Nvidia RTX Voice: How To Enable AI Noise Reduction For Discord, OBS & Co.


With Nvidia RTX Voice, the graphics specialist now also offers AI-based noise cancellation for the input and output of any audio hardware. The software delivers amazingly good results.

Many voice and video programs can suppress noise, even ex works, for example Discord with the Krisp function. The special thing about

                        
                                                                                                                                        Nvidia RTX Voice
                                            : The software can use the specialized tensor AI units of the RTX graphics processors of the same name for intelligent and self-learning noise suppression.

RTX Voice not only improves the outgoing voice quality via the microphone, but can also free incoming calls from annoying background noise. This works amazingly well, as initial tests show: Even irregular typing noises, such as from loud mechanical keyboards, filter out RTX Voice unerringly.

To start with, the beta version of Nvidia RTX Voice supports the voice and video programs Battle.net Chat, Discord, Google Chrome, OBS Studio, Skype, Slack, Steam Chat, Streamlabs, Twitch Studio, WebEx, XSplit Broadcaster and Gamecaster as well Zoom. More apps will be added gradually.

Nvidia RTX Voice: Requirements

  • Windows 10 operating system

  • Graphics card with Nvidia Geforce RTX 20×0 graphics processor. Optional: graphics card with Nvidia Geforce GTX 10×0 graphics processor (see box at the end of the article)

  • Graphics card driver Nvidia Geforce 410.18 or higher (

Nvidia RTX Voice: configuration

Start RTX Voice. Select your microphone under “Input device” and activate the option “Remove background noise from my microphone”. If you also want to filter out the background noise from incoming calls, select your headphones or speakers under “Output device”. Right below you have to check the option “Remove background noise from incoming audio”.

You can now generally switch the output and input of sounds for all programs to “RTX Voice”. To do this, right-click on the loudspeaker symbol in the lower right of the task bar and select “Open sound settings”. Under “Output, select output device” set “RTX Voice”. Repeat the whole process under “Input, select input device”.

Alternatively, you can of course set the noise suppression method individually for each program. RTX Voice can also be switched on or off directly in Discord, OBS & Co.:

Discord:

Use the gear wheel in the lower bar to call up “Settings, Language & Video”. Here you can now select “RTX Voice” as input and output devices in the sound settings.

Google Chrome:

Use the three dots at the top right to switch to the settings menu. Select “Page Options, Microphone” there.

OBS Studio:

Via “Settings” you get to the “Audio” menu. Under “Devices” select the options “Mic / Auxiliary Audio” and under “Advanced, Monitoring Device” to activate “Nvidia RTX Voice”.

Skype:

Under “Audio & Video” you can select “RTX Voice” as the microphone and speaker.

Slack:

When you call, click on the gear wheel in the top left corner and activate RTX Voice for loudspeaker and microphone in the “Audio settings”.

Twitch Studio:

In the settings menu you will find the “Audio Options”. Select “Microphone Nvidia RTX Voice” as the primary microphone. Finally, disable Twitch Studio’s proprietary noise cancellation.

WebEx:

If you want to join a meeting, select “Call Using Computer” and “Nvidia RTX Voice”.

XSplit:

Activate the “Nvidia RTX Voice” option in the “System, Sound” audio settings under “Speakers” and “Microphone”.

Zoom:

Call up the audio settings in the options menu and activate “Nvidia RTX Voice” as speaker and microphone.

Unlock RTX Voice for graphics cards with Geforce GTX 10×0

Officially, Nvidia

                        
                                                                                                                                        RTX Voice
                                             only released for graphics cards with RTX graphics processor – presumably to offer further incentives to buy the expensive graphics cards. With a trick, however, owners of Geforce GTX graphics cards of the 10th GPU generation “Pascal” can also enjoy the clever noise suppression software. In this case, however, the Geforce GTX 10×0 graphics card cannot use the specialized tensor computing units, but has to fall back on the conventional Cuda units. This can cost some computing power in voice chat in games.

How to use RTX Voice with GTX 10×0 graphics cards: Start the installation of RTX Voice. If the error message “no RTX GPU found” appears, open the file “RTXvoice.nvw” as administrator in the text editor in the directory “C: temp NVRTXVoice NvAFX”. Delete the section “constrains”:

(

Click “File” and “Save” in the text editor. Close the text editor. Finally, run the RTX Voice installation program again in the higher-level directory “C: temp NVRTXVoice” by double-clicking on “setup.exe”.
