Revalver 4 Latency Issue

[johnny M]

Hello all. I am playing with the demo before purchase, and using a Presonus Audiobox as an input. The manual recommends a latency of roughly 5 seconds. When I go in to adjust, I can only get down to a 10 seconds ( or is that 1 second vs .5 second?). In any event, does anyone know if you are locked out of ideal latency time in the demo, as the latency here is noticable. Will I be able to get a better latency with the full/paid for version?. Thanks for any help. I downloaded the 64 bit demo. Will 32 bit help w/ latency issue? Thanks again. John

The latency usually has to do with your audio interface and not so much with the software.

I have Audiobox and set it to 64 samples in ReValver about 1.5ms
No different in the Demo

I wonder if it's the computer, although it's brand new. I'm using Audiobox 22VSL. The only sample rate option is 44100 in revalver, and 441 Samples ( 10ms, is the lowest latency I can achieve.

I don't have an Audiobox but there has to be some kind of control panel.

If you are on Windows: Startmenu -> Programs -> Presonus -> ...? maybe?
You could also try in Revalver: File -> Audio and Midi Devices -> Device's Control Panel

Because you have to set the buffer size in the presonus software, not in revalver.

Lower buffer size = Lower latency.

However, if you set the buffer size too low you might experience cracks and pops in the sound or no sound at all.
So you have to find the correct setting.

Hope that helps.

I wouldn't worry too much about 10ms latency. Yes, towards 5ms is preferred but if your audio interface can't do it, so be it, just accept it and move on .

It has nothing to do with software or 32bit/64bit. Just the audio settings of your audio interface / Revalver audio-settings.

USB devices can't really go lower than +/- 9ms in 44.100hz anyway. Some report their latency lower.. but it isn't .

Setting it to higher sampling rate might help with latency, but doesn't always, and can bring other issues (like cpu issues or bugs , stuff like that) to the table.


How ASIO works (the audio thing Revalver uses under Windows) is that you need to setup your audio interface with the software that came with it (a settings app somewhere, is different with every brand). Revalver then uses the settings in that app. That is why you can't select anything other than 44.100 I think, because the settings-app of your audio interface is set to 44.100. Just a thought.

Set buffer size / latency as low as you can get it. But if you get 'stutters' or 'crackles' in the audio, increase your buffer / latency bit by bit until the sound is OK.

Around +/- 10ms is normal for USB audio interfaces with 44.100hz. (Focusrite 2i2, Focusrite 2i4, Behringer UR22 all have this as their lowest latency. I measured them). Some improve at higher sampling rates (96.000hz), some don't. Don't bother, it is fine.

Usually get some lag sometimes then remember to set my laptop to performance mode (i.e. System Properties > Advanced > Settings > Adjust for Best Performance)

In real world settings sound engineers usually gauge 1 ms as equivalent to 1 ft. On this basis 10 milliseconds is like having your real world amp 10 feet away - a normal sort of real world scenario isn't it ?
20 feet away is pretty normal too and was fairly usual when I used to rehearse at volume with a 100 W Marshall stack. I never even noticed the 20 ms delay - the mere concept of the physics behind it never entered my head !
It amazes me that as technology has become more advanced we musicians (myself included) have become obsessed with minuscule details when we should really just get on with it and play !
Stand back and crank it up - those were the days - along with ears that whistled for half a week after !

A thought - zero latency would equate to a real world scenario of having an amp inside your head, an interesting concept which brings me to the question of where the input socket might be located !

ah yes, wells said, in the future will be able to plug a guitar into our ears and wonder about the nanosecond it takes to tickle ones tibular

And you just put the data of your favourite guitarist into your brain and then you can play like them!
