Spectrum is the most recognisable music visualizer format: a row of vertical bars whose heights correspond to the energy in different frequency ranges of your audio. It's fast to render, universally understood, and works beautifully with any genre of music.

Tips & Best Practices
- 1
64 bars is the sweet spot — enough detail without looking cluttered.
- 2
Use Frequency Focus: Bass to make the visualizer pulse with kick drums.
- 3
A dark background (#0a0a0a) with a bright bar colour produces the sharpest contrast.
- 4
Try Response Style: Pulse for percussive tracks — it creates sharp transient spikes.
