cubasis 3 cpu efficiency tips?
Hello! I am working on a cubasis project on an xsmax and I am experiencing issues with the dsp usage spiking to 100 and the audio crackling
I have been monitoring the cpu throttling using the app Cpu-X and I can see that as the phone gets hotter, the cpu gets throttled down to less than half its speed at the moments that cause cubasis to crackle
I am hoping to find a solution to make cubasis less taxing on the cpu so that it does not heat up and throttle so quickly- is there anyway to increase the latency beyond 11.6 ms? I believe this corresponds to a 512 buffer size- is there any way to make Cubasis run with a 1024 buffer size or higher?
Also- I see this setting in settings under Audio that says:
'Studio Quality'- minimizes the amount of system-supplied signal processing
-I've tried switching this on and off but am still confused what it does exactly and whether it has any effect on the cpu/dsp load... does anyone here understand exactly what this setting does?
If anyone has ANY other cpu optimization tips for cubasis I'd be grateful to hear them
Thank you so much!

Freezing tracks with AUv3 instruments would be my first try.
Stick it in a portable fridge
one interesting discovery- when I switch the phone into airplane mode- the issue disappears completely and the cpu remains very stable
I am going to create a new thread about this- but if anyone has any tips on drastically reducing ios background network activity to bare essentials (incoming texts + calls) I would be extremely grateful to hear them!

That's an interesting find.
Tried this now on my iPhone 8 Plus.. switching to airplane mode had no noticeable effect on the levels of DSP.
@NoiseHorse @cyberheater @rs2000 - interesting discovery 2, if I switch off background app refresh- I can still receive calls + texts etc but don't seem to get the cpu spikes!! wonder which combination of my hundreds of apps is putting a load on the cpu with network activity.... but either way... so far just switching off background app refresh seems to work great, will keep everyone posted on if it continues to do the trick🤞
@LFS ~ thought you might find this bit about background app refresh interesting as well
also-for those looking to maximize cpu/dsp, this is caveman dumb BUT works quite well to combat cpu throttling- a few months ago I started using a lighter and scissors to cut enormous holes in the back of my iphone cases to give the phone room to breath- comparing cpu throttling in CPU-X before and after turning the case into a convertible... the results are extremely noticeable.... I basically just start with a case that has some sort of semi-rigid material on the back plate (pure silicon is too flexible and does not have enough integrity to grip the phone if you cut it's belly out) and then hold a lighter in the middle of the case until there is a bubble, I stick a pair of scissors through that and cut out the back of the case until it's almost just a frame to protect the phone if it is dropped- pic attached below for reference
How did you monitor audio? Headphones? Bluetooth? Audio interface?
@annahahn here’s a thread that is still relevant:
https://forum.audiob.us/discussion/21984/ios11-battery-and-other-survival-tips/p1
It did not have an effect on general dsp level for me , just keep kept it from spiking to 100%
Headphones connected to a dragonfly cobalt interface
first time hearing of this device; worth every penny? --- Also bump for anyone who can offer a practical explanation of the: "'Studio Quality'- minimizes the amount of system-supplied signal processing" button
I've never felt the need to get anything better than the native iDevice headphones output.
Many low-cost audio interfaces sound worse.
It turns off iOS “enhancement” of onboard microphone and speaker audio. It only affects these, not any other audio processing. I believe these enhancements involve some EQ and compression or gain.
