—This paper seeks to present an algorithm for the prediction of frontal spatial fidelity and surround spatial fidelity of multichannel audio, which are two attributes of the subjective parameter called basic audio quality. A number of features chosen to represent spectral and spatial changes were extracted from a set of recordings and used in a regression(More)
The evaluation of perceived spatial quality calls for a method that is sensitive to changes in the constituent dimensions of that quality. In order to devise a method accounting for these changes, several processes have to be performed. This paper shows the development of scales by elicitation and structuring of verbal data, followed by validation of the(More)

In the search for suitable ways to assess the spatial performance of sound reproducing systems, various research methods from the fields of psychology and the behavioural sciences may be considered. Selected approaches are reviewed, with particular emphasis on the Repertory Grid Technique (RGT). A pilot experiment relating to spatial parameters, inspired by(More)
Previous research has indicated that the relationship between the interaural cross-correlation coefficient (IACC) of a narrow-band sound and its perceived auditory source width is dependent on its frequency. However, this dependency has not been investigated in sufficient detail for researchers to be able to properly model it in order to produce a(More)
The effect of division of attention between the evaluation of multichannel audio quality and involvement in a visual task (playing a computer game) was investigated. It was observed that involvement in a visual task may significantly change the results obtained during evaluation of audio quality for some listeners and for some experimental conditions. It(More)
