A hybrid loudspeaker system consisting of dynamic point sources and parametric loudspeaker models shows great results above, generally inevitable, soundfield aliasing frequencies.
This work was presented at APSIPA ASC 2016 in Jeju, Korea.
Recent work on perceptual soundfield reproduction for multizone soundfield cases was presented in Hong Kong at the Asia-Pacific Signal & Information Processing Association Annual Summit and Conference (APSIPA ASC).
After having spent a good while looking for a working copy of the Perceptual Evaluation of Speech Quality measure implemented in MATLAB, I ended up using the readily available “wrapper” functions found on the MATLAB file exchange site. While these wrappers work a treat they are a bit slow as they require a call to the system to run the PESQ binary file. The PESQ binary file is compiled from the source code found on the ITU site for the PESQ standard. The source code is written in C which MATLAB supports for its MATLAB executable (MEX) compilations. That was what then prompt me to look for a MEX compiled version of the PESQ measure but to my surprise I couldn’t find any. I managed to get the ITU standards’ source code compiled and working in a MEX function and I will go through the few steps required to do it.
