Details

The data were collected within a series of experiments conducted at the Sound Quality Research Unit (SQRU), Department of Acoustics, Aalborg University, Denmark, between September 2004 and March 2005.

The results of scaling listener preference and spatial and timbral auditory attributes are reported in Choisel and Wickelmaier (2007).

Details about the loudspeaker setup and calibration are given in Choisel and Wickelmaier (2006).

The attribute elicitation procedure is described in Wickelmaier and Ellermeier (2007) and in Choisel and Wickelmaier (2006).

The selection of listeners for the experiments is described in Wickelmaier and Choisel (2005).

Format

A data frame containing 783 observations on 6 variables.

id

Factor. Listener ID.

time

Factor. Listening experiment before or after elicitation and scaling of more specific auditory attributes.

progmat

Factor. The Program material: Beethoven, Rachmaninov, Steely Dan, Sting.

repet

The repetition within each time point.

session

The experimental session coding the presentation order of the program material.

preference

Paired comparison of class paircomp. Preferences for all 28 paired comparisons from 8 audio reproduction modes: Mono, Phantom Mono, Stereo, Wide-Angle Stereo, 4-channel Matrix, 5-channel Upmix 1, 5-channel Upmix 2, and 5-channel Original.
