About Stem Sculpture

Stem Sculpture splits your mix into four frequency-based layers, roughly where vocals, drums, bass and everything else sit, and gives each its own visual form: ribbons for the vocal range, shards for drum hits, rings for the bass, and drifting dust for the rest. Each form moves with the energy in its own band. This is an estimate from the mixed audio, not true stem separation. Frequency bands overlap, so a bright synth can move the vocal ribbons and a low tom can move the bass rings. On most mixes the result still reads clearly: when the bass drops out, its rings settle; when the drums come in, the shards wake up, so arrangement changes become visible. It suits producers who want to show how a track is built, and anyone who wants each part of the mix to have its own visual voice.

How it works

During the offline analysis, band-pass filters estimate four energy curves from the mix: vocal range, drum transients, bass and the rest. No neural separation is involved, and nothing leaves your browser. Each stem is assigned a sculptural primitive generator: vocals use a surface-of-revolution with waveform-driven profiles, drums use convex hull geometry with onset-triggered deformations, bass uses a metaball system with energy-driven radius, and melody uses an L-system with harmonic-driven branching rules. All sculptures share a common coordinate space and interact through proximity-based lighting effects. The composite is rendered with PBR materials and cinematic post-processing.

Science Behind This Effect

Stem Sculpture maps frequency-band energy estimates to 3D geometry, leveraging psychoacoustic critical band theory to give each band its own visual form.

Frequently Asked Questions

Does it really separate stems?+
No. It estimates energy in four frequency ranges of the mixed audio, which works well for visuals but is not source separation. Instruments that share a range will move the same layer.
Can I customize which stem drives which form?+
Yes. The stem-to-form mapping is fully configurable. You can assign any stem to any sculptural type, or disable individual stem visualizations entirely.
What if my song does not have vocals?+
The vocal-range layer will still respond to anything in that range, such as leads or guitars, so instrumental tracks keep all four forms moving.
