Convention Paper

A Binaural Model to Estimate Room Impulse Responses from Running Signals and Recordings

Authors: Braasch, Jonas; Dahlbom, David; Keil, Nate

AES Convention 147 · Paper 10257 · October 2019

Abstract

A binaural model is described that can use a multichannel signal to robustly localize a sound source in the presence of multiple reflections. The model also estimates a room impulse response from a running multichannel signal, e.g., from a recording, and determines the spatial locations and delays of early reflections, without any prior or additional knowledge of the source. A dual-layer cross-correlation/autocorrelation algorithm is used to determine the interaural time difference (ITD) of the direct sound source component and to estimate a binaural activity pattern. The model is able to accurately localize broadband signals in the presence of real room reflections.
