How it works
Three steps to a video.
01
Frame-accurate sync
The spectrum analyser runs at your export frame rate. Every bar position is locked to the audio, not interpolated after the fact.

02
Customise the look
Set bar colour, background, and accent. Use your cover art as a backdrop. Tweak bar count and sensitivity to suit the track.

How does the spectrum sync to my audio?+
BeatVisualiser runs an FFT analysis on your audio and maps the frequency data to bar heights on a per-frame basis. Every frame of the exported video is rendered at the correct audio position.
Can I change the bar colours?+
Yes. You can set a primary accent colour, background colour, and bar gradient from the style panel. The free tier has default colours; Pro unlocks full customisation.
What resolution does it export?+
Pro exports 1080p 60fps H.264 MP4. Free exports 720p 30fps with a watermark.
Can I add my cover art to the background?+
Yes. Upload a JPG or PNG and it displays as the background with a blur overlay, keeping the spectrum bars legible.
Does it work for all genres?+
Yes. The FFT analysis and bar sensitivity work across EDM, hip-hop, ambient, classical, and anything else. You can adjust the bar sensitivity to suit low-end-heavy mixes.

Your track deserves a better visual than a waveform screenshot.
