This thread is for headphone corrections and presets.
What it's for: starting from a measurement instead of from scratch. 6,229 headphones and 12,594 published curves ship offline from OPRA, the community directory of headphone EQ profiles, grouped by brand and credited to whoever measured them — oratory1990, the AutoEq project, Rtings.
How it works: a published correction is applied as a layer of its own, beside your bands, with its own strength and switch — so clearing your EQ does not throw it away. For anything not in OPRA, Squiglink works as a guided import: export the EQ text there, paste it here, preview the curve, and it becomes editable bands. A whole output's tuning exports as a .fluideq file and imports back onto the output you are listening to.
The library can update on its own, and every release carries the current database with it.
Ask here about corrections for your model, Squiglink imports, and sharing chains.
Renamed and rewritten for 1.4: this tab was AutoEQ, and the data was AutoEq's. OPRA replaced it — the tab is EQ Presets now.
