This repository contains a set of tools to render Binaural Room Impulse Responses (BRIR) using the Spatial Decomposition Method (SDM).The implementation features a series of improvements presented in Amengual et al. 2020, such as quantization of the direction of arrival (DOA) estimates to improve the spectral properties of the rendered BRIRs, or RTMod and RTMod+AP equalization for the late reverberation.The repository also contains the necessary files to 3D print an array holder of optimized topology for the estimation of DOA information.

Incorporated new equalization options to make reverb eq process more robust. #1
BRIR_data.BandsPerOctave: Specifies the frequency resolution for the
reverb equalization. The values can be 1 or 3. For smaller rooms, 1 is
recommended. By default it is 3.
BRIR_data.EqTxx: To perform reverb equalization, the RT60 must be
estimated. However, there is generally not enough SNR to obtain a true
T60 estimation. This parameter allows the user to specify the desired
Txx for the RT60 estimation. Generally, a value of 30 is recommended.
However, this can blow up the RT estimation in cases where SNR is low.
For small rooms and very dry spaces we recommend using a value of 20. By
default it is 30.
Updated the demo script to showcase usage.
Now user can specify two new fields in BRIR_data:
