Software for psychoacoustics--Psycon & AUX
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 http://www.springerlink.com/content/t83x56u66pm29p42/. Hereâs
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.
