EBU ADM Renderer (EAR) Documentation

The EBU ADM Renderer (EAR) is a complete interpretation of the Audio Definition Model (ADM) format, specified in Recommendation ITU-R BS.2076-1. ADM is the recommended format for all stages and use cases within the scope of programme productions of Next Generation Audio (NGA).

This documentation applies to the python reference implementation of the EAR, which can be found at https://github.com/ebu/ebu_adm_renderer.

This EAR is capable of rendering audio signals to all reproduction systems mentioned in “Advanced sound system for programme production (ITU-R BS.2051-1)”.

Further descriptions of the EAR algorithms and functionalities can be found in EBU Tech 3388.

From version 2.0, this is also the reference implementation of ITU-R BS.2127 (ITU ADM Renderer).
