Audio analysis preview

Waiting for audio upload…

Upload an audio file to preview its waveform, complete with second markers and a consistent time scale.

Only sounds louder than this value trigger marble events. Lower it for more activity, raise it for precise hits.
5.0
Controls how closely detected peaks are merged. Short windows keep rapid hits separate; longer windows blend nearby beats together.
0.075 s
Defines how long a segment must be to spawn a ramp. Lower it to allow shorter ramps throughout the track.
1.00 s
Skip up to five seconds before analysing the song. The trimmed lead-in appears as a red hatched overlay on the waveform preview.
0.00 s
Ignore up to five seconds at the end of the track to avoid long fade-outs. The trimmed ending is highlighted in red on the waveform preview.
0.00 s

Launch & motion

Set how marbles start moving and how they react to the beat.

Drag the arrow to set horizontal (X) and vertical (Y) launch speeds. Fine-tune the values directly if you need precise numbers.
Magnitude 335

Fine-tune the motion

Control how the marbles move, bounce, and interact with the music.

Scales the whole simulation in time. Use slower values for cinematic motion or higher values for tighter pacing.
Strength of the downward force applied every frame. Higher gravity accelerates drops and increases impact energy.
Multiplier applied to marble elasticity. Raise it for livelier rebounds or lower it to dampen motion.
Upper limit for marble speed. Lower caps keep motion controlled, while higher values allow explosive bursts.
