⚫	This conventions was developed for binaural room impulse responses (BRIRs) measured in a multispeaker setup (=multiple emitters). It is based on SimpleFreeFieldHRIR with the most striking difference of using the '''FIRE''' as DataType. This allows to more compactly describe the data for all involved emitters.

MultiSpeakerBRIR added

New page

==Description==

This conventions was developed for binaural room impulse responses (BRIRs) measured in a multispeaker setup (=multiple emitters). It is based on SimpleFreeFieldHRIR with the most striking difference of using the '''FIRE''' as DataType. This allows to more compactly describe the data for all involved emitters.

== Version 0.2 ==

In this version, we explicitly use the Datatype FIRE.

Also, the size of E is defined by the size Data, which is consistent with other SOFA conventions.

== Old, deprecated versions ==

=== Version 0.1 ===

This was the first version, it used FIR datatype which was inofficially extended by E. Also, the comment said that EmitterPosition determines the size of E, which is deprecated as well.
