Computer networking technology has progressed to the point where off-the-shelf systems are becoming practical, cost-effective and adequately robust to employ in professional audio applications. Such systems allow replacement of traditional, “massively parallel” bespoke audio interconnection architectures with generic serial interfaces. This implies the replacement of dozens to hundreds of analog or AES3 pairs with a single – or at most a few – Ethernet connections. Applications range from point-to-point snakes and facility interconnections, to studio router systems, to fully IP-based multi-studio installations. A number of maSKIP PIZZI…nufacturers have developed systems implementing some form of “networked audio,” including a few that are implemented over standard IP networks, with proprietary elements added only at the application layer for latency mitigation.
To date, this technology has been broadly adopted in the broadcast industry, where thousands of installations already exist worldwide, and practically all new radio facilities being built or planned today will implement some form of networked audio infrastructure. The sound reinforcement and performance/presentation facility-design industry have also embraced the technology for audio transport and interconnection. It is expected that the audio recording and post industries will soon move toward networked audio systems, as well.
This presentation provides an overview of Networked Audio and AoIP, with emphasis on the technology’s practical applications and advantages for audio recording, production and presentation facilities
