Externalization in data-based Binaural Synthesis: Effects of Impulse Response Length

نویسنده

  • Florian Völk
چکیده

Databases of head related impulse responses (HRIRs) for binaural synthesis can be measured either in anechoic or reflective environments. The time until energy decays to negligible values after impulsive excitation ranges from some milliseconds under anechoic conditions to some seconds in reflective environments. The computational load for dynamic binaural synthesis increases significantly with the impulse response length. For that reason short impulse responses would be preferable. If an authentic binaural simulation of an everyday listening situation is desired, an impulse response length in the order of the reverberation time or more would be necessary. A shortening of the impulse responses might lead to perceptual aberrations.

Segmentation and Analysis of Early Reflections from a Binaural Room Impulse Response

In this paper, a novel method for analysis of binaural room impulse responses is presented. Individual reflections are localized in time and frequency from a measured binaural room impulse response based on the continuous cross-wavelet transform (XWT). The directions of the reflections are then analyzed based on KEMAR and CIPIC reference data lookup, and compared a previous approach. Analysis o...

The role of spectral detail in the binaural transfer function on perceived externalization in a reverberant environment.

Individual binaural room impulse responses (BRIRs) were recorded at a distance of 1.5 m for azimuth angles of 0° and 50° in a reverberant room. Spectral details were reduced in either the direct or the reverberant part of the BRIRs by averaging the magnitude responses with band-pass filters. For various filter bandwidths, the modified BRIRs were convolved with broadband noise and listeners judg...

Individualization of dynamic binaural synthesis by real time manipulation of the ITD

Virtual acoustic environments (VAEs) are commonly realized via dynamic binaural synthesis. Therefore, anechoic audio is convolved in real time with head related impulse responses (HRIRs) or binaural room impulse responses (BRIRs). Binaural filters are exchanged inaudibly and in real time according to the listener’s head movements, thus providing a realistic auditory experience. From Lord Raylei...

Sound Field Synthesis Toolbox

An open source toolbox for Sound Field Synthesis (SFS) is introduced. The toolbox is able to numerically simulate sound fields synthesized by SFS methods like Wave Field Synthesis or higher order Ambisonics. Various loudspeaker driving signals for the mentioned methods are provided for 2-, 2.5and 3-dimensional synthesis. The toolbox allows mono-frequent as well as broadband excitation signals. ...
