really noticing the latency as the track most likely isn't 'structered' to begin with.

I tried the Pristine Space demo, & that would probably be my first choice among the IR readers, but theer's also Delay Dots to consider, & they partner with DBurgan, so maybe you wanna check that out as well.

As far as zero latency, I've pretty much incorporated the latency into the composition as that's probably easier than sitting around waiting for a zero-latency IR reader to get developed

One other thing you can do with it is load it into an audio editor like Audition, I'd imagine, where you can like has been mentioned before, apply garden variety verb to your track & replace it offline with SIR later..

Hope that helps,

Are there any other impulse Response reverbs, for pc that is free ? or do you know if that A no latency version of SIR is anyway near soon to be released, it feels like ages since it was announced, that Knufinke was working on one.

...

[CC4]

i was looking at FREE not impulse.

[dburgan]

Here's a list of all the convolvers I know of:

http://www.spiritcanyonaudio.com/convolvers.php

Of these, the only one that I know for certain has true zero latency is Pristine Space. I use it all the time, and it is indeed realtime, although it has a few notable constraints it puts on you. So, if you need realtime convolution, that's the one to go for.

There are others that offer very low latency, however. Waves IR-1 has a latency just a few milliseconds long, from what I understand. There may be others that are similarly free of latency.

Finally, TL Space from Trillium Lane Labs has zero or near-zero latency, when it's running on Pro Tools HD Accel. But that only helps you if you're a Digidesign shop.

Hope this helps ... !

anybody can download RevolVerb Lite Beta from the site ?

the link doesn't works for me.

if someone that has the file could send me the zip ? would be very appreciated thanks.

With PDC, there shouldn't be any delay unless it's on the track being recorded (in which case, it's impossible for PDC to do anything at all).

Please elaborate.

OK, premise 1: you are using a host that supports Plug-in Delay Compensation (PDC)

premise 2: SIR is NOT on a track that is being recorded in realtime.

Result:

Even before you press "record", your host is given information from the various plugins about how long their latency is. Let's say it is told that latency will be 8000 samples. When you press 'record', your host starts processing the audio, but doesn't actually spit anything out to your audio outputs until those 8000 samples have expired; ie. the calculations have been performed, and once you start hearing audio, you're hearing it as you will when the track is rendered.

Hence, latency is a non-issue. You can play realtime on another track, and only THAT track's latency will be an issue.

To the second point, about how zero latency realtime recording is impossible, regardless of PDC--

Premise 1: convolution is a mathematical process, and therefore your CPU has to calculate those maths.

Premise 2: it takes time, no matter how insiginificant, for a processor to calculate the maths.


So, when an impulse reverb is said to have "zero latency", in fact it's just really f---ing quick with the maths, using efficient algorithms and streaming the calculated data A.S.A.P.. So, 'zero latency' still depends on the processing power of your computer. I have no doubt that it can be done so that it's humanly impossible to tell that there is any latency, but zero isn't entirely accurate.

Now, just to be thorough, let me quickly explain how PDC doesn't help in real-time on the track you're recording: your computer is unable to predict the future. Therefore, it can't buffer 8000 samples... it can only start working on the signal when it is received. In non-realtime tracks, the plug-in is actually receiving the signal before you hear the audio (see explanation of PDC above). But in a realtime track, it can't receive the signal until you play it. Therefore, you play a note, and 8000 samples later, you will hear the results calculated through SIR. That's the only way it's possible.

Don't get me wrong-- I'm looking forward to the 'zero latency' version of SIR, and I DO acknowledge that when they say 'zero latency', for all intents and purposes, it IS. I'm just saying that in the meantime, I can't think of very many applications where it would be absolutely critical for me to even USE a zero-latency convolution. No doubt, CPU usage will go up in zero-latency versions, though I suspect that part of the reason for the long delay is that the programmer is streamlining ALL code in order to avoid a drastic CPU jump.

you can get it at the noisevault forum do a search if you have any amp cabs think about impulseing them 1n some position like on axis,off axis,edge,and,far and posting them there

didn't found it, but anyway, seems like "normal" that the file isn't on download anymore :

In a case of RevolVerb, the picture is different. If we normalise it's Delta file, we will hear strange boom-like sound on the left channel(I think this is a bug) and effect close to PS/SIR on the rignt one. Actually, to hear it you
can open any IR in RevolVerb and process 2sec blank/empty audio file, then normalize your result.

it is there do a search with this Channel Emulator Series look for this topic (Any feedback on the The Channel Emulator Series) scroll down about 8 post you cant miss it i just checked an it works

[drinelli]

This really did turn in to a great dicussion I just want to point out that I as I believe most people on this forum would agree upon, that true zero latency is a thing of the future. Did I hear a big "what", I will explain : some one said you can not look into the future, well but you can, if you got enough ram and processing power, and you have lets say a 100 keys on the keyboard, you can just calculate the whole lot of them in advance, or when Quantum Computers become the order of the day, they will calculate all posibillities at once, simple (not really) as that. But back to the subject, my problem with over 8000 samples latency may be an aesthetic problem, but to me it is very noticeable, and creativity is all about aesthetic in some way or another.

[Lunch Money]

It's definitely noticeable in realtime use. No argument there.

Interesting point about calculating all possible outcomes.

Thanks Greg, this also leads me to talk about, : why have no one ( to my knowledge ) made a sequenser, that pre calculate the vst plugins except for the record enabled ones. I don`t mean freeze, I mean something like a dynamic background task, that sees to that only needed plugins are realtime calculated, the rest is rendered to wave files, and when changes are made, just the nessecary parts is rerendered while you do other things. Also in away so that the resulting wave files, and their midi counterpart, can be edited in an linked and at the same time separate way, applying effects on the wave files, with the possibility of changing the midi data still remaining, "advanced offline history" if you know what I mean.
