Mastering Assistant chains three stages on the master bus: DeepFilterNet 3 for residual hum and bleed cleanup, matchering 2.0 for spectral and dynamic matching against a reference, and a brick-wall true-peak limiter we wrote ourselves in nih-plug. You pick the LUFS target (-14 for Spotify, -16 for Apple Music, -9 for club).

Each block names the technique, the number, and the output. If a feature can't carry a number, it doesn't ship.

A 200-word account of the model, the runtime, the data path, and the honest scope. Read this before you buy.
Mastering Assistant chains three stages on the master bus: DeepFilterNet 3 for residual hum and bleed cleanup, matchering 2.0 for spectral and dynamic matching against a reference, and a brick-wall true-peak limiter we wrote ourselves in nih-plug. You pick the LUFS target (-14 for Spotify, -16 for Apple Music, -9 for club). The render lands in 1.8 s on an M2 Air for a four-minute song. Every stage can be bypassed; the A/B against source is single-key. The output goes through the host's bounce or directly to a 24-bit WAV next to the project. The model is good at full-band mixes; for a stems-out mastering chain (vocal stems separated from drums separated from synths) the standalone iZotope Ozone 11 Advanced still has the better dynamic EQ pre-stage.
Dated, terse, one fact per line. No 'general improvements'.

Mastering Assistant is tested in Cubase, Logic Pro, Ableton Live, Studio One, Bitwig, Pro Tools, REAPER as CLAP, VST3, and AU. The build is code-signed with Apple Notarytool on macOS and EV-signed on Windows (DigiCert).
No. Activation runs once over the internet, then the plugin runs offline. Two activations per license.
The model file is fetched from the SONICHAOS lab CDN and hot-swapped without a plugin reinstall. You can pin a version in Preferences if a session needs to stay bit-stable.
-14 LUFS (Spotify), -16 LUFS (Apple Music), -9 LUFS (club PA). Custom targets between -24 and -6 LUFS are accepted, with a warning above -8 LUFS.
Yes. Drop a 24-bit WAV or paste a YouTube URL; matchering 2.0 matches across 32 perceptual bands. The reference is hashed locally — we don't store it.
For stems-out mastering (vocal stems separated from drums separated from synths), iZotope Ozone 11 Advanced still has the better dynamic EQ pre-stage. Use Mastering Assistant on a finished stereo mix.
