Please make sure you read this post before asking for help. No one can help you unless you provide a clear description of the software environment you are using and your programming problem…

Please ask questions relating to the use of hardware devices like audio cards, input/output (I/O) hardware and GPU specific questions here. Please make sure you provide full details about the hardware, and your OS / MATLAB | Octave version / PTB version etc.

This category allows more experienced PTB users to provide small tips or tricks when using PTB.

Please post bugs you think you may have found or potential feature requests here. But please be aware that PTB is open source and there is is only one main developer who contributes their spare time to this project–be kind and have reasonable expectations.
