Audio over IP (AoIP) has been used in broadcast facilities for about 20 years now. A few broadcast facilities have swapped one brand or standard of AoIP equipment for another during that period. Some broadcasters have swapped equipment twice! Whether the reasons for changing equipment are technical, political, old age, or support issues, we’d like to know about the challenges - or the easy aspects - of changing AoIP brands and standards. Matt Levin is a broadcast engineer in Ohio. His consulting and studio construction work take him to different facilities to make upgrades. Chris Tarr and Kirk Harnack discuss with Matt about using different AoIP systems, using console profiles effectively, and about FM audio processing running on PCs and servers.
