Adaptive audio construction

A method for creating an object-based audio signal from an audio input, the audio input including one or more audio channels that are recorded to collectively define an audio scene, the one or more audio channels being captured from a respective one or more spatially separated microphones disposed in a stable spatial configuration, the method including the steps of:

• a) receiving, by a spatial audio analysis module, the audio input;
• b) performing spatial analysis on the one or more audio channels to identify one or more audio objects within the audio scene;
• c) determining contextual information relating to the one or more audio objects, wherein the contextual information includes spatial properties of the one or more audio objects;
• d) defining respective audio streams including audio data relating to at least one of the identified one or more audio objects;
• e) outputting, by the spatial audio analysis module, an object-based audio signal including the audio streams and the contextual information;
• f) receiving, by an automated effects processing module, the object-based audio signal;
• g) performing effects processing on one or more of the audio streams to generate a modified object-based audio signal, wherein the effects processing is based on the contextual information and on external context information that is external to the audio signal, and wherein the effects processing includes performing Doppler frequency shifting for a given audio stream based on the spatial properties included in the contextual information;
• and
• h) outputting, by the automated effects processing module, the modified object-based audio signal as an encoded signal.
