This hack mixes every individual channel at 16-bit audio before downsampling everything to 8-bit audio as opposed to the default m4a mixer which mixes every channel at 8-bit audio (blame the GBA's DAC!)

• This greatly reduces the number of quantization/rounding errors that pop up during the mixing process, making the classic GBA "background hiss" much quieter while making Shogo Sakai's music sound crispier than ever! Results seem even better when played back on actual hardware. Enjoy!!

元のミキサーの様にチャンネルを8-bitでミキシングすることではなく、それぞれのチャンネルを16-bitでミキシングしてから最終の8-bit段階にダウンサンプリングする。

• この調整はクォンタイズすることによる誤差を減らし、GBAの特徴的なノイズ音を下げる。酒井省吾さんの曲をより綺麗に聞こえる！エミュレータよりハードの方の改良が大きいらしい。

You may hear occasional popping in-game after patching your ROM, for example while saving your game. Throughout 100+ hours of testing, these same pops were heard while playing the original Japanese release, making us fairly confident this hack isn't the cause. It's possible these audio glitches were covered up by the original mixer's background noise and are now easier to hear with clearer audio. Please don't hesitate to report any bugs, but just keep in mind there's only so much you can do with the GBA's limitations!

If your ROM is a Fan Translation, this patch does modify the RNG used by MOTHER 3 and will most likely give you unexpected results! Because of that, any TAS recordings of MOTHER 3 will be broken by this hack. You have been warned!!

• 100% compatibility with ALL Fan Translations! [versions 1.2 and below will cause occasional slowdowns with this hack, regardless of the language]
• Compatible with the original Japanese release of MOTHER 3
• Compatible with other ROM hacks, such as Claus' Journey [this is an EXPERIMENTAL feature; be aware of potential bugs!!]
• Customize your game's sample rate for higher-quality sound effects, including Lucas' clean electric guitar during battles
• Save backup copies of your game before patching
• Easily undo/remove the HQ sound patch from your game
• Read the source code behind this patch
• Windows, macOS, and Linux support (64-bit only)

Download the patcher from the Releases section of this repo (or build using Maven) and either load your ROM with the "Open" button or drag-and-drop your ROM into the patcher. After you indicate whether your copy of MOTHER 3 is an original Japanese release or a Fan Translation, you'll be able to apply the hack to your game. Simple as!
