"This paper describes the development of an unintrusive objective model, 
developed independently as a part of the QESTRAL project, for predicting 
the sensation of envelopment arising from commercially available 5-channel 
surround sound recordings. The model was calibrated using subjective scores 
obtained from listening tests that used a grading scale defined by audible 
anchors. For predicting subjective scores, a number of features based on 
Interaural Cross Correlation (IACC), Karhunen-Loeve Transform (KLT) and 
signal energy levels were extracted from recordings. The ridge regression 
technique was used to build the objective model and a calibrated model was 
validated using a listening test scores database obtained from a different 
group of listeners, stimuli and location. The initial results showed a high 
correlation between predicted and actual scores obtained from the listening 
tests."
