The subjective effects of interchannel phase-shifts on the stereophonic image localisation of wideband audio signals

摘要

This report describes a series of subjective tests concerned with the effects of interchannel phase-shifts on stereophonic image localisation. The tests, involving listeners experienced in subjective auditory judgements, were carried out in both a free-field room and a listening room,nQuantitative information is given on the effects of phase-shifted signals on image position and spread In addition subjective data is given on the acceptability of such signals in programme material The results are of relevance to the stereo compatibility of matrix quadraphonic systems. In addition, they may prove useful in producing novel spatial effects for use in normal stereophony.
