    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.
