Prism

Prism taps into your system audio and runs it through a rack of real-time scopes and meters. Whether you're mixing a track, tuning a room, or just like watching your music, Prism gives you a window into what you're hearing.

It captures straight from your system audio at the OS level (CoreAudio, WASAPI, or PulseAudio) with a capture-to-display latency under 8ms.

Scopes

Seven visualizers, each independently configurable:

• Spectrum Analyzer — FFT frequency display with heatmap and fill modes, configurable FFT size, spectral tilt, and log or linear scaling
• Oscilloscope — Time-domain waveform with pitch-lock mode that syncs to the fundamental frequency
• Vectorscope — Stereo phase visualization with five display modes and optional multiband RGB split
• Spectrogram — Scrolling frequency-over-time display with mel, log, and linear scale modes
• VU Meter — Classic loudness metering in needle or bar style, horizontal or vertical
• Loudness Meter — LUFS metering following ITU-R BS.1770 with fast stereo peak activity
• Waveform — Scrolling time-domain view with mono, stereo, and multiband modes

Drag and resize scopes into any layout. Pop any scope into its own window and pin it on top so it stays visible while you work.

For Streamers

Prism ships with chroma key–friendly themes out of the box. Key out your scopes in OBS and drop them straight into your stream as transparent overlays.

Profiles & Themes

Save your entire rack layout, scope visibility, positioning, per-scope settings, and popout windows, as a .prsm profile. Keep separate setups for different workflows and share them with others.

Themes are fully customizable through editable .iro files. Build your own or grab one from the community Discord.

Astra Integration

Already using Astra? Prism can connect to its local API to pull in now-playing info, cover art, and playback controls alongside your scopes. It can also connect to Spotify on Windows and Macos, with Tidal planned in the future.
