UAD Delay Compensation
Latency & Delay Compensation
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 device. The audio is
then processed by the UAD device and sent back to the host application. This
back-and-forth shuffling of audio data is called “buffering” and it produces a
latency (delay) in the audio signal being processed.
Latency is inherent in digital audio systems and it can be detected in certain
situations. Latency time in a DAW is usually determined by the sample rate
and audio I/O interface hardware buffer size settings.
If this latency is not compensated, the processed audio will not be perfectly
aligned (synchronized) with unprocessed audio. Fortunately, modern audio
plug-in host applications automatically compensate for this latency by simply
enabling the delay compensation function in the preference settings. Most
hosts provide full plug-in delay compensation throughout the entire signal
path, including inserts, sends, groups/buses, and outputs
UAD latency and plug-in delay compensation is managed automatically by
all modern DAWs using automatic plug-in delay compensation. Additionally,
latency can be reduced to undetectable levels in the UAD-2 PCIe card by by-
passing host buffering altogether (see
).
Note:
Delay compensation is fully automatic and requires no user interven-
tion when UAD Powered Plug-Ins are used in hosts that support latency delay
compensation.
Host Application
Settings
For optimum results, the delay compensation feature should be enabled in the
host application. This will provide automatic compensation when UAD plug-
ins are used. This option is usually found in the audio or plug-in preference set-
tings window. The specific location of the setting for this option can be found
in the host DAW documentation.
Latency compensation has various names depending on the host. It’s usually
referred to as “Automatic Delay Compensation” (ADC), “Plug-In Delay Com-
pensation” (PDC) or a similar related name.
