Nearfield binaural synthesis and ambisonics [PDF]
The Journal of the Acoustical Society of America, 2007 Ambisonic encodings can be rendered binaurally, as well as for speaker arrays. This process is developed for general high-order Ambisonic encodings of soundfields containing near as well as far sources. For sufficently near sources an error is identified, resulting from the limited field of validity of the freefield harmonic expansion.

Area, Volume 53, Issue 3, Page 492-500, September 2021., 2021 The last two decades have seen a “volumetric turn” within Anglophone social sciences and humanities scholarship. This turn is premised on the idea that space may be better understood in three‐dimensional terms – with complex heights and depths – rather than as a series of two‐dimensional areas or surfaces.

Journal of Contingencies and Crisis Management, Volume 29, Issue 1, Page 54-76, March 2021., 2021 Abstract The UK’s Initial Operational Response (IOR) decontamination protocol requires that chemically contaminated casualties remove contaminated clothing (disrobe) and then apply water or absorbent materials to skin. The health‐protective efficacy of the protocol is predicated on casualties quickly accepting both the need to act and the fact that ...

AmbiDrop: Array-Agnostic Speech Enhancement Using Ambisonics Encoding and Dropout-Based Learning [PDF]
IEEE International Conference on Acoustics, Speech, and Signal ProcessingMultichannel speech enhancement leverages spatial cues to improve intelligibility and quality, but most learning-based methods rely on specific microphone array geometry, unable to account for geometry changes.
