Summary
Working from home for me means panicking moments before meetings and telling everyone in the house to be mindful of background noise while I’m on the call. I’ve lost count of how many times I’ve had to apologize for my poor mic quality on these calls, which sounded unprofessional because of the ambient noise — especially the loud fan noise in my room, which I can’t really turn off in peak summer. I thought I needed a new pair of headphones to avoid embarrassing myself again until I downloaded Nvidia Broadcast, which improved my cheap mic’s audio to near-studio quality. How Nvidia Broadcast helps fix your mic problems AI noise suppression that works locally instead of the cloud The AI features in Nvidia’s newer GPUs go far beyond just generating fake frames and resolution upscaling. Thanks to the AI features in RTX cards, these GPUs can also single out your voice and suppress background noise to give you a studio effect with your cheap mic. Nvidia Broadcast doesn’t just mute frequencies beyond a specific decibel point; it recognizes your voice and ignores other frequencies, whether loud or quiet. Nvidia has extensively trained the AI model in Nvidia Broadcast to identify and distinguish human speech characteristics and suppress unwanted sounds like keyboard clicks and fan hums. Nvidia’s Tensor Cores handle all the processing required to run these AI effects locally rather than in the cloud. Your webcam gets an upgrade as well A cheap webcam suddenly looking a lot more expensive Not all calls are audio-only, and a cheap webcam can ruin your reputation, especially when it doesn’t match the quality of the other people on the call. Fortunately, Nvidia Broadcast works for video as well, and it is loaded with tons of AI features, including:
- Virtual Background: Removes the original background without a green screen and replaces it with one of your choice. Even if you don’t want a background, it can just blur the image.
- Virtual Key Light: This effect simulates having a light on your face in dim environments, making you appear more visible.
- Video Noise Removal: In low-light environments, cheap, older webcams can produce grainy, noisy images that look like CCTV footage, and you don’t want to give off that impression in a professional work environment. Nvidia Broadcast can help reduce noise and grain in these situations, giving you a clearer image.
- Eye Contact: Even if you’re looking away, the app’s AI model makes it seem like you’re focused on the camera.
- Vignette: Darkens the corners of the frame to draw more attention to the subject.
- Auto Frame: Depending on how you move around the camera, Auto Frame crops or zooms in to keep you centered. How to set up Nvidia Broadcast Doing so takes just minutes of your time You can download Nvidia Broadcast from the official Nvidia page, but you’ll need at least an RTX 2060 GPU and 8GB of RAM to run the app. Since Nvidia Broadcast needs several AI models, the additional download can take up a hefty amount of space, around 1.5GB. To set up noise suppression, select your microphone at the top of the microphone options and then enable noise suppression and room echo removal if your room has that problem. You can test your microphone to see the results. To use the webcam features, go to the camera tab and select your camera. From there, you can select the features you want to enable and then test how you appear. To use the AI features in Nvidia Broadcast, you have to use “Broadcast” labeled devices since the AI features won’t work on the original devices. No Nvidia GPUs? There are other options AMD users have their own options, and Windows has a similar dedicated app for NPU systems If you don’t have an Nvidia GPU, alternatives work similarly to Nvidia Broadcast. For AMD users, the noise suppression feature works similarly to Nvidia’s counterpart; you can enable it in AMD Adrenalin Edition by going to Settings → Audio & Video. Do keep in mind that you’ll need either a Ryzen 6000 CPU or later or an RX 6000 or newer GPU. Other than that, Windows Studio Effects offers similar AI features like noise suppression, portrait lighting, background blur, voice filters, and other filters that can help you enhance your webcam and microphone in online meetings; however, they require an NPU-based system, which is quite rare and found only on newer laptops. To download them, go to your manufacturer’s website (e.g., MSI or HP), go to the driver page, and find the Windows Studio Effects drivers. Then, you can enable the aforementioned features by selecting your devices in the Settings menu, where you’ll find options for supported features like background effects, background noise suppression, etc. You’re not buying new gear, just getting software-based enhancements Nvidia Broadcast provides software-based enhancements, and it doesn’t magically improve your audio quality — it just helps human speech stand out by filtering ambient noise. Similarly, the app won’t replace a better camera, but it can help make the picture look noticeably better on the existing one. Other alternatives work similarly, but AMD doesn’t offer webcam features, so you’ll need to download Windows Studio Effects for that. However, with AMD, you have the advantage that noise suppression is built directly into the default Adrenalin software, so you won’t need to download anything else.
