how it works

One sink in front of your output.

The preamp.service user service runs preamp daemon. The daemon creates a PipeWire sink named preamp and makes it the default output. Apps play into this sink. The daemon runs the audio through the equalizer and plays it into the output that you select.

outputyour device

When you select an output in the Omarchy audio panel, preamp plays into that output and stays the default.
When you connect headphones that you used before, preamp moves to them, applies their pinned preset and shows a notification.
The volume in preamp is the volume of the output device.
On a laptop with an Omarchy speaker tuning, preamp plays into the tuning, so the tuning still applies.
When the service stops, it gives the default output back to the device that it played into.
Settings live in ~/.config/preamp/config.json. The AutoEq index is cached in ~/.cache/preamp/ for one week.
