I wanted to know if I can use Audacity to filter background noise during a video call. Is it possible?
Thank you in advance.

Audacity is a post production editor. It doesn't do anything in real time except its event timer.

Re: Filter background noise during a video call?
What sort of background noise are you talking about? Most communication systems already heavily process their voices to work at all. If you pile a third party noise reduction system on top of that, I'm guessing you're going to produce hollow, wine-glass, milk-jug trash.
This is also why it is recommended that multi-point podcasts talk to each other on-line for timing, but record each local microphone in super high quality with little or no processing. Shuffle sound files later.
That isn't remotely real-time, but the quality can be enormously better than recording the conference.
Noise Reduction systems tend to not work with "noise" that moves. Nobody can take out a cat, dog, or TV set in the background of a recording, other than possibly second-by-second manual editing.
Do you have control of the far end? There are some fancy-pants microphones that do pretty well.
