The following table lists what is processed by your computer’s native CPU versus UAD DSP when using LUNA.
| Processed by native CPU | Processed by UAD DSP |
LUNA Recording System app LUNA API Vision Console Emulation (A.R.M. inactive) LUNA Extensions Audio Units plug-ins/instruments VST3 plug-ins/instruments | UAD DSP Plug-Ins LUNA API Vision Console Emulation (A.R.M. active) A.R.M. Channels in LUNA |
In LUNA, the Host and UAD-2 buttons in the System Info area can be clicked to display Audio Settings such as the sample rate, native CPU (Render/Render IO/Memory), and when Apollo, Satellite or UAD-2 hardware is connected, UAD (DSP/Program/Memory) resource loads used by LUNA.
When using a Volt or other third-party interface, the native CPU information will show:
- Render Meter - The amount of computer CPU used by all native processing.
- RenderIO Meter - The amount of computer CPU used by plug-ins on Instrument tracks in ARM mode.
- Memory - The amount of computer memory used by LUNA.
When using Apollo, Satellite or UAD-2 hardware, the UAD-2 hardware resources will also show:
- DSP - The averaged amount of digital signal processing resources that are being used by the UAD plug-in algorithms.
- PGM - shows how much UAD program memory is in use by UAD plug-ins.
- MEM - indicates the percentage of UAD random access memory that is currently in use by UAD plug-ins.
Note: Only Apollo’s internal UAD DSP can be used for ARM input processing, even if UAD-2 Satellite and/or UAD-2 PCIe accelerators are connected to the system.
