Displays a rough estimate of how much of your computer's CPU is being allocated for processing audio in MSP. Sets a limit (expressed in terms of a percentage of your computer's CPU) Sets a limit (expressed in terms of a percentage of your computer's CPU) to how much signal processing MSP is allowed to do. MSP will not go above the set CPU limit for a sustained period, allowing your computer to perform other tasks without MSP locking them out. The trade-off, however, is that you'll hear clicks in the audio output when the CPU goes over the specified limit. Setting this value to either ‘0’ or ‘100’ will disable CPU limiting.

Vector Optimization (Macintosh only) Toggles whether to select vector optimization in MSP when computing audio on processors that support it. Vector optimization allows four samples to be processed within the space of a single instruction. However, not all audio signal processing algorithms can be optimized in this way (e.g., recursive filter algorithms). Leaving this option on when using MSP will enhance CPU utilization and performance, although the exact performance gain depends on the algorithm you are using and the number of MSP objects that implement it that have been vector optimized.

The pop-up menu is used to set the audio sampling rate. For full-range audio, the recommended sampling rate is 44.1 kHz. Using a lower rate will reduce the number of samples that MSP has to calculate, thus lightening your computer’s burden, but it will also reduce the frequency range.
