Dear all, I would like to share several software tools that I developed over several years for myself and colleagues for psychoacoustic research and education. All are free of charge (unless you want to pay!) and distributed under Academic Free License 3.0. A paper has been published in Behavioral Research Methods Here’s the link for further information and downloads: Graduate students might find one of the programs, Psycon, particularly useful. You can define your own signals to examine or process and start a psychophysical paradigm such as the adaptive procedure for your studies right away. You define or specify signals in AUditory syntaX (AUX), specifically created to handle auditory signals. You do not need to be a programmer or a "techie" to use this. All you need is to think about what sounds you are going to use (e.g., a brief tone followed by bandpass-filtered noise, a recorded speech material in the background a harmonic tone complex, or certain temporal pattern of tones or noise that you want to arrange) and write an AUX code then you are ready for an experiment. From my experience so far, on average, most Psycon users without a programming background were able to write AUX codes on their own after 10-20 minutes of introduction. AUX provides a whole gamut of programming, so there are features that experienced programmers in C/C++ or MATLAB could appreciate. Moreover, experienced programmers are encouraged to develop AUX-based programs on their own using AUX Library tools (i.e., if you think AUX is OK but Psycon is not, you can make your own programs with these tools). As of now, documents on the website still need some improvements but most contents can be found somewhere. If you have any questions, please email me.
