Noise Gator vs SoliCall Noise Firewall

Noise Gator processes microphone audio in real time to reduce noise, then sends the cleaned signal to a virtual audio device for other apps. It is free under the MIT license and runs on Windows and macOS. Discord, Teams, and Zoom are named as apps that can use the virtual device as a microphone input. DeepFilterNet is the default denoising engine, with dual-pass RNNoise as a lighter fallback. The audio pipeline also includes a highpass filter, suppression control, a voice-activity-driven noise gate, three-band EQ, and automatic gain normalization. Bluetooth headset audio is supported, and the device menu refreshes when devices connect or disconnect. The app can install VB-Cable on Windows or BlackHole on macOS automatically. Prebuilt binaries are available from GitHub Releases; the ZIP includes the executable and ONNX Runtime DLL. DeepFilterNet’s runtime and an approximately 8 MB model download on first use, with SHA256 verification. Settings are saved to a TOML file for the next launch, and headless mode supports scripted or server use. The latest listed release is v0.1.2. Building from source requires stable Rust 1.85 or later, plus MinGW-w64 or MSVC on Windows.

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.
