Hi Jeroen,
LPCNet is designed for 16 kHz audio, and expects the full bandwidth to
be present at the input, e.g. like a signal sampled from a headset.
There are some suitable samples in the LPCNet/all directory.
If you are running 8kHz sampled speech though it, yes I'd expect the
pitch estimator
I added a bit-scrambler to the modulator to see what it would do. Haven't
figured out how to add it to the demodulator yet though.

Hi,
I've just loaded a Raspberry Pi 4B with the latest HamVOIP.
RPi2-3-4 Version 1.6-09 Allstar - March 01, 2020 - KB4FXC, WA3DSP
and downloaded the codec2-dev library and compiled it.
My thoughts were to complete a Tait T800 VHF repeater system I have here
and it having a RPi4B, it should be
Sounds pretty impressive Jeroen.
Well done..

Hi David,
I got LPCNet running at several different rates. I am not yet using it
on the air though as the controller in our local repeater is an ARM
system with not enough power to handle LPCNet (it is an dual core
cortex-A7).
I also found that in its current form it isn't very good at coding
