NJU Auditory Attention Decoding Dataset

This is an auditory attention decoding dataset including EEG recordings of 21 subjects when they were instructed to attend to one of the two competing speakers at two different locations. Unlike previous datasets (such as the KUL dataset), the locations of the two speakers are randomly drawn from fifteen alternatives.All subjects have given formal written consent approved by the Nanjing University ethical committee before the experiment and received financial compensation upon completion.The EEG data were recorded with the 32-channel EMOTIV Epoc Flex Saline system at a sampling rate of 128 Hz (downsampled from 1024 Hz) in a low-reverberant listening room.For each subject, the experiment includes 32 trials. In each trial, the subject was exposed to a pair of randomly selected stimuli, the directions of whom were randomly drawn from the 15 possible competing speaker directions, i.e., ±135°, ±120°, ±90°, ±60°, ±45°, ±30°, ±15° and 0°.This dataset provides the preprocessed EEG recordings and the aligned audio stimuli signals, as long as the attention information. All data are provided as zipped files.Please contact the author at [e-mail] for additional information.Note that there are 28 subjects participated in our experiments and the data of seven subjects were removed from further analysis due to device failure.
