Research Archive
This directory preserves implementation research and hard-won calibration lessons. It is allowed to mention external tools, papers, vendor docs, and failed paths because forgetting those days would be an expensive little act of self-sabotage.
Research is not runtime authority.
Use it to shape native implementation decisions:
- direct camera and audio drivers;
- pinned/native buffers;
- GPU feature extraction, flow, matching, and fusion;
- Fensalir D3D12 compute/render paths;
- Faust/native DSP;
- OBS-facing program outputs.
Audio timing research entry points:
- Chirplet Sync Decoder Summary: chirplet transform notes, why dense matched-filter search was cut from the hybrid hot path, and the current dechirp plus FFT/Goertzel decoder shape.
- Live Adaptive Sync Summary: passive program-audio synchronization and sample-rate-offset estimation.
- Feedback Calibration Summary: online room/speaker/mic response calibration.
- Ambisonic AquaSynth Summary: spatial audio and Ambisonic reference material; useful background, not a license to call unsynchronized mics a coherent field.
Do not promote mirrored examples, old probes, or external library demos into the Mimir hot path just because they exist here. If research points at a concept, rebuild the live version in the Mimir/Fensalir/native stack with a clear owner and invariant.
