tl;dr: EasyEffects, a PipeWire-based audio processing app for Linux, can dramatically improve laptop speaker quality by applying equalization and other effects—essentially replicating the software tuning that makes MacBook and Dell XPS speakers sound good. Users can drop community-made presets (like JackHack96's Advanced Auto Gain) into a config directory and toggle them via the system tray. The author argues Linux distributions, desktop environments, and OEMs should integrate EasyEffects and ship laptop-specific presets by default.
