Notes
- All measurements are taken at a sample rate of 44.1 kHz.
- DSP % indicates the amount of resources required by one UAD plug-in instance on a single SHARC processor. This measurement is from the System panel in the UAD Meter & Control Panel application (not the blue UAD Meter gauge, which shows averaged DSP loads of all available SHARC processors).
- DSP savings and higher instance counts can be achieved with plug-ins marked with an asterisk ( * ) by disabling UAD-2 LoadLock (in the UAD Meter & Control Panel application) and turning off sections of the processor. See the UAD Plug-Ins Manual for details.
- Apollo uses UAD DSP and memory for its internal DSP mixer, therefore the UAD Meters will show some DSP and memory usage when Apollo is connected even if UAD plug-ins are not loaded, and instance counts in the chart are higher than available on Apollo-only systems.
- The UAD system can process a maximum of 512 simultaneous UAD plug-in instances. High UAD plug-in counts (in the hundreds) may be constrained by overall system performance which is affected by host CPU loads, hardware I/O buffer settings, available bandwidth, the particular DAW in use, and related performance factors.
- As of v6.2.0, UAD-2 FireWire devices (Satellite and Apollo*) have a maximum limit of 58 stereo or 116 mono plug-in instances, and counts for these devices are subject to these limits. These theoretical limits are based on a 44.1 kHz sample rate with a FireWire 800 connection and the UAD Bandwidth Allocation set to 85% in the UAD Meter & Control Panel. For FireWire bandwidth tuning information, see "Optimizing Performance" on the Apollo support page. *Note: This limitation does not apply to Apollo when it is connected via the Thunderbolt Option Card.
- UAD plug-in PGM usage is not listed in the chart because unlike DSP usage, the “per plug-in” PGM value doesn’t simply sum when multiple UAD plug-ins are used, and the interdependencies of this resource are not linear.
