PPI Analyzer

About

Your presets can mislead your LUFS meter. Even when two tones register identical LUFS levels, their perceived loudness can vary greatly—dense distortion and clear sparkle affect the ear differently. PPI Analyzer evaluates perceived loudness using a Bark-band psychoacoustic model and provides the precise dB adjustment needed for every preset. It is compatible with Quad Cortex, Helix, Kemper, and all amp simulators. The tool operates directly in your browser, with no installation, account, or internet connection required. A single file grants you access, including updates for life.
