What does the mantissa do?
The mantissa increases the amount of dynamic range
What is the difference between saying things at the session level vs the system/root level?
- Session level is only saved with that specific Pro Tools session
- System/Root level saves the information to the computer
How do you access the hardware setup dialog box? What does it do?
Setup > Hardware
The hardware dialog box allows you to configure the physical input and output connections on an audio interface that route signals into and out of Pro Tools
What use does the MAIN tab in the Hardware Set Up Dialog Box provide?
- Shows the input and output routing for the selected audio interface
- You can select input and output connections on the audio interface and route them to the available channel pairs to and from Pro Tools
What options are included under the MAIN tab in the Hardware Setup Dialog Box?
- AES/EBU
- S/PDIF
- Optical (S/PDIF)
- ADAT
- TDIF
- Optical ADAT
- Word Clock
What use does the ANALOG IN tab in the Hardware Set Up Dialog Box provide?
- Configure reference levels & limiter settings for each analog input channel
What use does the DIGITAL tab in the Hardware Set Up Dialog Box provide?
- Set up the input format and sample rate conversion for any digital I/O cards in an HD I/O
How do you access the Playback Engine dialog box? What functions are available in the Playback Engine Settings?
Setup > Playback Engine
- Allows you to select the audio engine
What does the Hardware Buffer size do? What kind of plug-ins does the Hardware Buffer Size effect?
- It sets the number of samples processed at once during a processor cycle
- Native Plug-ins ONLY
Will plug-ins on AUX input tracks that are receiving live input be processed on the high-latency domain or the low-latency domain?
They will be processed in the low-latency domain.
Will the virtual instrument plug-ins be processed on the high-latency domain or the low-latency domain?
They will be processed in the low-latency domain.
Will plug-ins on audio tracks that are in record or input monitoring mode be processed on the high-latency domain or the low-latency domain?
They will be processed in the low-latency domain.
How will all other plug-ins be processed in the absence of side-chaining?
They will be processed in the high-latency domain
What is the fixed buffer size for the high-latency domain?
- 1024 samples for 44.1 and 48 kHz
- 2048 samples for 88.2 and 96 kHz

Hardware Buffer Size Settings
What does the Disk Cache determine?
The amount of memory (RAM) used by the Avid Audio Engine (AAE) to manage disk buffers
What does the NORMAL disk cache setting do?
It estimates how much cache is needed
How should you set your cache?
