Delay Compensation
Compensation
Overview
When UAD Powered Plug-Ins are used, audio data to be processed by a Pow-
ered Plug-In is sent by the host application to the UAD card. The audio is then
processed by the UAD card and sent back to the host application.
This back-and-forth shuffling of audio data produces a latency (delay) in the
audio signal being processed. Latency time is determined by the sample rate,
the hardware device driver (ASIO or similar) buffer setting, and the Extra Buff-
ers (if any) in the UAD Configuration window.
If this latency is not compensated, the processed audio will not be perfectly
synchronized with unprocessed audio. Fortunately, most host applications au-
tomatically compensate for this latency when plugins are used on track inserts
by simply turning on the “Plugin Delay Compensation” or similar Preferences
setting. Some hosts even provide “Full Plugin Delay Compensation” through-
out the entire signal path, including sends, groups, and buses.
Important: Delay compensation is fully automatic and requires no user in-
tervention when UAD Powered Plug-Ins are used in hosts that support “Full Plu-
gin Delay Compensation.”
