Subject: Re: [AUDITORY] Question on Daniel & Weber (1997) roughness model From: Alejandro Osses <ale.a.osses@xxxxxxxx> Date: Fri, 6 Mar 2020 11:03:02 +0100 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>--0000000000000b4ce005a02cc34e Content-Type: text/plain; charset="UTF-8" Dear Stephen, hello, The Daniel & Weber model is already implemented in MATLAB. It is available within the PsySound3 toolbox (http://psysound.wikidot.com/). The code was programmed by my former colleague from Eindhoven Prof. Dik Hermes. The model is implemented in a very transparent way, I was able to reproduce very faithfully at some point (a couple of years ago) almost all figures from the Daniel & Weber paper. Regarding the code itself, it is possible to extract the codes from PsySound (each "analyser" within the toolbox is stored in a different folder) to use the model without having to run the graphical interface. I can provide that "stand-alone code" if your colleague is interested... Please have a look at the code and I will be happy to provide further feedback/support to you or your colleague.
