Murmur Cast Overview

MURMUR CAST captures a live multitrack performance, spatializes it into a bed-plus-moving-objects mix, and delivers a rendered version to remote listeners — never the raw discrete tracks — matched to whatever system they’re on: binaural over headphones, or a full speaker-bed render over a home theater rig.

Murmur Cast started as a subdirectory inside murmur-app and became its own repository once it outgrew that — it still reuses murmur-app’s binaural panner and DSP primitives via a pinned dependency. See murmur-cast on GitHub for the full architecture.

The DAW-side tap

A small plugin still lives in murmur-app (cast_plugin/) — a two- parameter tap that sits inline in your DAW session and writes a copy of the mix to a shared buffer for the separate Cast process to pick up, without touching the audio you’re mixing. See Murmur Cast parameters for both real parameters (Stream Gain, Casting).
