This thread is for outputs.
What it's for: making the right sound follow the right device. Every setting belongs to the output you tuned it on — the EQ, the preset, the Tone, the DSP rack, the Room and the leveling — and comes back the moment you switch to it. Bluetooth headphones show their battery beside the output.
How it works: FluidEQ follows Windows' own ID for the device, not its name, so a rename or a re-plug changes nothing. A second output plays what you hear on other devices at the same time, each with its own sound and level; on the FluidEQ Engine it plays straight from the engine, and every delay is shown. Games can have a sound of their own too, under Game presets, switched when the game comes to the front and put back when it closes.
