Predicting the perceived spatial quality of sound processing and reproducing equipment
A method and system for predicting the perceived spatial quality (e g. azimuth angle, envelopment) of sound processing and reproducing equipment comprises: measuring or recording the response of a device under test (DUT) to one or more test signals; applying one or more metrics to the reproduced signal(s) to obtain a higher-level representation of the raw data obtained from the DUT to extract a physical measure of the spatial quality; performing calibration by establishing a relationship/correlation between the physical measure and spatial quality assessments obtained from listening tests carried out on real listeners; applying the relationship to obtain a prediction of the perceived spatial quality provided by the DUT. Further embodiments apply the test signal(s) to a reference device and applying metrics to the output signal of the reference device, wherein the difference between the outputs of the DUT and reference device form a relative measure for predicting a difference between spatial attributes of the DUT and reference device by calibrating the relative measure with ratings obtained from listening tests.
