Spectral

tray and keeps going as long as you want it to.Runs entirely on your machineThere is no account to create, no API key to paste, and no sign-in of any kind. Spectral's local server is bound to your own computer and is not reachable from your network.Finds the audio for youAuto-Detect follows whichever app is actually playing and switches with it. You can also capture a single app, a specific input device, or an ASIO interface with per-channel Left/Right selection.Make it yoursFive layouts — Compact, Stacked, Spectrum-Only, and two Merged panels.Color themes, hex inputs for every surface, and Art Sync to recolor the overlay from each album cover.Glows on cover, cards, text, and spectrum.Animated gradients: Card Sweep and Warp fill.Custom cover images, including animated GIF and video.Save any look as a preset and export it to another PC.Works with what you already useSpectral reads the Windows media session, so it works with anything that reports what it is playing. No integration, no plugin, nothing to configure in the other app. Tested with:Streaming and web players — Spotify, Tidal, YouTube, YouTube Music, SoundCloud, Amazon MusicBrowsers — Chrome, Firefox, Edge, Brave, OperaLocal players — VLC, Windows Media PlayerAudio workstations — REAPER, Bitwig Studio, FL Studio, Ableton LiveAnything else — pick any app as the audio source manually, including Discord and gamesThe only time it goes online is to look up cover art for the track you are playing, from public music databases. Nothing about what you play, capture, or configure is collected or sent anywhere.Rendering runs on your GPU, and Spectral quietly throttles itself when nothing is happening — so it stays smooth without taking the CPU headroom your encoder needs.PresetsStart from a stylized preset, change anything you like, and save it as your own — layout, colors, glows and gradients all travel together, and export carries the whole look to another PC.SpectrumUp to 48 bars with smoothing, bar roundness, gradients, and edge lifts. Frame-rate independent, so it looks identical at 60 fps in a capture and on a 144 Hz monitor.
