Match to

Pick what Match EQ should target. Original = no matching (chain still runs). Reference 1/2/3 = drop your reference tracks (1-3 — averaged when more than one). Genres = release-style presets (also set the loudness target).

Release target

A loudness goal to aim near — a dB or two off is normal, and platforms simply turn tracks up or down to match. Not a pass/fail limit. Custom sets the LUFS target without any physical-delivery constraints. The other targets carry mono/ceiling expectations the AI Engineer will respect when AI Master runs. Not affiliated with these platforms; targets are publicly documented.

Simulate on

Near Field Monitors (8″) — Flat 8-inch nearfield reference — honest low end, no coloring.

A rough approximation of a typical device — every real device differs. A sanity check, not a measurement, and never baked into the download.
