What can you tell me about "adding X milliseconds of audio buffering"

[Sebatis]

I'm troubleshooting through various things as a new OBS user. This is for Recording and not streaming.

The current issue is: "adding 21 milliseconds of audio buffering, total audio buffering is now 21 milliseconds (source: Desktop Audio)".

The video and audio seem to be in sync but I may not be the most sensitive to a minor disparity like 21ms. I've done a bit of searching but nothing I've seen seems to apply to my setup.

Correct me if I'm wrong, but the log is telling me that OBS is adding a small delay of 21 milliseconds to my audio before it's processed? Why would it do that? What would trigger the program to behave that way?

Here's the Log File:

The log is incomplete but it's your rig and/or settings causing it. Although 21ms isn't really anything to worry about. FWIW, I used to get the standard 21ms too but after the last audio driver update from my mobo's support page, the buffering completely ceased. (Asus/Realtek driver with Sonic Studio 3 disabled.)

Some settings to change/troubleshoot:
Disable Game DVR & HAGS

11:01:54.815: [WASAPISource::TryInitialize]:[Microphone (Realtek USB Audio)] Failed to initialize audio client: 80070005
11:01:54.815: WASAPI: Device 'default' failed to start (source: Mic/Aux)

Fix your Scene, there should only be (1) Display, Game or Window capture per.

Thanks for the insight!
