The simulation of distance in multi-channel audio

This project was to carry out the necessary research to firstly ascertain what it is the SoundField mics are recording in order to encode distance. This was tested using our SoundField microphones in combination with the software packages Adobe Audition 3 and the Aurora audio testing plug-in suite. The results can then be used to create a plug-in for standard audio packages (a VST plug-in) to correctly encode distance cues with the panning information. The work will also feed into SPARG's previous research as it can also be used in the calibration of the Ambisonic decoders that have already been created by as distance compensation can then be setup to take into account a) what distance the SoundField mics
were calibrated at (i.e. where their 'focal distance' is set to) and b) the distance at which the speakers are. This work was presented at Institute of Acoustics' Reproduced Sound 25 International Conference and the University of Derby's annual research conference (2009).
