Hi
asio guard changes the sound even on mixdown. i tried to bounce one with it on and one with it off.
thats what chat gpt told me:
What does it tell you if you run and compare two passes done without ASIO guard?
good point will test tomorrow and report back. do most people work and even export with asio guard on?
Yes always on here.
for me with it on it makes everything sound a bit muddy somehow but will make your sugguested test tomorrow and will reply hereš
The only significant difference is in the null test and null test 101 is that you must also test two passes with same settings and if those null completely you actually confirmed there may be something to what youāre thinking. If they donāt (which is far more likely) you might well be making some wrong assumptions about why you got different results for different settings.

What did you do? Did you upload files and then ask questions?
Chatgpt and others arenāt really that great once the technical questions get deep.
For example, a ten dB difference is not necessarily audible if itās at the bottom, covered by other sound.

i did it because i can hear differences when exporting with or without asio guard activated. for me asio guard sounds a bit more muddier phasier
yep i uploaded it to newest chat gpt version and chatgpt analysed the files and did a null test
If you use Audio Mixdown Export then ASIO Guard is not active, as far as I know. It is for real time playback only.

As @Johnny_Moneto implies, asio guard is not needed for export/rendering, itās designed to reduce latency when recording .
if you try yourself exporting with and without asio guard donāt you also hear a subtle difference?
with setting it to ānormalā I think it doesnt make a difference but setting it to āhighā i definitld hear a difference
Are you sure you have eliminated any elements of randomness occuring in the song? E.g. an oscillator from a synth set to free/random phase? LFOs that donāt start exactly at the same phase position?

Make of this what you will. For myself, ASIO Guard is turned off - I donāt need it.
ASIO-Guard in Cubase is designed to reduce real-time latency during recording by pre-calculating upcoming audio blocks in the background, but it is not necessary for exporting, and can even introduce timing inaccuracies or delays in the export process. For a stable and accurate export, you should usually disable ASIO-Guard before performing an audio mixdown to prevent issues like clicks, pops, or timing problems.
What ASIO-Guard does:
- Reduces latency for recording:
It shifts processing from the strict real-time ASIO path to a less time-critical background path, allowing for lower latency during playback and recording.
- Uses pre-calculation:
ASIO-Guard pre-calculates upcoming audio blocks when thereās available CPU time, ensuring they are ready for the next ASIO block cycle.
- Dynamic reallocation:
It automatically removes monitor-enabled channels from its path, but channels return to the ASIO-Guard path once monitoring is disabled.
How ASIO-Guard can affect exporting:
- Timing issues:
When enabled for an offline export, ASIO-Guard can sometimes cause slight timing issues (like āflammingā in percussion) between virtual instruments.
- Unnecessary process:
It is not required for rendering and can interfere with the final audio output.
- Potential for instability:
In some Cubase versions or specific projects, ASIO-Guard has been reported to cause hangs or other issues during export, especially when using complex templates or certain third-party plugins.
Recommendation for Exporting:
- 1. Disable ASIO-Guard:
Before initiating an audio mixdown, go to Studio > Studio Setup > Audio System and uncheck the option to activate ASIO-Guard.
- 2. Increase buffer size (optional but helpful):
While not strictly related to ASIO-Guard, some users find it beneficial to also increase the ASIO buffer size before exporting, which can further improve export stability, according to this YouTube video.
- 3. Perform the export:
With ASIO-Guard off, perform your audio mixdown via File > Export > Audio Mixdown to get the most stable and accurate result.

I agree.
There is a manual. Why arenāt we using it?

I eagerly await the AI inevitable burnout.
My understanding of ASIO Guard is that it would only come into play during export if you are using outboard effects. This would be similar to recording live tracks in a tracking session along with synths or VSTs. I never export with live effects so itās a theory 
.
I searched around for official documents like manuals, or articles posted on steinbergās site, etc, but couldnāt find exactly a direct mention of asio-guard for the export.
Manual describe asio-guard as a playbck feature that pre-processes audio on a separate path. They donāt mention it applying to export.
Helpcenter explains that offline audio mixdown/freezin /render in place time depends on buffer size, which aligns with the theory that export is using the internal engine, not asio-guardās realtime safety path. It still doesnāt literally say asio-guard is ignored.
There is no official source stating clearly that the asio guard is ignored during export but reading from the manual and helpcenter I understand and can fairly conclude that it isnāt.
Maybe an official can enlighten us?
Why two exports are not the same:
- Effect plugins, especially those emulating analog equipment: are adding noise(s), the processing is non-linear
- Instruments, like eg. synths emulating analog hardware, will generate slightly different sound all the time
- Dithering, is a noise, thus by its nature itās random
tl;dr thereās tons of plugins that slightly randomize the sound, thus renders will never be 100% the same.
For those who already gave away thinking to AI nad who believe that itās omnipotent like a god, ask it this question:
āIām using plugins that emulate non-linear processing. Why my DAW audio renders never sound the same?ā
There needs to be.
Anyone who has read a few of my posts will know Iām something of a luddite.
