Dear All, I would like to add a few words to the discussion on the AES69-2015 / SOFA format:
AES69 standardizes the SOFA file format to exchange space-related acoustic data. The format is designed to be sufficiently flexible to include source materials from different databases and for different use cases (e.g., HRIRs, MIMO-RIRs, etc.). AES69 is split in two parts: (1) the main body of the text, wich defines dimensions and general rules for creating so-called conventions; (2) ‘conventions' for a consistent description of particular setups in the annex. A ‘convention’ defines recommendations on the naming of AES69 attributes, variables, and dimensions for particular application fields. In other standards a set of ‘conventions’ is often referred to as a ‘profile’. Conventions are discussed on the SOFA website (http://www.sofaconventions.org/). As soon as a new convention is considered as being consistent and stable, it will be added to the annex of the AES69 standard through the normal revision process. In other words, if you want AES69 / SOFA to support ATK, feel free to open the discussion on a new set of conventions. Open source APIs for Matlab, Octave, and C++ are available at http://sourceforge.net/projects/sofacoustics/. The API provides functionality to create, read, and write AES69 ‘.sofa’ files. You can freely download and use the APIs, in whole or in part, for personal or commercial purposes.
