Scope

Recommendation ITU-T P.863 is specified for the prediction of Listening Quality of acoustically recorded speech data in a super-wideband context only. That means the reference signal in this context is always a super-wideband speech signal and P.863 is used in super-wideband operational mode. This Appendix III to ITU-T P.863 gives advices how ITU-T P.863 can be used for the prediction of Listening Quality of acoustically recorded speech data in a narrowband context. Narrowband context means that the reference signal is narrowband. The prediction is using a narrowband scale and P.863 predicts as a listener in a pure narrowband listening test.
