10 Band parametric EQ with A/B testing functionality. Contour is a simple, no-frills 10-band parametric equalizer for your browser. It saves your settings, supports preset save/load, and makes it easy to import or export profiles for sharing or backup. A built-in visualizer provides a live view of your EQ curve, while the blind A/B testing mode pits all your presets against each other in randomized head-to-head matchups—helping you objectively find the one you actually prefer. Contour works seamlessly with any audio source, including YouTube, Deezer, Spotify, SoundCloud, and more. Disclaimer: Contour is a personal project built to solve a need not addressed by other extensions. It’s provided as-is, with no guarantees of performance, compatibility, or ongoing support.
