What is LimePulse?

LimePulse is browser-based software that turns music, podcasts and cover art into video: audio-reactive music visualizers, Spotify Canvas loops, Apple Music motion art, video podcasts and live visuals.

LimePulse is software for turning sound into video. You upload a track, an episode or a piece of cover art, choose how it should look, and it renders a finished video file you can post anywhere. It runs in a browser, so there is nothing to install and no graphics card required, and the file it produces is yours to use however you like.

It is built for musicians, producers, labels, podcasters and DJs: people who have audio and need something to look at while it plays.

What can you make with it?

Seven tools sit behind one account. Each one is a different shape of video, and every one of them is covered in its own page of these docs.

ToolWhat it makesTypical use
Music VisualizerA full-length audio-reactive video from a track and its artwork, using one of 42 templatesA single or album on YouTube
Compose, the visualizer builderThe same thing composed from a blank frame, with bars, props, text, images and lyricsA look nobody else has
Canvas, for Spotify CanvasA short seamless vertical loopThe looping visual behind a track on Spotify
Motion, for Apple Music motion artThe same loop at Apple's square and portrait sizesAnimated album art on Apple Music
Podcast, the video podcast studioA video episode where each speaker animates as they talkA podcast on YouTube or Spotify
Stage, the live visuals studioLive visuals that react to a microphone or line-in, with no rendering at allA gig, a DJ set, a venue screen

What does audio-reactive mean?

It means the picture is driven by the sound rather than looping independently of it. LimePulse analyses the audio and extracts what is happening in it frame by frame: the level of every frequency band, the shape of the waveform, the kick, the snare, the hats, the overall energy and brightness. The scene reads those signals, so bars rise on the bass, a vinyl turns at the tempo, and a speaker's halo swells when they raise their voice.

The important consequence is that a visualizer made from your track only fits your track. Read what an audio-reactive video is for the longer explanation of spectrum, waveform and beat sync.

Do I need to install anything?

No. Everything happens in the browser and the rendering happens on our machines, so a laptop that could not export video in a desktop editor can still produce a 4K file here. The one tool that uses your own machine is Stage, because live visuals have to be drawn in the room in real time.

What does it cost?

Building and previewing is free, with no card. You subscribe when you want to download a file without a watermark: $9.99 a month or $99.99 a year, which works out at about $8.33 a month. One plan covers all six tools. See plans and pricing for what is included, or the pricing page.
