wtf is metaphor-refantazio-complete-audio-patch?

This project is an unofficial fix for two audio problems in the game Metaphor: ReFantazio when it is played on a Mac through CrossOver or Wine, tools that let Windows games run on macOS. The first problem is that character dialogue during cutscenes can sound quiet, hollow, or poorly balanced, because the game sends audio meant for multiple speakers to a normal two speaker setup incorrectly. The second problem is that the game's audio can suddenly cut out entirely and randomly during play, caused by the game occasionally asking Wine for a larger chunk of audio data than it can provide at that exact moment. The patch fixes the dialogue issue by properly mixing the multichannel audio down to two channels before it reaches the speakers. It fixes the random silence issue by having the game accept a smaller amount of audio data when the full amount is not available, rather than stopping the audio stream entirely. The dialogue fix builds on an earlier open-source project by a different author, and this patch adds the cutout fix along with logging, testing, and packaged releases on top of that earlier work. Installation can be done through a guided installer that copies the needed files into the game's Wine bottle and configures the correct settings automatically, or through a manual process of copying four files next to the game's executable and changing a Wine library setting by hand. The patch does not touch the game's saves, executable, or other unrelated settings, and it can be removed the same way it was installed. So far it has only been tested on one specific Mac model and one specific version of CrossOver, so the author notes that other hardware and software combinations may or may not work. Building the patch from source requires CMake and a Windows cross compiler on a Mac or Linux machine.
