How to Decrease CPU Usage
If you experience unusually high CPU usage, you can try changing the EQ module to Analog mode.
You can also try increasing your host application’s buer size to decrease CPU usage. We understand
that these solutions might not be adequate for many users, so we’ve also designed Ozone to be
optimized for any host application setup.
If you are using Ozone at low latencies and rely heavily on these DSP modules, you will want to adjust
the buer sizes to get Ozone’s CPU consumption as low as possible. At first it may seem unintuitive,
but if you follow the tips here then you should be able to tweak your buers very quickly and easily.
Optimizing Ozone
To get the best buer settings for your setup, first you should have an idea of what kinds of buers
your host application is sending. You can use Ozone’s Buer Size Viewer to do this, in the plug-in
version of Ozone (but not the standalone version).
To do so in the plug-in version, navigate to Settings -> General -> Host -> View Buers.
Once you know what size buers your host application is sending, try the following:
• Place Ozone’s Equalizer in digital mode, and bypass all modules except for the Equalizer. Set
the EQ filter size to the size you most commonly use.
• Set the EQ buer size to the number that’s closest to your host application buer size.
• Open a CPU meter. Many host applications have a CPU meter built in, but if you’re running
Windows you can also press Ctrl+Shift+ESC and select the Performance tab. Note that CPU
meters are usually somewhat inaccurate, but we’re just looking for relative changes in CPU
usage.
• Open an audio file with typical settings (sampling rate, bit depth, number of channels) for your
use and play it through Ozone. If you usually use Ozone in a multitrack environment then be
sure to do the same here. As the audio plays, try adjusting the EQ buer size, and see what
eect it has on CPU consumption. Buer sizes near the host application buer size are a
good starting point, but the best choice depends on many aspects of your system and host
application, which are beyond Ozone’s control.
Ozone’s CPU consumption for this setup should now be optimized. If you change the way you use
Ozone, for example if you move from 44.1 kHz to 96 kHz, or you move from a single-track setup to a
multitrack setup, then you may want to repeat these steps to make sure your buer settings are still
optimal.
We’ve gone to great lengths to optimize Ozone’s internal DSP without compromising sound quality.
We hope these steps help make Ozone useful in a wide variety of setups. These steps should help you
address those variables which are beyond our control and quite often very dierent for dierent users.
