Summary:
|
This Recommendation describes an objective method for predicting overall listening speech quality from narrowband (300 to 3'400 Hz) to super-wideband (50 to 14'000 Hz) telecommunication scenarios as perceived by the user in a P.800 or P.830 ACR listening only test. P.863 supports two operational modes, one for narrowband and one for super-wideband. This Recommendation presents a high-level description of the method, advice on how to use it, and part of the results from a Study Group 12 benchmark carried out in the period 2006-2010. A C++ reference implementation, described in Annex B, is provided in separate files and forms an integral part of this Recommendation. A conformance testing procedure is also specified in Annex A to allow a user to validate that an alternative implementation of the model is correct. The C++ reference implementation shall take precedence in case of conflicts between the high-level description as given in this Recommendation and the C++ reference implementaion.
This Recommendation includes an electronic attachment containing a C++ reference implementation of POLQA and conformance testing data.
