The Audio Samplerate Changer is a Magisk module that modifies the system-wide mixer to deliver high-fidelity audio output. It automatically increases USB, Bluetooth, and internal speaker sample rates up to 768 kHz while tweaking kernel tunables to reduce jitter.

I installed this module to see if it actually improves everyday listening, and the jump in clarity on both my Bluetooth earbuds and wired DAC is immediately noticeable. By bypassing Android's default resampling limits, it feeds higher quality data straight to the audio hardware while cutting down annoying playback delays.

Features

Maximized USB audio pushes the HAL driver limits automatically, scaling all the way up to 768 kHz and 32 bits for compatible external DACs.
Smart Bluetooth playback adapts directly to your active wireless codec to prevent double-resampling steps that normally degrade sound quality.
Lower playback jitter happens naturally because the module drops the USB data transfer period to 2000 microseconds instead of the standard 5000.
Disables native compression by turning off dynamic range compression (DRC) and the call screening framework under the audio HAL.

Support & Requirements

Supported Android: Android 14+ (or Android 12+ on custom ROMs/GSIs using a 7.0 audio policy). Not compatible with AIDL-only devices like the Pixel 9 series.
Root Requirement: Magisk.

How to Install

Download the Audio Samplerate Changer .zip file to your device storage.
Open Magisk, navigate to the Modules tab, and tap "Install from storage".
Select the downloaded file, let the flashing process finish, and reboot your phone.
