It is free and open source, with precompiled downloads for Windows, macOS and Linux in VST3, VST2, AU, LV2 and Standalone formats. DeepFilterNet3 models are bundled, so no separate model download is needed. The plugin accepts any host sample rate and resamples automatically. Its interface has an attenuation control and input and output RMS meters. Version 1.0.2 supports mono-to-mono, stereo-to-stereo and mono-to-stereo routing, and declares 1,920 samples of latency for startup and reset FIFO prefill. Release notes mention fixes for stutter and dropouts in EqualizerAPO and DAWs at standard host buffer sizes. Linux build instructions cover Ubuntu/Debian, Fedora and Arch; building from source requires CMake 3.15 or later, Rust and a C++ compiler. The project is licensed under GPLv3 and directs questions and bug reports to GitHub Issues. macOS binaries target macOS 14.0 and later.
