Kleervox

Kleervox reduces background noise and speaker echo during calls using real-time processing on the device. Its neural noise cancellation separates speech from sounds such as keyboards, traffic, fans and chatter. Echo cancellation reduces a caller’s voice returning from speakers into the microphone. It appears as a virtual microphone in apps where users can choose a microphone, including Zoom, Google Meet, Microsoft Teams, Discord, Slack and OBS. The maker says microphone audio, recordings and cleaned output are not uploaded, stored or inspected. The Free plan includes one hour of cancellation per day; after that limit, the microphone continues without cancellation until local midnight. New accounts receive a seven-day Pro trial after their first successful desktop use, with no card required. Desktop downloads are available for Windows 10, Windows 11 and Linux; macOS is described as coming soon. Windows setup uses VB-Audio’s free VB-CABLE, while Linux creates the virtual microphone automatically. The privacy policy also lists collection of sign-in details, usage metrics, installer activity, account state, sign-in history, website and demo analytics, and limited billing data.

Kleervox provides on-device noise and echo cancellation through a virtual microphone, with a daily limit on the free plan. Desktop downloads are listed for Windows and Linux, while macOS is not yet available.

Kleervox suits people who want noise and echo reduction for calls in apps that allow microphone selection. It is available on Windows and Linux desktop systems.

Kleervox is a real-time microphone cleanup tool for calls and streams. It is best suited to Windows and Linux users who want noise and echo reduction across apps, rather than a tool tied to one meeting service. Its on-device processing is a clear privacy strength, but the free plan’s one-hour daily cap limits its appeal for regular use.

Overview

Kleervox presents a virtual microphone that processes audio as it comes in, using neural noise cancellation to separate speech from sounds such as keyboards, traffic, fans, and chatter. Echo cancellation addresses a different nuisance: the caller’s voice leaking from speakers back into the microphone. Together, those functions target common call problems without requiring a particular call app.

Audio processing runs on-device. The maker says microphone audio, recordings, and cleaned output are never uploaded, stored, or inspected. That is a meaningful distinction for people concerned about the audio itself, though it is not a no-data service: the privacy policy covers Google sign-in details, usage metrics, installer activity, account state, sign-in history, website and demo analytics, and limited billing data. Stripe processes subscription payments, and the maker says it does not store full card numbers.

Key features

• Neural noise cancellation: Aims to keep speech distinct from everyday background sounds. It is relevant to callers working near traffic, fans, keyboards, or other people, but no specific performance guarantee is provided.
• Acoustic echo cancellation: Reduces the return of a caller’s voice from speakers into the microphone, addressing feedback that noise filtering alone does not solve.
• Virtual microphone: Apps that allow microphone selection can use Kleervox, including Zoom, Google Meet, Microsoft Teams, Discord, Slack, and OBS. That breadth makes it useful for mixed call and streaming workflows, though compatibility depends on the app offering that selection.
• Recording and streaming: Recording support, streaming support, and voice isolation are included among its capabilities, extending its use beyond meetings.
• On-device audio handling: Keeping cancellation on the device can suit users who do not want microphone audio sent to a service for processing. Account and usage data still form part of the service’s privacy footprint.

Pricing

Kleervox uses a freemium model. 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. Once the hour is used, the microphone continues without cancellation until the allowance resets at local midnight. That is a workable option for occasional calls, but not a dependable all-day allowance for people in frequent meetings.

Pro has custom pricing, is billed monthly in advance, and recurs until cancelled. It provides unlimited daily cleaning and priority updates, removing the Free plan’s central constraint for regular users. New accounts get a free seven-day Pro trial after their first successful desktop use; no card is required. Users can cancel or downgrade from the dashboard, and Pro remains active through the paid period before reverting to Free. The monthly renewal makes it important to cancel or downgrade if ongoing use is no longer wanted.

Platforms

Public desktop downloads cover Windows 10, Windows 11, and Linux. macOS is described as coming soon, so Mac users should not choose Kleervox expecting a current desktop release. Linux creates its virtual microphone automatically. Windows setup requires installing VB-Audio’s free VB-CABLE, an extra step that may be unwelcome to anyone looking for a simpler microphone setup.

Email support usually replies within one to two business days. That is a reasonable route for non-urgent setup questions, but not an immediate-help option.

Who it's for

Kleervox is a good fit for Windows or Linux users who want one microphone-cleanup layer across calls, streaming, and recording apps, especially if keeping audio processing on-device matters. The free tier suits light or intermittent use; the Pro trial lets a new user assess the unlimited daily allowance before deciding whether a recurring plan fits. People who regularly need more than an hour of cleaned audio each day should compare Pro’s custom pricing with alternatives, while macOS users need another product for now.

Pros and cons

• Pro: Noise and echo cancellation address both background sound and speaker-to-microphone feedback.
• Pro: The virtual microphone works across many named call and streaming apps, rather than only one meeting service.
• Pro: Audio processing stays on-device, and the seven-day Pro trial requires no card.
• Con: Free cleaning stops after one hour each day, which can interrupt regular users’ workflow.
• Con: Windows users must install VB-CABLE, while Linux sets up the virtual microphone automatically.
• Con: There is no current macOS desktop download, and Pro’s custom price makes its ongoing cost harder to judge upfront.
• Con: Audio is not uploaded, but the service still collects several categories of account, usage, installation, and analytics data.

Verdict

Choose Kleervox if you use Windows or Linux and want on-device noise and echo cancellation that can serve multiple call and streaming apps. Its strongest case is the combination of broad virtual-microphone compatibility and audio processing that stays on your device. Look elsewhere if you need macOS support, more than an hour of free daily cleaning, or a clear Pro price before committing to a monthly plan.
