AN ACOUSTIC FINGERPRINT ?

As an addendum to my post from three weeks ago, concerning my newly published book on SPRINGER Nature "THE ART AND SCIENCE OF SURROUND AND STEREO RECORDING" I wanted to let you have a look into what it is - partly - about, by putting a video on YOUTUBE, which deals with the - perceptually crucial - question of signal correlation in (stereo) main microphone systems. 

For realising this video I have used MAAT.digital's brilliant "2BCmultiCORR" plugIn, which displays the FCC (Frequency dependent signal Cross-correlation Coefficient) in realtime. Due to the abundance of my comments ;) I actually had to split the video (which shows the FCC for AB, XY, ORTF, MS, NOS, KFM and Jeckling-Disk mic techniques) into two parts, as YOUTUBE allows explanatory texts of only up to 5000 characters per video. 

The nice thing about the FCC-analysis is that it visually unveils characteristics that are typical for each technique, which is why I compare this approach to taking something like an 'acoustic fingerprint'. The results of the corresponding MATLAB-FCC graphic figures - as presented in various chapters of my book - may even be visually clearer in this respect, but the realtime-FCC on the other hand has the charm of offering the possibility to simultaneously listening to what happens acoustically (withing the music and room) along the recorded excerpts ...

For those who want to get some more info about the content of the book, you can easly download a PDF of the "Frontmatter" (Preface, Table of Contents, Abbreviations) as well as the "Backmatter" (Index and Appendix, which also includes my MATLAB-code for non-realtime calculation of the FCC) of the book, when you access it via SpringerLink (soft-button far down on my book-info webpage on SPRINGER.com). Also, Amazon.de has been so generous as to let interested readers have a "Look inside", which enables you to actually access large parts of the first chapter which is dedicated to "SPATIAL HEARING", and offers a good basis for better understandig (and working in) 3D audio. 

Here is the link to the first of the above-mentioned videos on Youtube, as part of the "MIC TECH ANALYSIS" video series:
