We are currently using it for the “your microphone is noisy” notification feature, not for actual noise detection.

With Audio Worklets or insertable streams, however, it should be possible to apply it to the stream im real time, though we haven’t tried it yet.

The repository is under the Jitsi organization, so I'd say chances of them using it or at least planning to use it are quite high.

You can try in Mumble.
