Hi David,
Interesting post. Just curious, did you manage to understand why the LPC
model doesn't really fit the amplitudes you're trying to represent? And
most importantly, have you considered modifying the encoder-side LPC
model instead of compensating on the decoder side? It seems like it
would be more "future-proof" that way. That would be a bit like the SILK
part of Opus applying its pre-filter rather than a post-filter.
Cheers,
Jean-Marc
