Kleervox

Kleervox is a real-time microphone cleanup tool for calls and streams, best suited to Windows and Linux users who want noise and echo cancellation across multiple apps. Its on-device audio processing is a clear privacy advantage, but the free tier’s one-hour daily cap and Windows cable setup are meaningful trade-offs.

Overview

Kleervox processes microphone audio in real time, using neural noise cancellation to separate speech from sounds such as keyboards, traffic, fans, and nearby chatter. Built-in echo cancellation also reduces the chance that callers hear their own voices returning from your speakers. Together, those functions target two common call problems without tying cleanup to a single meeting app.

It appears as a virtual microphone, so it can be selected in apps that allow microphone choice, including Zoom, Google Meet, Microsoft Teams, Discord, Slack, and OBS. That makes Kleervox a flexible option for people who switch between meetings and streaming. It handles microphone input, with recording and streaming support also included.

Noise and echo processing happen on-device. The maker says microphone audio, recordings, and cleaned output are never uploaded, stored, or inspected. Account data is a separate matter: 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: Separates speech from common background sounds, making it relevant for calls from noisy homes, offices, or other shared spaces.
• Acoustic echo cancellation: Reduces speaker audio leaking back into the microphone. This is useful when using speakers rather than headphones, though it is not a substitute for controlling the room’s sound.
• Virtual microphone compatibility: Works with microphone-selecting apps, including the listed meeting, chat, and streaming software. It is less suitable for workflows that cannot choose an input device.
• On-device audio processing: Keeps the audio processing local according to the maker, while account and usage information is still collected as described above.

Pricing

Kleervox uses a freemium model. Free costs nothing and includes neural noise cancellation, acoustic echo cancellation, and a virtual microphone for call apps, but limits cleaning to one hour per day. Once that allowance runs out, the microphone continues to work without cancellation until the limit resets at local midnight. That is enough for shorter or occasional sessions, but a long workday of calls can outlast it.

Pro has custom pricing and is billed monthly in advance on a recurring basis until cancelled. It provides unlimited daily cleaning and priority updates, so it is the better fit for regular users who cannot work around the Free cap. New accounts receive a free seven-day Pro trial after their first successful desktop use, with no card required. Users 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. Linux creates the virtual microphone automatically. Windows setup requires installing VB-Audio’s free VB-CABLE, adding a step that may deter users who want a simpler start. The web platform is included, while macOS is described as coming soon rather than a current desktop download. Email support usually replies within one to two business days.

Who it's for

Kleervox is a sensible choice for Windows and Linux users who want one microphone cleanup tool across calls, chat, and streaming apps, particularly if keeping audio processing on-device matters to them. The Free plan suits people with occasional or shorter daily sessions. Users who need all-day cancellation should consider Pro, while anyone unwilling to install VB-CABLE on Windows or seeking a current macOS desktop download should look elsewhere.

Pros and cons

• Pros: On-device noise and echo cancellation keeps audio processing local; support for a virtual microphone extends to several named call and streaming apps; the seven-day Pro trial requires no card.
• Cons: Free cancellation stops after one hour each day; Windows requires a separate VB-CABLE installation; Pro renews monthly until cancelled and its price is custom.

NoiseTorch-ng is a free Linux option for users of PulseAudio or PipeWire. NoNoise Mac is a free, open-source option for macOS users.

NVIDIA ShadowPlay is a free Windows choice for users with a supported GPU and GeForce 551.52 driver or later. NVIDIA Broadcast is another free option when AI audio and video effects for an RTX PC or workstation are the priority. Noise Suppression for Voice is a free alternative for Linux, macOS, and Windows. SoliCall Noise Firewall has custom pricing for its call-center offering. Alt Denoiser is a free alternative for Windows, macOS, and Linux.

Verdict

Choose Kleervox if you want real-time, on-device noise and echo cancellation across microphone-selecting apps on Windows or Linux, and its setup and daily limits fit your routine. The free allowance and no-card trial make it accessible, but the one-hour cap is restrictive for heavy use and Pro pricing is custom. Look elsewhere if you need macOS now, unlimited free cancellation, or a Windows setup without a virtual cable.
