scope:

The focus of this Recommendation is on test methods involving test participants, which collect subjective ratings, task performance measures, and/or descriptors of communication aspects. For that purpose, this Recommendation extends the testing procedures for telemeeting systems described in [ITU-T P.1301] by specifying test methods dedicated to spatial audio telemeeting systems and - where appropriate - referring to stand-alone methods that are also suitable for spatial audio, which are [ITU-T P.1311], [ITU-T P.1312]. Further test methods related to spatial audio will be under study within ITU and this Recommendation will be updated with the relevant references when new methods are available.

In addition, this Recommendation also provides some guidance on testing spatial audio systems which include video communication. The focus is on the perceived alignment of the audio and the video source locations.
