Android App Granular Volume Fixes Too-Loud Minimum Volume

Granular Volume, an open-source Android app, uses DynamicsProcessing or LoudnessEnhancer APIs to apply negative gain below the system's minimum volume step. Unlike apps that only add more volume steps, this approach actually lowers the floor by attenuating the signal after the slider. The app is now buildable reproducibly for F-Droid, solving a separate engineering challenge.
