Prerequisites

Needs parts of the FABIAN HRTF data base from (https://dx.doi.org/10.14279/depositonce-5718.3). Data can be loaded from demo.m.

Setup

Run demo.m (will temporarily add needed folders to the Matlab search path).

Running the sample

Run demo.m or execute block by block. Listen to audio files in Auralizations/ or use playAudio.pd.

Does brir.h contain direct sound?

Hello! I want to know if brir.h contains direct sound or it just contains early reflection and late reverberation.

I find its amplitude level is very low, so I'm wondering that should I add a unit-value delta at the beginning of the impulse response when I convolve it with my audio signal.

Thank you!
