NoNoise Mac

NoNoise Mac is a menu-bar utility for cleaning microphone sound during calls, recordings, and streams. It suits Apple Silicon Mac users who want local processing and more speech controls than a basic noise gate. Its strongest case is a free, open-source tool with broad routing options; its narrower case is anyone on Intel hardware or a non-Mac platform.

Overview

NoNoise Mac removes background noise and room echo in real time. DeepFilterNet3 is compiled to CoreML, with processing handled by the Apple Neural Engine and Metal. The project says audio stays on the Mac, without telemetry or an account, so it is a sensible choice for users who do not want voice audio sent to a cloud service.

The app requires an Apple Silicon Mac, such as an M1 or newer, and does not support Intel Macs. It is a macOS application rather than a cross-platform service. Installation uses a package that installs both the app and its virtual microphone driver. Because the installer is not notarized, macOS may require choosing Open Anyway in Privacy & Security before setup can continue.

Key features

Modes and voice shaping

Meeting, Podcast, Tutorial, and Custom modes provide useful starting points, while suppression and voice-polish controls allow adjustment. Broadcast Voice can add presence and de-essing, and Mouth Noise applies de-plosive and de-click suppression. These controls make NoNoise Mac better suited to spoken-word calls and recordings than a single on/off filter, although they remain focused on voice cleanup rather than full audio production.

Microphone routing

Processed microphone audio is exposed through the NoNoise Mic virtual microphone for selection in Zoom, Meet, Discord, OBS, Slack, and QuickTime. Input support covers built-in and USB microphones, plus XLR microphones connected through an interface. That combination fits remote meetings, podcasting, streaming, and screen recording without tying the app to one conferencing platform.

Incoming audio and automation

Clean Incoming / Guest denoises system audio in real time, including incoming speech, but requires macOS 14.4 or later. Configurable global hotkeys, a nonoisemac:// URL scheme for Stream Deck or shell actions, and a bundled CLI make it more practical for repeatable workflows than a menu-bar control alone.

Offline file cleanup and updates

The CLI can clean audio files locally. Video-container support is planned separately, so the current file workflow should be treated as audio-focused. Sparkle checks for stable releases at launch and daily and can prompt for updates, reducing the need to track releases manually.

Pricing

The Free plan costs free. It is open source under the MIT license and includes the application without a paid tier, trial period, renewal, seat charge, or usage quota stated. That makes it an unusually straightforward option for individual Mac users and small production setups. The trade-off is that eligibility is defined by hardware and operating-system requirements rather than by a cheaper feature tier: Intel Macs cannot use it, and Clean Incoming / Guest needs macOS 14.4 or later.

Platforms

NoNoise Mac supports macOS on Apple Silicon Macs, including M1 and newer systems. Intel Macs are excluded. The downloadable package installs the virtual microphone driver alongside the app, and the non-notarized installer can require manual approval in macOS Privacy & Security.

Who it's for

Choose NoNoise Mac if you make calls, streams, tutorials, podcasts, or recordings on an Apple Silicon Mac and want real-time noise and echo reduction without an account or cloud processing. Its voice modes, mouth-noise controls, virtual microphone, incoming-audio cleanup, and automation hooks suit users who move between several audio applications.

Look elsewhere if you need Windows or Linux support, Intel compatibility, or a notarized installer with no security prompt. Users seeking broad multitrack editing will also need a separate audio tool; NoNoise Mac is principally a live cleanup and routing utility.

Pros and cons

Pros

• Local processing: The project says audio remains on the Mac, with no telemetry or account.
• Flexible speech controls: Four modes, voice polish, Broadcast Voice, and Mouth Noise target different speaking situations.
• Wide app routing: A virtual microphone works with major meeting, streaming, recording, and collaboration apps.
• Automation support: Hotkeys, Stream Deck or shell URL actions, and a bundled CLI support repeatable setups.
• No purchase barrier: The free, MIT-licensed plan has no stated trial, renewal, seat, or quota limits.

Cons

• Apple Silicon only: Intel Mac owners cannot run it.
• macOS-only: It offers no Windows or Linux version.
• Installer friction: The package is not notarized and may require an Open Anyway approval.
• Incoming-audio requirement: Clean Incoming / Guest needs macOS 14.4 or later.
• Audio-file scope: Video-container cleanup is planned separately rather than included in the current CLI workflow.

Alternatives

DeepFilterNet is the better fit if you want the underlying free, open-source noise-reduction project across Linux, macOS, and Windows rather than a Mac menu-bar package.

Kleervox suits users who need Linux, Windows, or web access and can work within a free plan capped at one hour of cleaning per day, with a paid Pro option.

DeskBroadcast is worth choosing for a macOS broadcasting workflow where a one-time Pro purchase covers three Macs; its free edition carries a video watermark.

Noise Blocker is a Windows alternative with a 30-day business trial for up to 20 employees or computers, subject to request and approval.

Noise Gator is a free, MIT-licensed standalone choice for both macOS and Windows.

NoiseTorch-ng is the Linux-focused option, supporting PulseAudio or PipeWire.

NVIDIA ShadowPlay fits Windows users with a supported GeForce setup and the required driver.

RNNoise is a free Linux-oriented project under the BSD-3-Clause license.

Verdict

NoNoise Mac is a strong recommendation for Apple Silicon users who want free, local microphone cleanup with practical voice shaping, virtual-microphone routing, and automation. Choose it for privacy-conscious calls, streams, and recordings; look elsewhere if you need Windows, Linux, Intel Mac support, or a notarized installation experience.
