How to Install Noise-Cancelling: Step-by-Step

Quick Answer

Noise-cancelling software reduces background noise from your microphone or speakers using digital signal processing. Installing it takes just a few minutes and works with most Windows and Mac systems without extra hardware.

Whether you''re gaming with your squad, attending online lectures, or hopping on a work call from a busy household, background noise kills the experience. Noise-cancelling software is the fastest, most affordable fix - no new microphone required. Here''s exactly how to get it running.

What Is Noise-Cancelling Software and How Does It Work?

Noise-cancelling software uses AI-driven digital signal processing (DSP) to identify and suppress unwanted ambient sounds - fan hum, keyboard clatter, traffic, or voices in the background. It sits between your microphone input and your communication app, acting as a real-time audio filter. Unlike hardware active noise cancellation found in headsets, software solutions run entirely on your CPU or GPU and can be applied to any existing microphone. Popular free and paid options include NVIDIA RTX Voice (requires an RTX GPU), Krisp, and Windows 11''s native noise suppression built into settings.

Step-by-Step: Installing Noise-Cancelling Software on Windows

Start by identifying your GPU - NVIDIA RTX card owners get the best results with RTX Voice or Broadcast, which offloads processing to the Tensor Cores and produces near-studio quality. Download the installer from NVIDIA''s site, run it, then open the app and select your microphone as the input device. Enable the noise removal toggle. Next, open your communication app (Discord, Teams, Zoom) and under audio settings, set the input device to the virtual microphone created by the software - usually labelled something like ''NVIDIA RTX Voice.'' If you''re on an AMD or Intel system, Krisp offers a free tier that works similarly: install, select Krisp Microphone as your input in your app, and you''re live. Windows 11 users can also navigate to Settings → System → Sound → your microphone → and toggle ''Noise suppression'' under advanced settings for a lightweight built-in option.

Configuring and Testing Your Setup

After installation, always test before a real call or session. Open your app''s audio test feature and speak normally while simulating background noise - clap near a fan, play music softly. Listen to the playback. If noise bleeds through, increase the suppression intensity level in the software''s slider. If your voice sounds hollow or robotic, dial suppression back slightly - over-aggressive filtering removes voice frequencies too. Most software lets you create profiles for different environments. Set up a ''home'' profile and a ''loud environment'' profile and switch as needed. CPU usage is worth monitoring: Krisp on a mid-range CPU can consume 3–8% - acceptable, but close background apps if you notice frame drops during gaming.

Frequently Asked Questions

Q: Do I need an expensive microphone for noise-cancelling software to work? A: No. Software-based noise cancellation works with any microphone including built-in laptop mics and basic headset mics. A better source microphone does improve the baseline quality, but the software will still effectively suppress background noise regardless.

Q: Will noise-cancelling software affect my gaming performance? A: Minimally. NVIDIA RTX Voice offloads to Tensor Cores and has near-zero gaming impact. CPU-based solutions like Krisp use a small percentage of CPU cycles - on modern processors this is negligible, but monitor your usage if you''re on an older quad-core system.

Q: Can I use noise-cancelling software for my speakers or headphones, not just my mic? A: Yes. Most applications let you apply noise suppression to your output (speaker/headphone) stream as well, filtering incoming audio from other callers. This is separate from microphone suppression and requires selecting the virtual output device in your app.
