Zero latency is a marketing phrase. There will always be latency with a computer.

What is really meant: zero *relative* latency.

Technically yes, BUT (and this is HUGE) when that processing latency is less than the sample rate, there will be NO latency IN THE AUDIO PATH - this is what is important for audio processing.

Remember that computers process data at a rate MANY times faster than the audio sample rate, measured in GIGAHERTZ rather than kilohertz, which means they can make MANY calculations long before the audio path needs to see the next sample.

Hopefully I've explained this correctly - if not someone please correct me!

Actually its more of a data throughput issue than a computing issue, a USB bus can only transfer data so fast, memory can only copy data so fast.. There is DSP systems that actually work sample by sample or even bit by bit, without any latency, so its not really inherent with "digital" (if the OPs use of "computer" implied this). That said, audio in itself is tied to time

But obviously you're right with the core statement, the "problem" is ADDITIONAL latency, above the buffer size of the system and yes, CPUs are INCREDIBLY fast in terms of computing alone.

Possibly wrongly, I was assuming audio already in the digital domain - obviously getting analog audio in and out of a digital system DOES induce some amount of latency. But my point was related to how an internal process such as a plugin can be "zero latency" within the system.

OK - Hi everyone

Can someone please explain how and when to use this,, to a complete newbie! - In practical terms: say i used drums with kong put a synth line down with the stock plugs (should still all be zero lat) THEN I decide to use bass guitar or lead guitar using kussa rack extensions:

Once you know the latency time in milliseconds what do you do? do you go to preferences and change something there? so confused about this. Im luckily got a UAD Apollo 8p so vox coming in should be zero latency! and my studio monitors are zero latency as I'm mixing through an external analog desk. Just confused because I've never adjusted anything in terms of latency settings (wherever that is)

@Chrisdude: Unless you do use parallel processing (e.g. via parallel mix channels) the minimal latency differences don't really do anything bad, so don't have to care about this. But when you do use an RE with latency on a parallel mixer channel and you notice a comb filter like sound, then you've got a problem, where you should compensate for the latency introduced by the RE (unless you actually like the sound of the comb filter fx).

I agree with jam-s. It depends on what kind of Music style we are in and what we want to achieve exactly. The first time when a latency problem bothered me was with Polar while recording a melody. Knowing this i figured i could use a) Normen's device or b) just play the sequence dry and then add the particular effect after the recording session. The whole process with Music creation requires flexibility and workaround anyway.

Even when delay compensation is on, sometimes the plugin still creates a delay due to the nature of the effect.

Thats why TS-1 is great for realigning

Hello,
is there somewhere a list of Zero Latency Effect Devices (Stock and RE)?
or is there a list, how many latency any Device has?
Thanks a lot
Oliver

Is this still a big issue as Reason has PDC now, I don't think I have issues with it.

I guess if you are doing live audio or weird routing it can still be an issue though.

i got the VMG Sample Delay to Measure some things. after working a while with it, it seems that everybody who is interested in Latencys of a Device should get this, to test the devices everytime u need a latency compensation with that actual settings of that device.

but here is a small overview of the Devices i bought + that ones in "trial".

maybe i did something wrong?

the instrument section is a hell of a job... canceled

Wow! This was a lot of time and effort spent to help this community...THANK YOU SO MUCH!!!!

Here’s a question: since Reason has delay compensation now, why do we “care” about latency? I’m not trolling, this is a serious question. The most annoying part of Reason for me isn’t plug-in latency at all, but the inconsistent and incorrect timing of the EMI.

I’m going to start a thread about this issue, but wanted to thank you for the effort and ask why latency is important with delay compensation enabled in Reason.

I guess because a) It's only compensated between mixer channels, not in combinators or anywhere else and b) many people use Reason to play instruments live

Ok, that’s reasonable. Thanks for answering me!

Can you please add this :

Selig Leveler (look ahead activated) : 88 ms

Selig DeEsser (look ahead activated) 617 ms

I hope reason studios update a fix for this because it is causing me real headaches as is not even registered in Automatic delay compensation.

Posted: **29 Nov 2019**

On another note, Glitch RE produces phasing, even when bypassed, when applied to a parallel channel. Doesn't report latency.

Posted: **29 Nov 2019**

Another observations

Reason Needs to fix:

Reason Maximizer when 4ms look ahead is activated : 177 ms /current auto compensation : 176 is Wrong

Izope Ozone Maximizer when IRCII mode is activated : 2992 ms / current auto compensation 3014 is Wrong

i keep my sample rate at 256 is that good or bad??

It depends on what you are doing and your interface/soundcard.

Generally 256 is ok for low latency softsynth playing and for most cards somewhat on the (high side but if it aint bothering you, its not a problem).

If you are doing audio recording and want to hear plugins in realtime, this is what stresses the system the most and you would probably want as low settings you can get.

generally If you can get roundtrip under 10 ms, you are great.
