Evaluation of the audio quality a listener perceives is an important issue for all those involved in audio recording and reproduction. The variety of tools in audio work facilitates advanced processing of the audio signal. The aims of these processes differ, but they all in some way, sooner or later give rise to the question of in which way the audio(More)
The subjective effects of controlled high frequency limitation of the audio bandwidth on assessment of audio quality were studied. The investigation was focused on the standard 5.1 multichannel audio set-up (Rec. ITU-R BS.775-1) and limited to the optimum listening position. The effect of video presence on audio quality assessment was also investigated. The(More)

Two objective measurement techniques have been proposed that relate the fluctuations in interaural time difference to one or more attributes of subjective spatial perception. This paper reviews these measurements, discusses how these fluctuations may be created in a real acoustical environment, summarises the experiments carried out to elicit the subjective(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)
When the spatial quality of reproduced sound is to be assessed, knowledge of the dimensions forming the quality is essential since the quality is known to be multi-dimensional. The dimensions could be indicated by attributes describing them. Attributes encountered during a previous experiment are considered by a group of subjects and their responses are(More)

Assessment of the spatial quality of reproduced sound is becoming more important as the number of techniques and systems affecting such quality increases. The presence of dimensions forming spatial quality has been indicated in earlier experiments by using attributes as descriptors for the dimensions. These attributes have been found relevant for describing(More)
