Subject: Huggins pitch with speech? From: =?ISO-8859-15?Q?Michael_Buscherm=F6hle?= <=?ISO-8859-15?Q?Michael_Buscherm=F6hle?=> Date: Fri, 28 Sep 2012 14:31:03 +0200 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>Dear list, I just recently stumbled upon the following book chapter by Manfred Schroeder: http://books.google.de/books?id=cg7x5_-vB-AC&pg=PA190&lpg=PA190&dq=manfred+schr%C3%B6der+huggins+pitch&source=bl&ots=tjbeher3kK&sig=TDtA5RUN1VLztWX55rKwKy-Hy_Q&hl=de&sa=X&ei=n1xkUOXhDsPOtAaeo4CoBw&ved=0CDEQ6AEwAA#v=onepage&q=manfred%20schr%C3%B6der%20huggins%20pitch&f=false In that chapter (Chapter 10.6) he explains that an effect similar to the Huggins pitch can also be evoked with speech (i.e. you have two unintelligible mono noise signals that reveal intelligible speech if you listen binaurally). As far as I understand this should be different (albeit related) to the BMLD effect. Manfred Schroeder cites the following patent which is supposed to be able to generate this effect: http://www.ptodirect.com/Patents/3328526 Does anyone know a sound sample or even a piece of source code that demonstrates this effect? I think it would be a wonderful effect to demonstrate the fascinating binaural processing that goes on in our brains. Thanks in advance for any reply!
