Git (hosted on GitHub) as code management system: All changes are archived and documented. Version 2 originally written for Apple MacOS by Denis Pelli and David Brainard, released around Later a more limited release for MS-Windows around Version 3, a complete rewrite of the low-level C layer and many high level functions: Since 2004 for Apple OSX by Allen Ingling of the Pelli Lab at CNS - New York University Since 2006 for MS-Windows & GNU/Linux by Mario Kleiner of the Buelthoff lab, MPI for Biological Cybernetics, Tuebingen, Germany.

Free open source software (FOSS), licensed mostly under the MIT license. A couple of hundred Matlab M-Files to simplify higher level tasks like data analysis, logging of responses to files, monitor calibration. Compiled Plugins (written in C) for time critical operations and interfacing with graphics-, sound- and response collection hardware and operating system services. Psychtoolbox: Extensions for Matlab and Octave with functions for precise and flexible stimulus presentation and response collection.ĥ Psychtoolbox-3: What is it? A set of Matlab/Octave extensions to facilitate programming of psychophysics experiments in Mathworks proprietary Matlab(tm) or the free and open source GNU/Octave.

Insufficient level of control, timing precision and performance for psychophysics out of the box. Middle ground: Interpreted languages like Matlab or Python: Easy to learn and flexible. Considerable lack of flexibility for demanding tasks. Considerable knowledge about underlying operating systems and (computer-)hardware needed to use effectively! High-level canned experiment packages: Easy to learn & use. Difficult and time consuming to learn and use. Low-level programming languages and API's: Very flexible. Robust timing for stimulus presentation and response collection. Visual stimulus presentation basics: Basic drawing functions, coordinates, colors Visual stimulus onset, timing and timestamping Advanced drawing functions Stimulus post processing and special display hardware Auditory stimulus presentation basics Response collection basicsĤ Motivation Requirements for typical experimental studies in cognitive science: Accurate and flexible control of stimulus properties.

The following code shows how to use tgrabaudio to input sound in To call tgrabaudio('stop') as soon as possible (either manually or using Uses tgrabaudio crashes before calling tgrabaudio('stop'), don't forget Careful, if this step is omitted, Matlab is likely to crash orīehave strangely the next time tgrabaudio is run. This clears the persistent variables and stops the background audio

N = the number of samples to be "grabbed". If this buffer isĮxceeded during auditory capture, an error will be generated. Maxduration = the maximum delay (in seconds) that is considered anĪcceptable build-up of audio samples. In the meantime, the detailed function of tgrabaudio.m is described in its help section, copied below for convenience: Can anyone confirm that PsychPortAudio works for realtime audio input?

PsychPortAudio ( ): This may be the best option, although it requires PsychToolbox, which can be challenging to install itself. However, support seems to have ended around 2008, and I know several people who have spent many hours failing to compile it for more recent operating systems and/or Matlab versions. PlayRec.m ( ): An adaptation of PortAudio for Matlab. PortAudio ( ): seem to be the workhorse of audio input, but it's in C++, not Matlab code I hope to be able to report at some point that this function has been superceded by something more generally useful, so please let me know if you come across something better. Unfortunately this solution requires Windows and the Data Acquisition toolbox. I explored different options for realtime audio input (see below for a summary) before having to settling for this option.
