EchoSphere

EchoSphere is a mobile + desktop app that lets indie musicians, podcasters, and XR creators produce convincing spatial audio mixes without owning expensive studio gear. You import stems, pick a target format (Apple Spatial Audio, YouTube 360, Meta Quest), then place sound sources in a simple 3D scene. The app previews in real time with head tracking on supported headphones/VR headsets, and exports deliverables with correct metadata and loudness targets. It also includes a “room capture” mode: record a short impulse response in a real room (phone mic + speaker sweep) to approximate that room’s reverb for immersive mixes. This is a combination traditional + AI app: AI helps auto-place sources, reduce phase issues, and suggest binaural settings, but the core is deterministic audio rendering so results are predictable and shippable.
