Summary
Benchmarks
Measured inference time on Raspberry Pi using 500 iterations of model.predict() on a single 80ms audio chunk (1280 samples, 16kHz mono int16):
onnx: mean 5.02ms, max 5.71ms
tflite: mean 4.07ms, max 4.71ms (~19% faster on ARM)
Testing
-Added unit tests
-manually tested onnx and tflite on mac and linux
