I thought that reverse enginering ambe would be illigal... "however ICOM DSTAR radio users wouldn't hear a lick of difference - it's all translated to and from AMBE anyways..."
I do not think ambe would like this. The fact that an open source codec is out there, free, that does what their codec does, and is compatible WITH their product (read: their product can be swapped with something they can't profit from in any device that currently has an ambe chip) could potentially cost them a lot of money. I hope for you that they don't have a patent or any other legal leg to come after you if you ever finish this.. 73s Robbie ON4SAX On Mon, Jun 7, 2010 at 8:59 PM, John Hays <[email protected]> wrote: > > > > On Jun 7, 2010, at 9:50 AM, a cutler22 wrote: > > > I miss-read this tidbit - > > Protocol forks are everpossible, and once the door for codec > experimentation. *However*, the one advantage Codec2 would have any other > competing protocol is time - it's the first on the scene and it's not like > writing an competitive-to-AMBE codec is child's play - its damn hard! > > Plus, competition in the DSTAR protocol field would invigorate increased > innovation among protocols, a "marketplace" would develop and the best > protocol would prevail. > > With dual (or tri or quad etc) codec repeaters, any and all Codec2 > offshoots would be implementable, however ICOM DSTAR radio users wouldn't > hear a lick of difference - it's all translated to and from AMBE anyways... > > -73, KE7HQY > > > Ummm -- you don't think profit driven code/vocoder development isn't > pushing for innovation?
