Assessments from 23 subjects are available for the 6 recorded and 19 simulated scenes, and from 7 to 8 subjects for the 75 simulated scenes.
The contents of this dataset are as follow:
assessments: contains evaluations by 23 subjects of perceptual scales on the corpus
sXX: Folder corresponding to participant XX
Pt_.txt: Contains assessments. Each line corresponds to one scene, columns correspond to (resp.) scene number (see audio_list.txt for correspondance), pleasantness, liveliness, overall loudness, interest, calmness, sound level of passing vehicles, time of presence of traffic, human voices, bird sources.
rec: contains the 6 recorded 45s scenes
rep: contains the 19 replicated 45s scenes, with separated tracks for source contributions
sim: contains the 75 simulated 45s scenes, with separated tracks for source contributions
audio_list.txt: list of audio files in the corpus, line ordering corresponds to numbers in the first column of assessments
rep_exp.mat, sim_exp.mat: Additional information about the corpus, with playback Leq and physical estimations of the perceptual time of presence of sources for each scene.
