20 Claims

1. An apparatus comprising:

at least one processor; and

at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform:

assessing a continuity of audio service by comparing a previous audio service with a first spatial audio service that uses user head-tracking and a second audio service to identify which of the first spatial audio service and the second audio service provides a continuity of audio service with respect to the previous audio service;

selectively enabling the first spatial audio service if it is assessed to provide continuity of audio service; and

selectively enabling the second audio service if it is assessed to provide continuity of audio service,

wherein the first spatial audio service controls or sets at least one directional property of at least one sound source and wherein the first spatial audio service is assessed to provide continuity of audio service if it can use head-tracking to control or set the at least one directional property of at least one sound source, such that at least one directional property of at least one sound source rendered by the previous audio service is reproduced by the first spatial audio service using head-tracking.
