Distributed Audio Capture and Mixing

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, causes the apparatus at least to:
• determine a spatial audio signal captured by a microphone array at a first position configured to provide spatial audio capture;
• determine at least one additional audio signal captured by an additional microphone at a second position;
• determine and track a relative position between the first position and the second position;
• determine a variable delay between the spatial audio signal and the at least one additional audio signal such that common components of the spatial audio signal and the at least one additional audio signal are time aligned;
• apply the variable delay to the at least one additional audio signal to substantially align the common components of the spatial audio signal and at least one additional audio signal;
• and
• determine at least one source parameter classifying an audio source associated with the common components and/or at least one space parameter identifying an environment within which the audio source is located based on the at least one additional audio signal.

A method comprising:

• receiving a spatial audio signal associated with a microphone array configured to provide spatial audio capture and at least one additional audio signal associated with an additional microphone, the additional audio signal having been delayed by a variable delay determined such that common components of the spatial audio signal and the at least one additional audio signal are time aligned;
• receiving a relative position between a first position associated with the microphone array and a second position associated with the additional microphone;
• receiving at least one source parameter classifying an audio source associated with the common components and/or at least one space parameter identifying an environment within which the audio source is located;
• determining at least one processing effect ruleset based on the at least one source parameter and/or the at least one space parameter;
• generating at least two output audio channel signals by mixing and applying at least one processing effect to the spatial audio signal and the at least one additional audio signal based on the at least one processing effect ruleset.
