PeakNits – HDR & OLED music visualizer

Visualize the audio of any tab with thin, bright lines on true black. HDR, Rec.2020, native refresh rate.

Skopiuj cały blok: PeakNits turns the audio of any browser tab into a live visualization built for modern OLED and HDR displays. Play music anywhere – YouTube, Spotify Web Player, SoundCloud, web radio – click the PeakNits icon on that tab, and the visualizer opens next to it. Drag it to your best monitor, press F for fullscreen and enjoy. WHY IT LOOKS DIFFERENT • True black: the background is exactly zero, so OLED pixels stay switched off. Fading trails return to real black, never to grey. • Thin, razor-sharp lines rendered live at your display's native resolution – no video, no compression, no banding. • Your monitor's native refresh rate: 120, 144, 240 Hz and beyond. • HDR: on an HDR display highlights shine brighter than SDR white (WebGPU extended range). The HDR peak slider lets you find your panel's maximum brightness. • Wide colour: Display-P3, and Rec.2020 palettes in HDR mode. SIX MODES • Silk – 64 strands twisted into a ribbon, each lit by its own frequency band • Waterfall – the spectrum history in perspective, like a hologram • Scope – a CRT-style XY oscilloscope where the beam glows brighter as it slows down • Halo – symmetric rings with shockwaves on every beat • Warp – star streaks that show off fast, sharp motion • Snake – a peak-brightness test: a few bright snakes that cover a fraction of the screen, so OLED panels can hit full HDR brightness FEATURES • Five palettes with smooth transitions, auto-cycling of modes and palettes • Auto gain adapts to quiet and loud sources • Per-mode line width, exposure and trail, remembered between sessions • Keyboard shortcuts for everything (press K) • Burn-in friendly: controls and cursor hide automatically, nothing stays still PRIVACY Audio is analyzed locally in your browser and is never recorded, stored or sent anywhere. No analytics, no accounts, no tracking. A tab is captured only after you click the PeakNits icon on it. Also available as a website at https://peaknits.net (demo, audio files and microphone input). Best experience: Chrome or Edge on Windows 11 with HDR enabled, or macOS, on an OLED display.
