PRISM

Audio visualizer & meter rack

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, it's a window into what you're hearing.

// SECTION_01 / ENGINE

Captures what you're hearing.

Prism pulls audio at the OS level, straight from CoreAudio on macOS, WASAPI on Windows, or PulseAudio on Linux. No virtual cables or routing hacks. Flip on device input mode when you want to analyze a mic or a line-in instead.

A native C++ analysis engine does the math. What you see is what you hear.

// SECTION_02 / PROFILES

.prsm

Your rack, saved and shared.

Save the whole rack as a profile. What's visible, how it's laid out, per-scope settings, popout window positions, all of it. Keep separate setups for mixing, listening, and streaming. Share them around like presets.

// SECTION_02 / THEMES

.iro

Every color, yours.

Spectrum gradients, oscilloscope traces, vectorscope bands. Every color lives in an editable theme file. Build one in a text editor, drop it into the Themes folder, or grab something from the community.

// SECTION_03 / STREAMERS

Chroma-ready out of the box.

Chroma key themes ship built in. Key the scopes out in OBS and drop them straight into your stream as transparent overlays. No masking, no compositing, no sweat.

// SECTION_04 / ECOSYSTEM

Runs next to Astra.

If you're already running Astra, Prism talks to it over the local API. The Now Playing scope pulls cover art, track info, and playback controls, and sets them next to your meters.

Prism works fine on its own, too. Astra's just a nice sidecar.

// Astra Integration

Now Playing scope
