Kleervox

Kleervox is a virtual microphone that cleans up call audio with on-device noise and echo cancellation. It suits people who want clearer speech across several call and streaming apps, especially Linux and Windows users. Its daily free allowance is useful for occasional calls, but the Windows cable setup and one-hour cap make it less convenient for everyday use.

Overview

Kleervox processes microphone audio in real time, separating speech from sounds such as keyboard clicks, traffic, fans, and nearby chatter. Echo cancellation also reduces the chance that callers hear their own voices leaking back through your speakers. Because apps access Kleervox as a regular virtual microphone, it can work with Zoom, Google Meet, Microsoft Teams, Discord, Slack, and OBS, provided the app lets you select a microphone.

Noise and echo cancellation run on the device. The maker says microphone audio, recordings, and cleaned output are never uploaded, stored, or inspected. That does not mean the service collects no account data: its privacy policy covers Google sign-in details, daily usage metrics, installer activity, account state, sign-in history, website and demo analytics, and limited billing data. Stripe handles subscription payments, and the maker says it does not store full card numbers.

Key features

• Neural noise cancellation: Filters common household, office, and street sounds while preserving speech. This is the main draw for people taking calls in noisy surroundings.
• Acoustic echo cancellation: Reduces speaker audio feeding back into the microphone, useful when you are not using headphones.
• Virtual microphone: Routes cleaned microphone audio into compatible call and streaming apps. Kleervox supports recording and streaming as well as calls.
• On-device audio processing: Keeps microphone audio and cleaned output off the maker’s servers, though account and usage data are still collected.

Pricing

Kleervox is freemium. The Free plan costs nothing and includes one hour of cleaning per day, neural noise cancellation, acoustic echo cancellation, and a virtual microphone for call apps. When the hour runs out, the microphone keeps working without cancellation until the allowance resets at local midnight. That makes Free a practical fit for shorter or occasional calls, not a dependable choice for long daily meeting schedules.

Pro has custom pricing and is billed monthly in advance, recurring until cancelled. It adds unlimited daily cleaning and priority updates, so it is the relevant option for regular users who cannot risk hitting the daily cap. New accounts get a free seven-day Pro trial, which starts after the first successful desktop use and requires no card. You can cancel or downgrade from the dashboard; Pro remains active through the paid period before reverting to Free.

Platforms

Public desktop downloads are available for Windows 10, Windows 11, and Linux. macOS is described as coming soon, so Mac users should not choose Kleervox expecting a current desktop version. Linux creates the virtual microphone automatically. On Windows, setup guides users through installing VB-Audio’s free VB-CABLE, an extra step that may put off anyone looking for a plug-and-play configuration.

Email support usually replies within one to two business days.

Who it's for

Kleervox is best for Linux or Windows users who make calls or recordings in noisy spaces and want noise and echo reduction to work across compatible apps. The daily free hour can cover lighter use, while Pro’s unlimited daily cleaning is a better fit for people who rely on cancellation throughout the workday. It is a poor fit for Mac users waiting for desktop support, or for anyone who needs uninterrupted free cancellation beyond an hour a day.

Pros and cons

• Pro: On-device audio processing keeps microphone audio, recordings, and cleaned output from being uploaded, stored, or inspected, according to the maker.
• Pro: One virtual microphone can serve compatible call, recording, and streaming apps instead of being limited to a single meeting service.
• Pro: The seven-day Pro trial requires no card and begins only after first successful desktop use.
• Con: Free cancellation stops after one hour each day, even though the microphone continues to work.
• Con: Windows setup requires installing VB-CABLE, while Linux creates the virtual microphone automatically.
• Con: macOS desktop support is not yet available.
• Con: The maker collects account and usage-related data even though it says audio itself stays on-device.

Alternatives

For a broader category comparison, see AI Noise Cancellation Software. Consider these alternatives if their platform or plan fits better:

• Noise Suppression for Voice is a free option for Linux, macOS, and Windows users who want coverage across those desktop systems.
• NVIDIA ShadowPlay is worth considering for Windows users with a supported GPU and GeForce 551.52 driver or later; its listed NVIDIA App plan is free.
• DeskBroadcast is a macOS alternative, with a free plan and a 79.00 USD one-time Pro payment for three Macs.
• NoiseTorch-ng is a free Linux option for systems using PulseAudio or PipeWire.
• NoNoise Mac is a free, open-source option for Mac users.
• Krisp AI Meeting Assistant is an alternative for people who want Android, iOS, or browser-extension support as well as desktop coverage; it has a seven-day free trial with no card required.
• neep offers a 14-day trial and an annual individual or small-team plan at $9 a year, with unlimited use and no daily minutes cap.
• Noise Gator is another free option for Windows and macOS.

Verdict

Choose Kleervox if you use Windows or Linux, want noise and echo cancellation across compatible apps, and value on-device audio processing. Its no-card trial makes Pro easy to evaluate, but the free hour is restrictive for full workdays and Windows requires an extra cable component. Look elsewhere if you need macOS support now, or want free cancellation without a daily cap.
