In their own words
Cathar
Cathar is a free audio restoration toolkit for Linux and macOS, with tools to clean, enhance, and level recordings. It accepts WAV, MP3, FLAC, OGG, and M4A files, along with audio tracks inside MP4 and MKV video, and writes WAV, FLAC, or AIFF according to the output filename extension. Restoration options include denoising, de-humming, de-winding, de-clicking, de-clipping, de-reverberation, spectral repair, de-plosive processing, and rustle removal. Enhancement tools handle de-essing, breath removal, voice isolation, and bandwidth extension; loudness and peak normalization prepare delivery levels. The Rust toolkit uses inspectable and tunable DSP stages. Effects can run through the Rust crate or as command-line steps in a media pipeline. An optional machine-learning feature adds a deterministic GRU denoiser with safetensors weights. Optional terminal tools provide an audio player and spectrogram viewer. Cathar is licensed under Apache 2.0 or MIT, and its latest listed release is v0.8.0; the project describes itself as pre-1.0.
