Nvidia RTX Voice is an application used to enhance voice audio quality by reducing background noise using an AI algorithm. Back when Nvidia
introduced the technology, the company stated that it used Tensor cores to run the app, but soon after its release, users found a way to use it on non-RTX cards without Tensor cores. System requirements also included Windows 10 as the minimum, but Windows 7 was also supported using the workaround.
However, you will still need an RTX GPU to take advantage of Nvidia Broadcast, which contains a newer version of RTX Voice as well as other features, such as virtual green screen. You can still download RTX Voice as a standalone application though. Those interested can download RTX Voice,
