# 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, depth, and fusion;
|
|
- Fensalir D3D12 compute/render paths;
|
|
- Faust/native DSP;
|
|
- OBS-facing program outputs.
|
|
|
|
Visual/GPU research entry points:
|
|
|
|
- [[d3d12-stereo-depth-provenance-2026-05-29|D3D12 Stereo Depth Provenance]]:
|
|
libSGM is the current permissive north-star reference for a future
|
|
Fensalir-owned D3D12 compute stereo-disparity lane. External CUDA/TensorRT
|
|
projects are provenance only, not runtime authority.
|
|
|
|
Audio timing research entry points:
|
|
|
|
- [[chirplet-sync-decoder/summary|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|Live Adaptive Sync Summary]]: passive
|
|
program-audio synchronization and
|
|
sample-rate-offset estimation.
|
|
- [[feedback-calibration/summary|Feedback Calibration Summary]]: online
|
|
room/speaker/mic response
|
|
calibration.
|
|
- [[ambisonic-aquasynth/summary|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.
