24.1. MANAGING THE CPU LOAD 343

speed include the processor's clock rate (e.g., speed in MHz or GHz), architecture, memory

cache performance (how efciently the processor can grab data from memory) and system

bus bandwidth  the computer's pipeline through which all data must pass. For this

reason, many people involved with pro audio use computers that are optimized for musical

applications.

The CPU Load Meter.

The Control Bar's CPU meter displays how much of the processor's computational potential is

currently being used. For example, if the displayed percentage is 10 percent, the computer

is just loang along. If the percentage is 100 percent, the processor is being maxed out  it's

likely that you will hear gaps, clicks or other audio problems. Note that the CPU meter takes

into account only the load from processing audio, not other tasks the computer performs

(e.g., managing Live's user interface). Audio calculations have the highest priority in Live.

Therefore, even if the CPU shows a high percentage of processor usage, the audio stream

should remain uninterrupted. However, non-critical functions (such as screen redraws) might

slow down because these tasks are handled only when the audio processing lightens up

a bit.

24.1.1 CPU Load from Multichannel Audio

One source of constant CPU drain is the process of moving data to and from the audio

hardware. This drain can be minimized by disabling any inputs and outputs that are not

required in a project. There are two buttons in the Audio Preferences to access the Input

and Output Conguration dialogs, which allow activating or deactivating individual ins and

outs.

Live does not automatically disable unused channels, because the audio hardware drivers

usually produce an audible hiccup when there is a request for an audio conguration
