hello
m17 looks like an embedded project that will not be able to use the last
AI powered but resource hungry modes, because they only use a STM32 in
their handheld.
Moreover their goal does not look like to reduce the used bandwidth or
work HF DX, but to provide clear audio that competes with proprietary
solutions on VHF and UHF.
So is it really bad if they only use the the old but lightweight modes?
For me at least it makes a lot of sense.

Hi,
Adapting "dudestar" to use the latest Codec2 library is proving
difficult for me, a "hacker" at best.
I'd really like to do this as I'd be unhappy with the M17 project
being limited to only the Codec2 modes 3200 and 1600.
C++ "Scope" problems.

Hi guys,
The "dudestar" app https://github.com/nostar/dudestar
Makes use of the 3200 mode from 2010 to be compatible with the M17
project.
Can the "dudestar" software in the "Voice & Data" mode be changed to
use the lower bit-rate modes such as 700 or even 450?
To keep the internet packet format the same, in this V&D mode just
have more "space" for data.
As it stands, in the "Type" field bits, there is provision for encryption.
It's been commented that "encryption" should be OUT. This frees up
the bits for more vocoder types.
Will an app such as this and "DROIDstar" encourage "over the
internet" experimentation with alternate vocoders?
BTW: The 3200 mode sounds quite good as long as one's mic audio level
is adjusted down below clipping. (Use the O/S volume control app)
(and the background noise level is low) (lessons from my laptop
internal mic that "hears" the CPU fan very well)
