Why would anyone build with this?

REASON 1

Enable live denoising on your microphone so video calls sound clear despite a noisy room.

REASON 2

Clean up a podcast or video recording after the fact using the pre-trained model.

REASON 3

Route the denoiser's live output into your OS's audio system so any call app picks up the cleaned mic.

REASON 4

Train a custom denoising model on your own noisy dataset using the included training code.

Yoink these prompts

Prompt 1
Show me how to install facebookresearch/denoiser and run its pre-trained model to clean up a noisy .wav recording.
Prompt 2
Walk me through setting up denoiser for live, real-time microphone denoising during video calls on my laptop.
Prompt 3
Help me route denoiser's real-time output as a virtual microphone input on macOS so Zoom picks up the cleaned audio.
Prompt 4
Using denoiser's training code, explain what a custom dataset needs to look like if I want to train a model for a specific type of background noise like traffic.
