Audio-related data often depends on spatial aspects. A very prominent example is the head-
related transfer function (HRTF), which describes the acoustic filtering of a sound source by …

Spatial decomposition method for room impulse responses

S Tervo, J Pätynen, A Kuusinen, T Lokki - Journal of the Audio Engineering …, 2013 - aes.org
This paper presents a spatial encoding method for room impulse responses. The method is
based on decomposing the spatial room impulse responses into a set of image-sources. The …

Room impulse response interpolation using a sparse spatio-temporal representation of the sound field

N Antonello, E De Sena, M Moonen… - … on Audio, Speech …, 2017 - ieeexplore.ieee.org
Room Impulse Responses (RIRs) are typically measured using a set of microphones and a
loudspeaker. When RIRs spanning a large volume are needed, many microphone …

Optimizations of the spatial decomposition method for binaural reproduction

SV Amengual Garí, JM Arend, PT Calamia… - Journal of the Audio …, 2021 - aes.org
The spatial decomposition method (SDM) can be used to parameterize and reproduce a
sound field based on measured multichannel room impulse responses (RIRs). In this paper …

Spatially oriented format for acoustics: A data exchange format representing head-related transfer functions

P Majdak, Y Iwaya, T Carpentier, R Nicol… - … Society Convention 134, 2013 - aes.org
Head-related transfer functions (HRTFs) describe the spatial filtering of the incoming sound.
So far available HRTFs are stored in various formats, making an exchange of HRTFs difficult …
