When Nvidia introduced the free Nvidia -Broadcast -App in 2020, she promised to use the RTX GPUS AI functions to increase the video and sound quality of the user recordings, provided they had the right hardware. This can be useful if the integrated webcam and microphones of a laptop may not capture the best -looking footage or the richest audio and streamers could possibly help to get to get by with a cheaper setup. With version 2.0 of the Nvidia -Broadcast -app that was published on Heck at the end of JanuaryThe skills are increased even higher … maybe a little too close to the sun.
In Nvidia Broadcast 2.0, microphones still have options for removing noises and removal of room -Cho, but now there is also a studio -voice effect in the beta, which “improves the quality of your microphone, to a high -end studio To simulate “. For a video, the app can still make changes to its background (replace, blur or essentially green screening), remove the noise from granular film material, zoom and keep it automatically and strangely what your eyes look, how your eyes look in The camera. However, virtual lighting is new with the update to better highlight it in your video.
Some of these new functions require powerful GPUs. Studio voice, video noise removal and virtual key light demand a “high-end GPU” and are not recommended for use when playing or in other GPU intensive applications. All functions require RTX hardware, i.e. you need at least one RTX 2060 or higher to try them out. However, they require for the functions that require a “high-end GPU”. Nvidia says An RTX 4080, 5080 or higher is “required”. Nevertheless, I was able to perform both functions on an RTX 4060 Mobile GPU.
Nvidia broadcast in action
The idea behind these AI functions is cool, but how well they actually work is still in question. On the one hand, they may be as demanding as Nvidia says. By executing the virtual light or studio language function on my RTX 4060 laptop it was shown that the GPU was absolutely added by the process. The integrated GPU utilization monitor from NVIDIA showed red, whereby the RTX 4060 draws 60 watts to maximum and the power overlay. The fans of my laptop even rose as if I were playing with full throttle. From an economic point of view, however, these functions are expensive, no matter how they look at them. You must have powerful hardware to carry them out and then do this hardware hard. Plan these functions on a desktop computer or connected with your laptop.
Then there is the more important matter how they really look and sound. Let’s start with video.

The eye contact tool, although it was available before the broadcast 2.0, has now come out of the beta. But I am not convinced that it should be. Sure, it looks like I’m staring into the camera in video material. But in my tests, I had large blue eyes without exception that made me look like a white hiker game of Thrones. I don’t have blue eyes as a reference. Even when I took an eye contact with the camera, the Nvidia show still insisted on editing my eyes and making it blue.

The virtual key light did what it said. It created artificial lighting to strengthen the brightness on me without increasing the brightness throughout the video. However, the results did not impress me. I just look like I have become radioactive. The lighting is very unnatural.
As far as the audio is concerned, it blushes quite impressive at first. The microphones on my laptop are not very good. They even put audio in a quiet room that sounds far away and slightly steamed. With an activated studio voice, my voice ends much fuller and clearer. But listening exactly, there is a strange digitization. It is difficult to characterize, but it doesn’t sound as if it really was my voice. It sounds more like a recording of my voice in a language clone, and then it repeated everything I said. Everything is just a little stilted and trembling. Listen below:
The Studio Voice function cannot save the microphone in a poor recording environment. Testing in a small room with a box fan that runs with full explosion, the audio was a dramatic improvement in clarity compared to the raw recordings from the microphones, but it was still audibly processed, and the efforts to subject the background noise Particularly strange.
If you have a half decent microphone, the studio voice could make it even worse. I did additional test recordings with the built-in boom microphone on the Audeze Maxwell headset so that it was wired directly into my laptop. Both in a calm and loud space, it delivered a loud, clear and complete recording of my voice without a studio being activated. In both cases, switching on Studio Voice then introduced a difficult to abuse digitization that not only made the audio worse, but also made it more difficult to understand.
Can Nvidia Ai replace proper streaming setup?
In view of the hardware requirements, the performance requirements and the quality of the results, the stars really have to adapt to these newer Nvidia round functions in order to really feel worthwhile. If you definitely have an Nvidia system, play with the tool. Some of the functions can be useful, like automatic framing. But I would not recommend going out for a new NVIDIA GPU just so that you can save money for audio and video recordings, especially if you want to approach the professional quality. And do not forget that the performance of the GPU, which tries to carry out these functions, will add up over time.
The audio quality that I received from Studio Voice – maybe limited by the RTX 4060 in my system – was not regularly faded with some kind of audience and compared to the quality I could only get from a headset with a boom – Microphone. I tested a lot From gaming headsets and even very cheap cable heads with a boom microphone are better than what I heard from Studio Voice.
The eye contact function was nothing more than worrying, and I don’t think it makes someone believe that they actually make eye contact with them. And the virtual key light, like the studio voice, does not seem to be a high quality replacement for a real key light, especially if affordable LED lights are a dozen.
