[Allstar Digital] hb_ambe_audio

[Steve Zingman]

Maybe I'll backup a little.

DMRlink and HBlink were created by Cort, N0MJS. DMRlink as a package 
will allow you to do quite a few things you might want without having to 
connect to a larger network. DMRlink is built for IPSC networks. (Think 
Motorola) A Motorola repeater uses IPSC to communicate with other 
Motorola repeaters. Motorola repeaters can also communicate with larger 
networks built with systems like c-Bridge or BrandMeister. DMRlink 
allows us to build networks without c-bridges or BM. A DMRlink network 
can communicate with other larger networks, but it does not have to. 
DMRlink includes a number of "applications" that run on top of the main 
DMRlink.py program. Some of those applications include bridging, parrot, 
record and playback. ambe_audio was a example skeleton program, it did 
not really do anything. Mike N4IRR used the skeleton to build a 
application that would accept data (AMBE) from DMRlink and send it to 
DMRGateway. DMRGateway formats that AMBE and sends it to the DV3000. The 
DV3000 returns analog (PCM) which DMRGateway sends to AllStarLink. This 
same PCM can be sent to and from other devices like a microphone and a 
speaker.

HBlink is built for HB Protocol. (Think MMDVM) a MMDVM base repeater or 
hotspot uses HB Protocol to communicate with BM. HBlink allows us to 
build networks without BM. Just like DMRlink, HBlink as applications 
built for it.  Some of those applications include bridging and parrot. 
hb_ambe_audio does what ambe_audio does for DMRlink. hb_ambe_audio 
accepts data (AMBE) from HBlink and send it to DMRGateway. DMRGateway 
formats that AMBE and sends it to the DV3000. The DV3000 returns analog 
(PCM) which DMRGateway sends to AllStarLink. This same PCM can be sent 
to and from other devices like a microphone and a speaker.

As of today, HBlink can communicate with MMDVM, BM and I think OpenSpot 
(don't quote me). DMRlink can communicate with Motorola repeaters 
c-Bridges and BM. Neither DMRlink or HBlink can communicate with Hytera 
repeater or each other. DMRlink can NOT communicate with HBlink (today)

DMRlink and HBlink are NOT meant to replace larger networks, the give 
YOU control of your network! Oh, and did I mention they are OPEN SOURCE?
