Depending on your Pro Tools system, the
Delay Compensation Engine setting in the Playback Engine determines how much DSP or host-based processing resources are dedicated to Pro Tools Delay Compensation, which manages DSP and host-based delays in the Pro Tools mixer.
Within a session, you can enable or disable Delay Compensation (
Options > Delay Compensation). When Delay Compensation is disabled, it uses no DSP or host-processing resources.
Depending on your Pro Tools system, there are up to four settings available in the Playback Engine to dedicate processing resources for Delay Compensation:
Provides 1,023 samples at 44.1/48 kHz, 2,047 samples at 88.2/96 kHz, or 4,094 samples at 176.4/192 kHz of Delay Compensation for each channel. This is the most efficient setting. For sessions with only a few plug-ins that do not induce too much DSP and host–based delay, this setting should be sufficient.
Allocates 4,095 samples at 44.1/48 kHz, 8,191 samples at 88.2/96 kHz, or 16,382 samples at 176.4/192 kHz of Delay Compensation for each mixer channel. For sessions with a lot of plug-ins resulting in a large amount of DSP and host–based delay, select this setting.
Allocates 16,383 samples at 44.1/48 kHz, 32,767 samples at 88.2/96 kHz, or 65,534 samples at 176.4/192 kHz of Delay Compensation for each mixer channel. For sessions with plug-ins on mixer channels that result in more the 4,000 samples of delay at 48 kHz, select this setting.
