Override Android's default volume steps. Set your own custom step count (1-1000). No root required. Includes 6000+ headphone sound profiles from AutoEQ, updated automatically.
Android defaults to 15-25 volume steps. 32steps lets you set your own count by splitting each system step into smaller sub-steps using a gain offset through Android's DynamicsProcessing API (falls back to Equalizer on older devices). An accessibility service intercepts your volume buttons, and a foreground service keeps it running in the background. Works across all apps.
Pick your headphones from 6000+ models and the app corrects the sound based on measured data from AutoEQ. Save presets with different headphones and step counts. The headphone database updates automatically.
