Granular Volume

Granular Volume is an Android app providing a floating volume dial that applies a flat attenuator on the device's mixed audio output, enabling volume control below Android's default minimum level. It works without root or ADB, requires standard audio permissions and overlay permission, and offers 7 attenuation steps from 0 to -30 decibels, plus the regular volume range above the device minimum. It addresses Android's design limitation where the lowest volume step is still too loud for some users.
