The documentation on the Flexradio website is from 2016,

You wont attract too many FM people to 700D, LPCnet-C2 can win over
those , at least in terms of voice quality and robustness (compared to
DSTAR, and DMR is really more like CB) , given that LPCnet with a
relatively simple modem can be 12dB ahead of FM. Needs a frequency
hopping radio
Hi Adrian
Good rational points you make.
BTW:AD9361, AD9371, ADRV9008 are all "sub-optimal" (I have to be nice to
my ADI friends) for narrow band work.
too noisy, insufficient dynamic range.
But this new one is worth looking at (I have info on it on NDA)
here is the (public) pre release
Free software is not popular at all among end users and it will probably never
be as popular as closed software.
Instead, free software is incredibly popular and successful for enterprise
users and companies. Right now, from the largest 8 software companies in the
world, only one does not

LPC net can work on a Pi etc
the GRU functions need splitting into 4 threads (if four cores)
So that NEON is utilized on the four cores. then, no problem.
Some thought needs to be put into array access order to minimise cache
misses, which I suspect hurts ALOT.

Hi all,
Am I right?
Mode 2020 needs a lot of CPU power eg. AVX/AVX2 to work.
All the other codecs and modems (modes) run well on the
STM32 series and almost any Pi or clone.
So, can our experts explain the real usefulness of LPCnet?
Would we do better thinking on compressing, say the 700D
