Alt Denoiser
Alt Denoiser is a real-time audio noise suppression plugin based on DeepFilterNet.
What Alt Denoiser is
Alt Denoiser is a real-time audio noise suppression plugin based on DeepFilterNet. It is free and open source, with binaries for Windows, macOS, and Linux in VST3, VST2, AU, LV2, and Standalone formats. DeepFilterNet3 models are included, so you do not need to download a model separately. The plugin accepts any host sample rate and resamples automatically. Its interface keeps adjustment simple, with an attenuation knob 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 also describe fixes for stutter and dropouts in EqualizerAPO and DAWs at standard buffer sizes. Linux build guidance covers Ubuntu/Debian, Fedora, and Arch; compiling from source requires CMake 3.15 or later, Rust, and a C++ compiler. The project is licensed under GPLv3, and GitHub Issues are available for questions and bug reports.
