In virtual acoustics or artificial reverberation, impulse responses can be split so that direct and reflected components of the sound field are reproduced via separate loudspeakers. The authors had investigated the perceptual effect of angular separation of those components in commonly used 5.0 and 7.0 multichannel systems, with one and three sound sources respectively (Kleczkowski et al., 2015, J. Audio Eng. Soc. 63, 428-443). In that work, each of the front channels of the 7.0 system was fed with only one sound source. In this work a similar experiment is reported, but with phantom sound sources between the front loudspeakers. The perceptual advantage of separation was found to be more consistent than in the condition of discrete sound sources. The results were analysed both for pooled listeners and in three groups, according to experience. The advantage of separation was the highest in the group of experienced listeners.

“…Previousr esearch on the quality of perceiveda udio, which is one of the modalities under investigation, shows that it has been successfully evaluated. These data collection methods often deal with rating scales [8,9,10,11,12] and descriptive analyses and use the subject'sown vocabulary to evaluate the perceiveda udio quality [13]. What all these methods have in common is that theyall are conducted in laboratory settings and followa ne xperimental paradigm.…”

SummaryThis study presents aq ualitative method for collecting and analysing data to describe audio and video quality. Used in the social sciences, arts, and humanities, this approach relies on phenomenology and hermeneutics and uses interviews and questionnaires to assess the audio and video quality of master classes in classical music taught via the Internet. Although this study is only exploratory,itprovides evidence that the method could successfully be used to gather descriptions of perceivedqualities.

Assessing the quality of audio signals is an important consideration in making high quality sounds and various methods have been developed. This paper provides a general framework of sound quality and a technical overview of the international standard methods which are described in ITU-T, ITU-R, IEC and ANSI Recommendations in the speech intelligibility, speech quality, and audio quality areas. In addition, some recent findings and future works are included.
