DTLN-aec 256 (CoreML)
Stateful CoreML conversion of the 256-unit DTLN-aec acoustic echo canceller, for on-device real-time echo cancellation in Narrato on Apple Silicon (macOS 14.4+).
- Source model: breizhn/DTLN-aec
(
dtln_aec_256_{1,2}.tflite), MIT licensed. Original work © Nils L. Westhausen. - Conversion:
tflite → onnx → torch → CoreML(see Narrato'sscripts/convert_dtln_aec_coreml.py). Validated faithful to the original TFLite (RMS ~4e-4 through the full run_aec framing).

16 kHz mono. Two stages with an explicit LSTM state tensor carried frame-to-frame.
