Kleervox vs SoliCall Noise Firewall

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.

SoliCall Noise Firewall is software for call centers and other crowded workspaces that reduces ambient noise and nearby voices so customers are less likely to overhear other conversations. It can remove background voices from agents and supervisors as well as other ambient sounds. SoliCall says the noise reduction can improve transcription and other voice analytics accuracy. The product correlates audio across calls to produce a Noise Map and statistics for finding noisy agents and monitoring call quality. A browser-based dashboard provides live call statistics and aggregated statistics for completed calls. Deployment can be centralized or distributed, and the product can run on-premise without a cloud connection; SoliCall says monitoring data stays on-premise rather than being sent to its cloud servers. SoliCall Connect works with Windows softphones and browser-based softphones, including WebRTC options. PBXMate for Call Centers connects to telephony infrastructure over SIP as a phone proxy or PBX trunk. Pricing is available by contacting SoliCall, which invites prospective customers to request an evaluation version of PBXMate for Call Centers.
