Should fix the few cases where the PLC would create voice frames
that shouldn't be there.

Should handle the history in a more consistent way.
Slightly increase the model size and re-enable biased band loss in
training.

Code moved to compute_frame_features()

Starting with compute_linear()

Shift computation to concealment

And references to nnet_data.h

Remove old pitch estimator and retrain all models

Should make synthesis easier in the future

We're back to processing 10 ms at a time and have no need for 40-ms
"superframes".

Add arch to the LPCNet states, but right now it's always set to zero

Calls are deferred to the actual loss and we only process the minimum
required.

Can now inject FEC features to be used by the PLC when available

Jan Buethe authored 2 years ago and Jean-Marc Valin committed 2 years ago

Model now stores LPC gamma, look-ahead, and end-to-end.
Parameters aren't quite reliable yet, YMMV
