DeskBroadcast vs Kleervox

DeskBroadcast turns a webcam and microphone into a software-defined studio, delivering processed video and voice to other apps as virtual camera and microphone devices. Its Look pipeline adjusts warmth, tint, exposure, brightness, contrast, saturation, vibrance, sharpness and background blur. The microphone chain includes AI voice isolation, hum filtering, gating, four-band EQ, compression and auto-leveling. Apps such as Zoom, Google Meet, Microsoft Teams, Slack, FaceTime, OBS and browsers can select its virtual devices. Video, audio and the learned room-noise profile remain on the Mac; the app has no account or media telemetry pipeline and works offline. Software image controls work with every camera, while hardware controls require a UVC-compliant USB webcam. DeskBroadcast requires macOS 14 Sonoma or later and supports Apple Silicon and Intel Macs. The free plan is fully functional but places a “deskbroadcast.com” watermark on output. Pro costs $79, paid once for 3 Macs. Voice isolation adds about 40 ms of latency, and Pro purchases qualify for a full refund if requested within 14 days.

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, while echo cancellation reduces a caller’s voice leaking from speakers back into the microphone. It works as a virtual microphone in apps that let users select 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. Its privacy policy also lists collection of Google sign-in details, usage metrics, installer activity, account state, sign-in history, website and demo analytics, and limited billing data. Free provides one hour of cancellation per day; afterward the microphone works without cancellation until local midnight. New accounts receive a seven-day Pro trial after first successful desktop use, with no card required. Downloads are available for Windows 10, Windows 11, and Linux; macOS is described as coming soon. Windows setup uses VB-CABLE, while Linux creates the virtual microphone automatically.
