What it does

Your music but made visible

LYRA listens to what is currently playing on your devive. so it reacts to anything you play and renders particles while it does that

Nebula

A choice between one million particle to react with the bass and ignite an explosion, also known as the supernova

upercluster

A spiral galaxy with volumetric dust arms and a vortexing core. Track changes send a density wave through it and the hardest drops, fire an impulse shockwavetrough the whole thing

It hears everything

LYRA Reacts to your system audio from any source. If Spotify (or any app) is playing, LYRA reads the song, artist and artwork and recolors the whole scene to match the album by its cover

In your language

Choose between English, Español, Deutsch, Français, Português and Italiano. LYRA follows your Windows language automatically, and you can switch any time in LYRA Settings

Graphic choice

Pick a particle count and render resolution that fit your GPU. great for big and 4K screens. Launches in fullscreen, and keeps your PC awake while the music plays

How beat gets detected

A custom audio engine tracks onsets, tempo and drops with low latency (hopefully), so the visuals land on the beat. Different stems get detected: kicks, snare, bpm, e.t.c.

Stream overlay for OBS

A transparent browser source for OBS and Streamlabs. A now-playing card plus an album-colored, beat-reactive scene, fully customizable, with donation alerts and beta mic reactivity. One URL, no plugins

Live desktop wallpaper

Run LYRA behind your desktop icons on Windows. Pick one monitor, a span, or all of them. It steps back when a fullscreen game is in front, and a global hotkey gets you out

Cast to your TV

Mirror LYRA to a Chromecast or Android TV on your network, with nothing to install on the TV. Hit C to start beaming the scene to the big screen

Support & known issues

Most answers for an issue you can find here. Browse below, or ask the assistant in the corner (not an AI assistant)

LYRA visualises your default Windows playback device. If your sound is going to Bluetooth headphones, a headset, or a second output, LYRA may be listening to the wrong one.
  1. Open Settings (the gear in the bottom dock) and click Re-detect audio.
  2. If that doesn't catch it, set the device you're actually hearing as the Default output: right-click the volume icon → Sound settings.
  3. You can also press R to force a re-acquire.
When it's working, the status reads "hearing audio ✓".
Two sliders in Settings do most of the work, and one fix lives outside LYRA:
  1. Lower the Render resolution (try Balanced or Performance) — this is the biggest lever, especially on large or 4K screens.
  2. Drop the Particle count to Medium or Low.
  3. Update your GPU drivers. An out-of-date driver is a very common cause of stutter — a clean driver update has fixed it for testers.
That's SmartScreen flagging an app it hasn't seen before. LYRA is a free, unsigned hobby project (code signing certificates are expensive), so it has no reputation yet — not because anything's wrong.
  • Click More info → Run anyway.
  • Prefer to verify first? The source is fully public on GitHub.
LYRA needs a WebGPU-capable GPU with current drivers.
  1. Update your graphics drivers and reboot.
  2. Make sure you're on 64-bit Windows 10 or 11.
  3. If you have both an integrated and a dedicated GPU, make sure LYRA runs on the dedicated one (Windows → Graphics settings).
LYRA reads now-playing info from Windows itself (the same data behind the media popup on your volume flyout).
  • If the little media controls don't appear when you hover your volume icon, that app isn't reporting to Windows — and LYRA can't read it. The audio visualisation still works.
  • Spotify is prioritised when it's running. Album-art coloring needs the source to provide artwork (Spotify does).
Windows doesn't always tell apps when the default output changes. Open Settings → Re-detect audio (or press R) and LYRA re-pins to your current device. LYRA also tries to recover on its own after a few seconds of unexpected silence.
Yes — completely free. LYRA is a non-commercial hobby project, not a product.
No. There's no login of any kind. The visualizer reacts to whatever audio your PC plays, and song info comes from Windows. If Spotify happens to be playing, LYRA shows the track and album color — but it's optional, and no Premium is required.
No accounts, no telemetry. Now-playing info stays on your machine. LYRA writes a local log to %AppData%/lyra/lyra.log so you can send it if you hit a bug — that's it.
Not right now. LYRA reads now-playing from Windows-specific APIs, so it's Windows 10/11 only for the moment.
Everything you need is in the dock at the bottom, but for keyboard fans:
  • G / N — Galaxy / Nebula scene
  • 1 / 2 / 3 — particle tier (250k / 500k / 1M)
  • R — re-acquire the audio device
  • D — toggle the audio-analysis debug overlay
Possibly. As long as it supports WebGPU and has current drivers, drop the particle count to Low and the render resolution to Performance and give it a try.
