AB  - We present a novel pipeline to estimate reverberant spatial audio object (RSAO) parameters given room impulse responses (RIRs) recorded by ad-hoc microphone arrangements. The proposed pipeline performs three tasks: direct-to-reverberant-ratio (DRR) estimation; microphone localization; RSAO parametrization. RIRs recorded at Bridgewater Hall by microphones arranged for a BBC Philharmonic Orchestra performance were parametrized. Objective measures of the rendered RSAO reverberation characteristics were evaluated and compared with reverberation recorded by a Soundfield microphone. Alongside informal listening tests, the results confirmed that the rendered RSAO gave a plausible reproduction of the hall, comparable to the measured response. The objectification of the reverb from in-situ RIR measurements unlocks customization and personalization of the experience for different audio systems, user preferences, and playback environments.
