"Most current perceptual models for audio quality have so far tended to 
concentrate on the audibility of distortions and noises that mainly affect 
the timbre of reproduced sound. The QESTRAL model, however, is specifically 
designed to take account of distortions in the spatial domain such as 
changes in source location, width and envelopment. It is not aimed only at 
codec quality evaluation but at a wider range of spatial distortions that 
can arise in audio processing and reproduction systems. The model has been 
calibrated against a large database of listening tests designed to evaluate 
typical audio processes, comparing spatially degraded multichannel audio 
material against a reference. Using a range of relevant metrics and a 
sophisticated multivariate regression model, results are obtained that 
closely match those obtained in listening tests."
