The High Performance DAC is an open-source software developed by OIakera. It is a Magisk module that enables the “High Performance DAC” mode of Qualcomm’s WCD9xx DAC.
What it does
Every phone powered by a Qualcomm processor has a built-in WCD9xx Audio DAC, but it’s rarely configured to be used to its full potential by OEMs1. This module maximizes the power of Qualcomm’s WCD9xx DAC to get the best audio quality possible. By enabling High-Performance Mode, the audio quality of Qualcomm-powered devices will not only receive a boost in volume but will sound more clear and crisp.
Installation
Just flash via Magisk/KernelSU and reboot.
