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 โ€” or pick a video and let the app extract its audio track โ€” 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, pipes, 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 - A "Gacha Machine" loop mode where the ball travels through a capsule machine in a seamless loop - 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 - A "Props" panel for choosing which charms (star, heart, bell) and fixtures (bulb, torch, flower) may appear in a scene - A "Color" panel with several picture styles and an adjustable vignette - Automatic preset cycling that switches between saved presets at the interval you set - Multiple ball materials, trail effects, impact effects, extra effects, and wall textures - Adjustable lighting: brightness, color warmth, environment light direction, and environment light strength - Audio trimming so you can build a scene from just the section you want - Video export for saving the generated result to your device - A relatively lightweight installation footprint for a 3D scene creation workflow 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.

Then reorder by drag, or swipe a track straight to the top, the middle, a random spot, or the bottom, and map each of the four swipe slots to whichever action you use most. Add whole albums. Add what's playing. Clone a playlist and tidy up the copy. All of it tested on playlists of more than 17,000 tracks. A PLAYER WORTH LOOKING AT - Lyrics that scroll with the song, full screen, in four sizes. If they drift, tap the line you're actually hearing and they snap back into sync. The screen stays on while they're up. Pulled from your server, with an automatic LRCLIB fallback when it has none - Six visualizer styles that move to the track's own decoded audio once it has been analysed, and ambient motion until then - An optional waveform progress bar drawn from the song's own loudness - Colors pulled from the album art, and seven themes including true black - Star ratings saved straight back to Plex OFFLINE, PROPERLY Download a playlist and it keeps playing on your iPhone when the server is unreachable. Set a storage cap and Flex clears out whatever you play least, or turn on Keep favourites offline and it downloads your most-played tracks for you โ€” over Wi-Fi only, if you prefer. IN THE CAR CarPlay is included, free. Browse your playlists, albums and recent listening on the head unit, with artwork, and rate the playing track without touching your phone.
