SOFA conventions

SOFA conventions specify the description of data and metadata for a particular kind of measured data.

This is important in order to meet the different requirements coming from different application fields, specified. For example, description of HRTFs, BRIRs, and DRIRs requires different metadata. Also, some applications may prefer to see the data stored in a different way. These conventions, once approved by the peer group are defined in SOFA conventions.

We consider following rules for new SOFA conventions:

• Data must exist (do not foresee the future)
• Data can not be described by existing SOFA conventions
• Relevant information about the data available

Stable Conventions

Stable SOFA conventions are those for which SOFA files are publicly available and can be read/modified by a software package. The following stable SOFA conventions are available now:

• SimpleFreeFieldHRIR: Free-field HRTFs stored as impulse responses, measured with an omnidirectional source for a single listener.

Proposed SOFA Conventions

Proposed SOFA conventions are currently being discussed. Measured data exist and the description must be fixed in order to create publicly available SOFA files and software.

• SimpleBRIR: Binaural room impulse responses measured with an omnidirectional source in a single reverberant space
• SingleRoomDRIR: Room impulse responses measured with an arbitrary number of receivers (such as a microphone array) and an omnidirectional source in a single room.
