The MAT-files contain the aligned EEG and audio data for each subject (N=22). The envelopes of the speech audio (without noise) have been extracted as described in the paper. Each file (data_N.mat) contains a Matlab struct in the format of the Fieldtrip toolbox containing the following fields:

data.trial:           EEG and audio data for all 40 trials [channels x timepoints]

• channels 1-64: scalp EEG
• channel 65: left mastoid electrode
• channel 66: right mastoid electrode
• channel 67: horizontal EOG
• channel 68: vertical EOG for left eye
• channel 69: vertical EOG for right eye
• channel 70: audio envelopes

data.trialinfo:     Experimental condition in each trial

• 1 = low noise, 1-back
• 2 = low noise, 2-back
• 3 = high noise, 1-back
• 4 = high noise, 2-back

data.time:          Sample indices for each trial in seconds

data.label:         Name of each channel in data.trial

data.fsample:    EEG/audio sampling rate in Hz (128)
