I just pushed a draft PR that adds noise reduction support to the AudioBridge plugin in the #Janus #webrtc server via #RNNoise. It still doesn't 100% works all the time, due to the fixed number of samples RNNoise expects (and that I'm figuring out how to work around) that has different implications depending on the sampling rate in use in a room, but it's definitely a good first step I think!

#Audio #Tool
#JeanMarcValin: "This #demo presents the #RNNoise project. The main idea is to combine classic #SignalProcessing with #DeepLearning to create a #RealTime #NoiseSuppression #algorithm that's small and fast. No expensive GPUs required — it runs easily on a #RaspberryPi. The result is much simpler (easier to tune) and sounds better than traditional #noise suppression systems."

#PulseAudio

This is #RNNoise the library that the new #OBS 26 uses to clean up audio. Here is a sample of the cleaning ability.

Playing with the #RNNoise noise suppression library in #OBS on #Linux. This was done for my amusement, any useful information presented is purely accidental.
