19 granted US patents and 7 published applications in spatial audio, streaming, media, and device telemetry, all assigned to Microsoft.
Estimates the user experience on devices that send no detailed telemetry by matching each one to the most similar device that does.
Decides which incoming sounds, such as game effects, chat, or music, should be spatialized and which should play as they are.
Checks a user’s license for premium audio rendering software, so cloud-streamed apps can render their audio with it on the server.
Tunes the audio of cloud-streamed apps on the server to match the player’s own device and audio settings.
Switches spatial audio technology automatically as the setup changes, such as moving from Dolby Atmos to HRTF when headphones are plugged in.
Carries spatial audio and its position metadata together in the same codec frames, with no separate metadata channel.
Sends game spectators a shared audio mix that each viewer’s device then personalizes for their own ears.
Lets several apps share one 3D layout of virtual speakers, rendered with whichever spatial audio technology is active.
Picks the best spatial audio technology for the connected speakers or headphones and the listener’s preferences, across every app.
Automatically creates replay clips of key moments in VR sessions, with cloud-rendered spatial audio that matches each camera angle.
Gives apps an interface to share a limited budget of spatial sound objects, rendered for whatever output device is connected.
Renders personalized 3D audio in the cloud and streams it to devices that can’t do the processing themselves.
Streams game audio as a speaker-independent sound field, so any remote device can render it spatially.
Shares limited spatial audio resources fairly between apps by having each declare the minimum it needs to work.
Lets a phone hand a TV or speaker a link to cloud media, which then streams it directly while the phone sleeps.
Infers how well an operating system performs on devices without detailed telemetry from the most similar devices that have it.
Chooses which spatial audio encoder to stream with based on bandwidth and the listener’s device, switching as conditions change.
Lets VR spectators look around freely from a player’s position, with spatial audio that follows where they look.
Shows media cast to a PC with operating system controls, so it behaves like any other app window.
Lets a locked device show content projected from another device, and control it, without being unlocked.
Lets an app send its own audio to a chosen device, such as a Bluetooth speaker, while system sounds play elsewhere.
Finds media playing on other devices, like a TV or game console, and controls it with your phone’s own interface.

Hi. I know Steven's roles, results, patents, recommendations and what he is looking for. Ask me anything, or paste a job description and I'll say what his record covers, what it doesn't, and what to ask him. Your own AI assistant can read the same record through steven.wilssens.com/mcp.
