Claim 14:
15. A method comprising:
obtaining at least one ambience component representation, the ambience component representation comprising at least one respective diffuse background audio signal and at least one parameter, the at least one parameter associated with
the at least one respective diffuse background audio signal,
at least one frequency range or at least one part of the at least one frequency range,
at least one time period or at least one part of the at least one time period, and
a directional range for a defined position within an audio field,

wherein the at least one parameter comprises at least one parameter based, at least partially, on removal of directional audio components associated with at least one close audio signal, associated with an audio source, from at least one energy parameter determined based on analysis of at least two audio signals captured with a microphone array;
obtaining at least one of: a rendering position, or a rendering direction within an audio field; and
rendering at least one ambiance audio signal, comprising processing the at least one respective diffuse background audio signal based on
the at least one parameter, and
the at least one of: the rendering position, or the rendering direction relative to the defined position within the audio field.
