After the ICSA2011, we conducted impulse response measurements with our KEMAR manikin in the Wave-Field-Synthesis-Studio of ETI.
Binaural Room Impulse Responses (BRIRs) were measured for each of the 80 loudspeakers of the WFS array. By means of a step motor built into the manikin each measurement was done for head rotations ranging from -80 to 80 degrees in 2-degree steps.
The data allow for the binaural resynthesis of the loudspeaker array or a subset of the loudspeakers, to be used, for example, in listening tests.
Post-processing is not yet finished (all data will be available here ASAP), but here is a sneak peek:
This is a small part of the data, containing only head angles of 0 degree (straight ahead), but all 80 loudspeakers.
The description of the file format can be found here: IRs File Format.
Each column in the fields
.right corresponds to a loudspeaker.
The IRs are not headphone-compensated, it is highly recommended to apply one of the headphone compensation filters available here:
- AKG K271 - closed: source:compensation/QU_KEMAR_AKGK271_hcomp.wav
- AKG K601 - open: source:compensation/QU_KEMAR_AKGK601_hcomp.wav
- Sennheiser HD25 - closed: source:compensation/QU_KEMAR_SennheiserHD25_hcomp.wav
Even if you use different headphones, choose one of the three compensation filters, because the wrong compensation is normally much better than no compensation at all!
