ThorTune is an app for the AYN Thor, a handheld gaming device with two screens, that improves how it sounds and how its screens look, without needing to root the device or fiddle with manual settings. It does two main things. First, it lets you adjust how saturated, or vivid, the colors on both screens appear, using a single slider. The stock screens are tuned to be quite saturated by default, and the app lets you dial that back to something that looks more natural. Second, it improves the device's audio by driving a separate audio engine called JamesDSP, giving the speakers a fuller, clearer sound. The app comes with a ready-made sound preset already tuned specifically for the Thor's speakers, based on work from a well-known retro handheld reviewer. Both of the Thor's screens get their own controls: the main app runs on the top screen, while a smaller quick-controls panel appears on the bottom screen so a player can adjust color or audio settings without leaving whatever game they are playing. That lower panel can be turned off in the settings if not wanted. Setting it up involves downloading the app from the project's releases page, adjusting the color slider on the Display tab, and then following on-screen steps on the Audio tab to install the separate JamesDSP Manager app, turn on the audio engine, and import the recommended sound preset. Once configured, the settings persist even after the device restarts, so it only needs to be set up once. The README is upfront that this project builds on the work of several other open source projects, combining an existing audio engine fork, an existing saturation control approach, and a community-made audio preset into one convenient app. It is released under the GNU General Public License version 2, inherited from those upstream projects, which means any modified versions must also be shared under the same license.
