Spectra Play is a modern music player with GPU-accelerated visuals. Point it at your own audio and watch it come alive with a choice of nine real-time visualizers rendered in WebGL2.
How it works. You pick a folder of music and the app lists everything inside it — loading a whole directory at once and remembering it for next time. As a track plays through the audio engine, the app continuously analyses the sound, splitting it into a live frequency spectrum (how much bass, mid and treble there is right now) and a waveform (the raw shape of the sound). Those two streams of data feed the visualizers: ribbons, bars, orbits, particle fields and nebulae that are rebuilt every frame and coloured by a shader, so the graphics pulse and flow in perfect time with the music. Track titles and artists are read straight out of the files' own tags.
How you interact:
- Load a folder — choose a directory of music to build your library; click any row to play it.
- Playback controls — play/pause, previous/next, a seek bar and volume, plus shuffle and a repeat mode (off, all, or one).
- Switch visualizers — step through the nine animated scenes with the arrows.
- Keyboard shortcuts — space to play/pause, arrows to seek, and N / P to skip tracks.
Plays common formats including MP3, FLAC, AAC, WAV, OGG and Opus, and runs entirely on-device.
