Spatial and immersive audio has become increasingly mainstream, presented in concert halls and more recently through music streaming services. There is a diverse ecosystem of hardware and software controllers and renderers in both live and studio settings that would benefit from a standardized communication protocol. In 2019 a group of industry stakeholders began designing ADM-OSC to fill this need. ADM-OSC is a standard for transmitting metadata for object-based audio by implementing a namespace in parallel with the Audio Definition Model (ADM), a metadata standard developed in the broadcast industry. Open Sound Control (OSC) is a well-established data transport protocol developed for flexible and accurate communication of real-time performance data. By leveraging these open standards, we have created a lightweight specification that can be easily implemented in audio software, plugins, game engines, consoles, and controllers.
ADM-OSC has reached a level of maturity over multiple implementations be ready for an official 1.0 release. This paper will discuss the design of ADM-OSC 1.0 and how it was developed to facilitate interoperability for a range of stakeholders and use cases. The core address space for position data is described, as well as extensions for live control data. We conclude with an overview of future ADM-OSC development, including next steps in bringing together ideas and discussion from multiple industry partners.
