PART 3: The Acadia Audio SystemEach of the four sections in the AudioInstruments & Routings Window can beclosed or opened by clicking the appropriateopen/close triangle, see Figure 6.2.SETTING THE NUMBER OFAUDIO INSTRUMENTSNOTE: This section applies to all Visionand Studio Vision users but is most applicableto TDM and Acadia users.Vision can use as many Audio Instrumentsas your memory and CPUresources allow, up to a maximum of 128.Vision initially defaults to 16 Audio Instruments,but you can request a greaternumber if you like. Vision stores therequested number of Audio Instrumentsin both its Setup file and in each Visionfile.Figure 6.2: Busses section, opened and closedVision offers a great amount of flexibilityin routing and processing audio. Whilethe following sections in this chapterexplain the various controls in the AudioInstruments & Routings Window,Chapter 7: Acadia: Audio Channels inConsoles explains how to assign plug-ins,sends, and EQs. In addition,Chapter 10: Acadia: Bussing, Routing, &Bouncing to Disk explores some realworldexamples for bussing, routing, andrecording audio channels.When using the Acadia audio system, thenumber of Audio Instruments you specifydetermines the number of possible audioevents that can sound at any one time,and the amount of RAM used for audiobuffers.IMPORTANT: The number of AudioInstruments you specify determines only thetheoretical number of possible audio eventsthat can play back simultaneously.There are many other factors that affect theactual number of simultaneous audiotracks you can expect Vision to play. Theseinclude: the speed of your CPU; the speed ofyour hard disk (and the speed of its IDE/SCSI connection); the number of EQ bandsin use; and the number and type of VSTplug-ins employed.
