Software tools for object-based audio production using the Audio Definition Model (ITU-R Recommendation BS.2076)

We present a publicly available set of tools for the integration of the Audio Definition Model (ADM) in production workflows. ADM is an open metadata model for the description of channel-, scene-, and object-based media within a Broadcast Wave Format (BWF) container. The software tools were developed within the European research project ORPHEUS (https://orpheus-audio.eu) that aims at developing new end-to-end object-based media chains for broadcast. They allow for recording uncompressed multichannel audio files with embedded XML metadata according to the ADM specifications, and monitoring and rendering existing BWF-ADM files over headphones or arbitrary loudspeaker setups. The bundle also includes a plugin (supporting all major formats) for interoperability with digital audio workstations, which provides support for time-varying metadata via automation tracks.
