1. A method comprising:
- accessing, by a user device, a location corresponding to at least one microphone array in a content of a free-viewpoint audio environment;
tracking user movement of a user based on a user position in the content of the free-viewpoint audio environment;
determining user displacement from a nearest microphone array of the at least one microphone array;
determining a probability of error in a direction estimate from at least one part of an audio signal; and
applying audio ambience to the at least one part of the audio signal based on the user displacement from the nearest microphone array of the at least one microphone array and the probability of error in the direction estimate from the at least one part of the audio signal.

10. An apparatus comprising:
-
at least one processor; and at least one non-transitory 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 to; access a location corresponding to at least one microphone array in a content of a free-viewpoint audio environment; track user movement of a user based on a user position in the content of the free-viewpoint audio environment; determine user displacement from a nearest microphone array of the at least one microphone array; determine a probability of error in a direction estimate from at least one part of an audio signal; and apply audio ambience to the at least one part of the audio signal based on the user displacement from the nearest microphone array of the at least one microphone array and the probability of error in the direction estimate from the at least one part of the audio signal. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A non-transitory program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine for performing operations, the operations comprising:
-
accessing, by a user device, a location corresponding to at least one microphone array in a content of a free-viewpoint audio environment; tracking user movement of a user based on a user position in the content of the free-viewpoint audio environment; determining user displacement from a nearest microphone array of the at least one microphone array; determining a probability of error in a direction estimate from at least one part of an audio signal; and applying audio ambience to the at least one part of the audio signal based on the user displacement from the nearest microphone array of the at least one microphone array and the probability of error in the direction estimate from the at least one part of the audio signal.
