Study Notes

Playback Engine Dialog Box

The Playback Engine dialog box determines a system's performance and can be adjusted to accommodate various workflows.
It allows changing the playback device to fit specific needs.
The process of changing devices is similar to choosing an initial device: select the desired device in the Playback Engine pop-up menu.
Changing devices affects input and output (I/O) configuration, managed in the I/O Setup dialog box.

Hardware Buffer Size

A buffer is an allocated amount of computer memory for temporary data storage to ensure stable performance.
Pro Tools has two hardware buffers: Low Latency and High Latency.
The Low Latency Hardware Buffer applies to tracks with live inputs (e.g., record-armed audio tracks).
The High Latency Hardware Buffer applies to tracks without live inputs (e.g., playing back audio).

Choosing the Best Hardware Buffer Setting

There is no single best setting for the Hardware Buffer.
A low buffer setting provides low recording latency, but factors like plug-in effects, recording tracks, and virtual instruments may require higher buffer settings.

Video Engine

The Video Engine enables or disables the Avid Video Engine (AVE).
Enable it only when needed, as it consumes system memory.

Ignore Errors During Playback/Record

This setting suppresses errors related to processing, but may compromise audio quality.
Enable it only when necessary, and disable it when recording or creating a final mix.

Minimize Additional I/O Latency

Available when Ignore Errors During Playback/Record is enabled.
Limits the amount of latency needed to its minimum value (128 samples).

Dynamic Plug-in Processing

Introduced in Pro Tools version 11, it only draws CPU power for plug-ins when there is audio to be processed.
Enable this feature for a boost in processing power.

Optimize Performance at Low Buffer Sizes

Improves CPU performance at small Hardware Buffer settings.
Enable it, except in cases where certain plug-in effects cause system hangs.

Limit Number of Real-Time Threads

Applies only to Intel-based Mac computer systems.
Enable it to resolve conflicts with other applications using real-time threads.
Disable it when recording if possible.

Intel Turbo Boost

Available on Intel-based Mac systems with Turbo Boost support.
Enables the CPU to accelerate beyond its rated frequency, but may cause fan noise.
Enable it, but disable if fan noise becomes a problem.

Disk Playback

Copies audio from storage into RAM for playback, optimizing system performance.
Allows multiple interfaces to be used simultaneously.

Hardware Setup Dialog Box

Configures and monitors system performance.
Options vary based on attached hardware.
Accesses device settings and proprietary software.

Using a Computer's Built-In I/O

Convenient for producing on the go with a laptop computer.
Process differs between Mac and Windows-based computers.
