Braxton Boren studied Music Technology at Northwestern University, working with spatial sound and 3D audio as well as interactions between video games and music. In 2009, he came to the University of Cambridge to simulate the acoustics of Renaissance Venetian churches. Braxton is currently a doctoral student in Music Technology in New York University's Music and Audio Research Lab as part of the 3D Audio research group. |

Multichannel Impulse Response Measurement in Matlab
This paper describes ScanIR, an application for flexible multichannel impulse response measurement in Matlab intended for public distribution. The application interfaces with the PortAudio API using Psychtoolbox-3, a toolkit in Matlab allowing high-precision control of a multichannel audio interface. ScanIR contains single-channel, binaural, and multichannel input modes, and it also allows the use of multiple output test signals. It is hoped that this application will prove useful to researchers using Matlab for physical or psychological acoustic measurements.
The Effects of Headphones on Listener HRTF Preference
Listener-selected HRTFs have the potential to provide the accuracy of an individualized HRTF without the time and resources required for HRTF measurements. This study tests listeners’ HRTF preference for three different sets of headphones. HRTF datasets heard over the noise-cancelling Bose Aviation headset were selected as having good externalization more often than those heard over Sennheiser HD650 open headphones or Sony MDR-7506 closed headphones. It is thought that the Bose headset’s frequency response is responsible for its superior externalization. This suggests that in systems where high quality headphones are not available, post-processing equalization should be applied to account for the effect of the headphones on HRTF reproduction.
