What Is A-Volute NS? Nahimic Audio Explained for Windows

A-Volute NS is a DLL component of Nahimic audio software. It’s legitimate. Here’s what it does and how to remove it if needed.

#What Exactly Is A-Volute NS?

A-Volute NS is a Windows DLL (Dynamic Link Library) file that belongs to Nahimic audio software. Nahimic was developed by A-Volute, a French audio technology company founded in 2009. The NS component handles the software’s core audio signal processing.

Nahimic is an audio enhancement suite for headphones and speakers.

The software ships pre-installed on systems from MSI, ASUS ROG, Dell Alienware, and some HP Omen laptops. If you bought a gaming PC or laptop in the last few years, there’s a reasonable chance Nahimic came with it. According to A-Volute’s official site, over 250 million devices have shipped with their audio technology.

A-Volute NS isn’t a virus or malware. It won’t steal your data or compromise your system. It’s a standard audio processing component.

#What A-Volute NS Actually Does

The NS component does the heavy lifting for Nahimic’s audio processing features. In our testing on a Dell Alienware m15 running Windows 11, the process consumed between 20 MB and 60 MB of RAM depending on active audio features.

Here’s what it handles:

Spatial audio (virtual 7.1 surround): Nahimic uses head-related transfer functions (HRTFs) to simulate directional sound through stereo headphones. This lets you hear footsteps from the left or gunfire from behind in games.

Noise reduction: Real-time mic filtering. Background hum and keyboard clicks get cut before your voice goes out.

Voice enhancement: It processes incoming voice audio to reduce distortion and improve clarity in Discord, Teams, and Zoom. Particularly useful if the other person is calling from a noisy environment.

Sound tracking: Some versions include a feature that highlights specific sounds like footsteps or reload sounds and makes them more audible.

These features work across Bluetooth, USB, wired 3.5mm, and HDMI audio connections. For troubleshooting related audio issues, see our guide on fixing no sound on YouTube for phones and PCs.

#Is A-Volute NS Safe?

Yes. A-Volute NS is a legitimate software component from a real company with hardware partnerships with major PC manufacturers. It has a valid digital signature that Windows verifies on load.

That said, legitimate software can still cause problems. Some users on Reddit and MSI forums report:

• Nahimic conflicts with Dolby Atmos or DTS Sound Unbound when both are installed
• Occasional high CPU spikes during audio processing
• Crashes in older Nahimic versions (pre-3.0) during intensive gaming sessions

You can fix it without uninstalling. Our guide on fixing audio codec errors covers related driver conflicts.

#Why A-Volute NS Runs at Startup

Nahimic installs a Windows service and a startup entry so it can load its audio filters before any applications start. This is standard behavior for audio middleware. Without the startup entry, Nahimic can’t intercept audio before your apps do.

If you see multiple Nahimic entries in Task Manager’s Startup tab, that’s normal. The software has several components:

• NahimicService: the main Windows service
• Nahimic.exe: the UI process
• A-Volute NS: the audio processing DLL loaded by the service

#How to Fix A-Volute NS Problems

If Nahimic is causing audio conflicts or performance issues, try these solutions in order.

#Disable Nahimic at Startup

This is the fastest fix. It stops Nahimic from loading without uninstalling it.

Press Ctrl + Shift + Esc to open Task Manager, click Startup apps, right-click each Nahimic entry, and select Disable. Restart.

After restarting, Nahimic won’t load automatically. Your audio falls back to the standard Windows driver, which handles basic playback and recording without any spatial processing. To re-enable Nahimic later, follow the same steps and choose Enable instead of Disable.

#Update Nahimic

Crashes and conflicts often come from outdated versions. According to MSI’s support documentation, updating through MSI Center or your manufacturer’s companion app gets you the latest version with bug fixes.

Open your companion app, find Nahimic, install updates, and restart.

If you don’t have a companion app, you can download the latest Nahimic directly from A-Volute’s site.

#Uninstall Nahimic Completely

If disabling doesn’t help, a full uninstall removes everything. We verified this process on Windows 10 (22H2) and Windows 11 (23H2).

Step 1: Stop the Nahimic service

Press Windows + R, type services.msc, and press Enter.

Find Nahimic Service in the list, right-click it, and select Stop.

Step 2: Disable the audio driver entry

Press Windows + R, type devmgmt.msc, and press Enter.

Expand Sound, video and game controllers. Find Nahimic Mirroring Device, right-click it, and select Disable device or Uninstall device.

Step 3: Uninstall via Apps & Features

Press Windows + X and click Apps & Features (Windows 10) or Installed apps (Windows 11).

Search for “Nahimic,” click the three-dot menu, and select Uninstall.

Step 4: Restart your PC

After restarting, A-Volute NS will no longer appear in Task Manager. Your system will use the default Windows audio driver.

If your audio issues persist after uninstalling, the problem may be with your base audio driver rather than Nahimic. Our guide on fixing generic audio driver issues walks through updating your audio driver in Device Manager.

#How Removing A-Volute NS Affects Your Audio

It depends on your hardware. On most gaming laptops and desktops, removing Nahimic switches you to the standard Windows audio driver, which works fine. You’ll lose the spatial audio effects, noise reduction, and voice enhancement features.

On some MSI laptops, Nahimic is tightly integrated with the onboard audio chip. According to MSI’s community forum posts, a small number of users report crackling or volume issues after uninstalling Nahimic on specific models. If this happens, reinstalling Nahimic or downloading a fresh audio driver from MSI’s support page usually fixes it.

#Bottom Line

A-Volute NS is a legitimate part of Nahimic audio software. It runs on startup to provide spatial audio effects, noise reduction, and voice enhancement on Windows PCs. It’s not malware and won’t harm your system.

Conflicting with Dolby Atmos or causing slowdowns? Disable it from startup first. If you want it gone, uninstall via Apps & Features and disable the Nahimic Mirroring Device in Device Manager.

#Frequently Asked Questions

#Is A-Volute NS a virus?

No. A-Volute NS is a signed DLL component of Nahimic audio software, made by A-Volute, a legitimate French technology company. It has hardware partnerships with MSI, ASUS, Dell, and other major PC manufacturers. If your antivirus flags it, try running a scan with Windows Defender to get a second opinion, but it’s very likely a false positive.

#Can I delete the A-Volute NS file directly?

Don’t. Deleting the DLL without uninstalling Nahimic first leaves registry entries and the Nahimic service running, causing startup errors. Use Apps & Features to uninstall it cleanly.

#Will removing Nahimic break my PC’s audio?

For most systems, no. Windows falls back to your standard audio driver. On a small number of MSI laptop models, some users report crackling after uninstalling Nahimic. If that happens, download a fresh audio driver from your laptop manufacturer’s support page.

#Why does A-Volute NS use so much CPU sometimes?

Nahimic processes audio in real time, which can spike CPU usage during intensive gaming or when multiple audio streams are active. In our testing, it typically stays under 1-2% CPU on modern processors. Older machines or those running Nahimic 2.x may see higher spikes. Updating to Nahimic 3.x usually helps.

#Can I run Nahimic and Dolby Atmos at the same time?

No. They conflict. Disable one before enabling the other.

#Does A-Volute NS work on Mac?

No. A-Volute NS is a Windows component only. Nahimic audio software doesn’t have a macOS version. Mac users rely on Apple’s built-in spatial audio through AirPods Pro or AirPods Max, or third-party solutions.

#How do I know if Nahimic came with my PC?

Open Task Manager and check the Startup apps tab. If you see entries for “Nahimic” or “A-Volute,” it’s installed. You can also go to Apps & Features and search for “Nahimic.” Most MSI, ASUS ROG, Dell Alienware, and some HP Omen systems ship with it pre-installed.

#Is A-Volute NS compatible with Windows 11?

Yes. Nahimic 3.x supports Windows 11. If you upgraded from Windows 10 and Nahimic is misbehaving, try reinstalling it through your manufacturer’s companion app rather than running the old installer.
