Subject: Multi-Listener Psychophysics in MATLAB From: Tony Miller <ajmiller@xxxxxxxx> Date: Tue, 21 Nov 2006 16:42:08 -0500 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>List members- I'm posting this, in the rarest of hope, that I can save someone a lot of time and effort if they happen to be working on a similar problem. Previously, Aaron Hastings helped me tremendously with his posting on a MATLAB script for the ISO 532B standard (http://www.auditory.org/mhonarc/2000/msg00498.html). Our group was looking for a MATLAB based method for collecting user opinion from 12 listeners in real-time. What we finally settled on is a solution from P.I. Engineering in Williamston, Michigan. They sell a fully programmable, USB based, Keypad with an LCD screen and accompanying software development kit. This allows us to collect user data from up to 128 users over the USB interface directly into MATLAB using Microsoft Windows ActiveX commands. If you are interested, here is where you can find more information...
