BeatDance

BeatDance is an original creation tool for turning your own audio into beat-synced 3D music ball videos. Import an MP3, M4A or MIDI file from your device — or pick a video and let the app extract its audio track — and the app analyzes the rhythm and automatically builds a 3D scene in seconds. During preview, the ball bounces, rolls, and interacts with generated structures such as boards, rails, and bells exactly on the beat, so the motion and the music stay visually locked together. Before generating, you can pick the part of the song you want: drag the two handles on the waveform to select a section, or use auto-trim to remove the silence at the start and end. The 3D scene and the exported video use only that section. Unlike tools that require manual 3D editing, BeatDance focuses on fast automatic scene generation. After importing audio, users can directly get a playable scene without placing platforms or adjusting timing by hand. BeatDance also includes features designed for visually distinctive results: - Seamless loop playback and export, with loop-aware scene construction for continuous replay - Curved World styles that bend the whole scene for a more unique visual look - A first-person view that places you inside the scene for a more immersive way to watch the ball - Multiple ball materials, trail effects, impact effects, wall textures, lighting environments, and other visual options - Audio trimming so you can build a scene from just the section you want - A relatively lightweight installation footprint for a 3D scene creation workflow - Video export for saving the generated result to your device BeatDance is built for creators who want to quickly turn music into stylized 3D rhythm visuals on mobile. Disclaimer: This app provides audio analysis, scene generation, preview, and export tools only. Please make sure you have the legal right to use any audio or video files you import.
