Restoration Plug-in For Separated Stems

Intrect describes de-artifact as a restoration plug-in for separated stems, AI-generated music, and lossy-compressed audio. They say that it is designed to reduce watery textures, smeared sustains, and high-frequency codec residue. It does not separate stems or measure whether music is AI-generated.

Here's more from the company...

Stem separation tools -- whether classical source separation or modern AI-based models (Demucs, MDX, Spleeter, etc.) -- never deliver fully isolated stems. What you get is the target signal plus residual leakage from other sources, codec-style artifacts, and spectral smearing introduced by the separation network itself. These issues become especially audible when you push the stems in a mix: EQ them aggressively, time-stretch them, or pitch-shift them, and the artifacts surface immediately.

de-artifact is built specifically to clean up these stems; A dedicated neural network trained to identify and suppress separation artifacts in the source signal. Rather than relying on generic spectral processing, the model learns the residual signature left behind by stem separation algorithms and removes it while preserving the integrity of the target source. Works on drums, vocals, bass, and other instrument stems extracted from full mixes.

Key details:
- Eight factory presets, separate harmonic/percussive controls, and a residual monitor to hear what is removed.
- macOS 11+: VST3, AU, CLAP (Apple Silicon and Intel).
- Windows 10 version 2004+: VST3 and CLAP, x64 CPU with AVX2 + FMA.
