AUDIO DECK

Component Overview

The Audio Deck is a processing sub-system that moves digital audio data between

SCSI storage devices and MADI (Multi-channel Audio Digital Interface) signal ports.

In essence, this R-1 module converts data transmitted and received in bursts

(packets) from storage devices into evenly clocked synchronized streams of digital

audio.

The Audio Deck uses a control processor to know when and what to record or

play. This control system communicates with the Pilot Computer for information

about stored settings, audio event schedules, and user input. The communication

path for such control data is IEEE 1394. This control path is also designed to allow

the Audio Deck to move actual audio data to and from the Pilot Computer, where

the R-1 system can be attached to a network (including machines of various

operating systems) or to other storage devices formatted for the Windows operating

system. R-1 release 1.0 software, however, does not include audio data

transmission features.

The Audio Deck includes a complete Transport Engine. Not only does the deck

convert SCSI to and from MADI, but the deck provides the mechanisms for this

process to be controlled in very much the same way as a conventional tape machine

even while doing things that a conventional tape machine cannot begin to do, such

as Locate instantly to any Cue. Some features of the Transport Engine.

• 4 SHARC DSPs

• Same-track real-time punch and edit crossfades

• 24 tracks of playback or recording from a single drive

• 24 tracks of playback and simultaneous seamlessly monitored punch in/out from

two drives

• 24 tracks of constant Sample Rate varispeed recording and playback

• 24 tracks of Jogging/Scrubbing transport motion

• Clickless start and stop of audio playback

The Audio Deck also includes a router and monitoring mixer. The deck provides

basic routing of it’s input MADI channels to its available 24 channels of recording.

This is in addition to any routing of MADI external to the deck. The deck also

provides a monitor mix of its 24 channels of output.
