Probably you can find one that fits your necessities.=20 -P. Coleman and colleagues from Surrey University have been working on the field for a while. Within their S3A project, they gathered ambisonics RIRs from 5 different enclosures [3]. You can download the data from here [4] (upon registration). -The Center for Digital Music at QMUL provides ambisonic IR recordings [1] from 4 different rooms. (These are the datastes from isophonics that you comment). -The Open Acoustic Impulse Response Library (OpenAIR [5]) from York University features ambisonics IR recordings from around 15 different rooms. -Adavanne and colleagues from Tampere University have recently released a dataset of reverberant ambisonics recordings [6] (along with the synthetic IR version [7]) for SED.=20 While the actual IRs are currently not available, I would say it is possible to contact the authors for that issue. - My colleague J. de Muynke has just released a collection of ambisonic IRs gathered within the BINCI project [8]. It consists of 23 sets of recordings at three different european touristic sites, using three different microphones (including an Eigenmike). The files are stored in the recently proposed AmbisonicsDRIR SOFA convention [9], and can be used with the Matlab [10], C++ [11] and Python [12] APIs. Given the growing interest on these kind of datasets, I hope that we can centralise the information in the next future. Personally, I would bet for the OpenAIR lib...
