Recent work on a reverberant spatial audio object (RSAO) encoded spatial room impulse responses
(RIRs) as object-based metadata which can be synthesized in an object-based renderer. Encoding
reverberation into metadata presents new opportunities for end users to interact with and personalize
reverberant content. The RSAO models an RIR as a set of early re
ections together with a late
reverberation filter. Previous work to encode the RSAO parameters was based on recordings made
with a dense array of omnidirectional microphones. This paper describes RSAO parameterization from
first-order Ambisonic (B-Format) RIRs, making the RSAO compatible with existing spatial reverb
libraries. The object-based implementation achieves reverberation time, early decay time, clarity and
interaural cross-correlation similar to direct Ambisonic rendering of 13 test RIRs.
