Glowtrack Studioby Roobixx Interactive

Audio spectrum video generator

An audio spectrum video shows the music itself: bars, lines or shapes that rise and fall with each frequency. Glowtrack Studio analyses your track with a fast Fourier transform and draws the result frame by frame, so the motion is tightly in sync with the sound — then saves it as an MP4 up to 4K at 60 fps.

Questions

Is the spectrum accurate to the music?

Yes. Each frame is analysed from the actual audio at that moment, so peaks line up exactly with what you hear in the exported video.

Can I use a spectrum with no logo or background?

Yes. Turn off "Show logo" and leave the background empty for a clean spectrum on a dark gradient, or pick a full-screen style.

What video format do I get?

An MP4 file. In Chrome and Edge it uses H.264 video with AAC audio, which plays everywhere and uploads to YouTube, Instagram and TikTok.
