Chapter 1 Flashcards
What are some of the differences between standard Protools software and Protools HD Software ?
Software:
- Total voiced tracks (128 mono/stereo)
- Total allowed tracks(128)
- Video Tracks (1)
- I/O (32)
Without HD Hardware:
- Total voiced tracks 256
- Total allowed tracks 764
- Video Tracks (32)
- I/O(32)
Native hardware HD
- 64 I/O
What are the five main (required) componenets of any Pro tools HD-series hardware system?
- Computer
- Protools software
- Hard drives
- PCIe cards/Thunderbolt
- Audio Interface
What are some optional components?
- HDX Card
- Additional audio interfaces
- PRE
- SYNC HD
HD OMNI
- 4 channel analog inputs
- 8 channel analog outputs
- 24 bit converters
- sample rates up to 192 kHz
HD I/O
- 8x8x8 (8 analog in, 8 analog out and 8 digital in and out)
- 24 bit converters
- 192Khz Sample rates
HD MADI
- 64 channel digital audio interface that supports the Multichannel Audio Digital Interface
- up to 192 Khz sample rates
Advantage of using Protools HD native hardware over a system without HD series hardware
- incorporate 64 channels of I/O
- Hardware based power
- enhanced low-latency control
- Uses FPGA to handle real time routing and low latency monitoring
What does FPGA stand for?
-Field programmable gate array
What are some of the benefits of floating-point processing?
- mantissa provides 300 dB of dynamic range
- 64-bit point sees Pro tools retain full 52 bits of precision

What does the Current Engine setting in the Playback Engine dialog box determine ?
-Determine which audio engine will be used with the connected audio interface
What impact does the H/W Buffer size setting have on performance in Protools 11?
- Affects plug-in performance
- thru-monitor latency
Under what conditions are plug-ins affected by the H/W Buffer size
low latency domain
What does Disk Playback Cache Size determine ?
Determines the amount of (RAM) used by the Avid Audio Engine to manage disk buffers.
When is it useful to increase the Cache Size setting?
When you are working with shared media storage
What window allows you to monitor the allocation of processing power and system resources in your session
System usage window
What adjustments might you make on a Protools HD Native system based on the meter graph displays in this window.
- Lower the Disk Cache setting
- Disable video engine
- Install more RAM
