# SDK Report

## Python SDK

| Check | Status |
|-------|--------|
| Import | ✅ `from diarizen_sdk import DiarizenSegmenter` |
| Inference class | ✅ DiarizenSegmenter with NPU+CPU pipeline |
| Preprocessing | ✅ Audio resample + LayerNorm on CPU |
| Postprocessing | ✅ log_probs_to_probs, top_speakers_at_frame |
| Example | ✅ example.py with CLI and per-frame output |
| Requirements | ✅ numpy, onnxruntime, soundfile, pyaxengine |

## C++ SDK

| Check | Status |
|-------|--------|
| CMake configure | ✅ |
| Native build | ✅ libdiarizen_sdk.a + diarizen_example |
| Cross-compile | ⚠️ No aarch64 toolchain available (skipped) |
| Public API | ✅ DiarizenSegmenter class |
| Example | ✅ examples/main.cpp |

## Notes

- AX Engine runtime not available on dev machine; C++ SDK uses placeholder includes.
- CNN NPU inference requires pyaxengine / AX Engine runtime on target device.
- Backend ONNX runs on CPU via ONNX Runtime.
