You do not need a 3D editor or a hand-authored lighting timeline to experience a song as a virtual concert. Prismatic Arena handles the venue, fixtures, crowd and camera system, then derives its direction from the recording.
Choose the source
The bundled demo is the fastest test because it opens immediately. A local audio file is the most private option: it is decoded and analysed in the browser. A local video adds picture to the LED wall and IMAG screens. A supported YouTube URL is fetched through the self-hosted media bridge. Live microphone mode is designed for sources whose future is not known, such as an instrument, room or DJ set.
Use media you have the right to process and present. A visualizer changes the experience around a recording; it does not grant rights to the recording itself.
Let the analysis settle
Playback can start while the deeper analysis runs in a worker. At first, live audio features keep the arena moving. When the beat grid and structure are ready, the show locks to a more detailed timeline. A status message reports tempo and detected sections.
Tracks with clear drums usually produce the most obvious synchronization. Ambient, rubato or extremely dynamic recordings can still look compelling, but their pulse may be less explicit. The tap-tempo control can temporarily guide live timing when needed.
Shape the production, not the timing
Rig intensity changes how brightly the show runs. Glow affects beam width, haze and bloom. Graphics quality changes rendering cost. These controls alter the visual character while the beat and section cues remain aligned to the song.
Director camera mode is best for a hands-off performance. Free-look mode is useful when you want to frame a particular angle for a stream or recording. Stillness mode removes strobes and rapid movement without flattening the entire design.
Use fullscreen at the right moment
Load the source and confirm that analysis and playback are stable before entering fullscreen. For a stream, capture the browser at its native aspect ratio and keep the source audio on the same playback path. Avoid resizing the window repeatedly during a performance, since a WebGL renderer must rebuild parts of its output pipeline.
Give the song room
A virtual arena is most convincing when it has contrast. A verse should not look like a finale. Prismatic Arena intentionally holds back before major sections, allowing a chorus or drop to feel larger. Let the complete arrangement play before deciding that a quiet opening needs more intensity.
