Data on EEG, EDA, BVP, psychological responses and audio files used for the study of 3D Audio Immersive Experience

The data described in this repository has five items:DataSpecsThis excel file has six worksheets with the following information: demographic data, biofiles available, Immersive Tendencies Questionnaire responses, immersive questionnaire responses, items of questionnaires, and EEG electrode positions in Theta/Phi coordinates.LoudspeakerInformationPDF file explaining the alignment and positions of loudspeakers for stereo, PCMA-3D, and ESMA-3D audio playback. RawDataFolder with individual subfolders of participants labeled with assigned ID. Each folder has EEG, EDA, and BVP files in GDF format for three conditions: 1) resting state (Bl), 2) concert hall (Music), and 3) urban park (Park) soundscapes. The assigned audio group (Stereo or 3D) is specified in file names. Sample rates are: EEG = 500 Hz, BVP = 64 Hz, and EDA = 4 Hz. The assigned audio group is specified in file names. For example, file “01_Stereo_BVP_Bl” corresponds to BVP data in the resting state of the participant 01 assigned to the Stereo group.LatencyAdjustmentFolder with individual subfolders of participants labeled with assigned ID in SET/FDT format. The only difference is that "condition 8" onset was adjusted according to the latency caused by the distance between the audio system and participants (2 m). Condition 8 indicates the moment a soundscape (Music or Park) was played.<br>AudioFilesThis folder contains two subfolders:Music: 2-minute long WAV audio files of concert hall recordings prepared to be heard on PCMA-3D and Stereo (<i>Downmix files</i>) loudspeaker array at 48k Hz of sample rate and 24-bit depthPark: 2-minute long WAV audio files of urban park recordings prepared to be heard on ESMA-3D and Stereo (<i>Downmix files</i>) loudspeaker array at 48k Hz of sample rate and 24-bit depthStereo downmix files include the word “_Downmix_”.Note: In the worksheet Items of DataSpecs, the codes that the questionnaires provide are included. Just one item of the Immersive Tendencies Questionnaire and the items of the Self-assessment manikin test do not have codes in their original publications.
