Direction of arrival estimation for multiple audio content streams

A method of reproducing a virtual sound environment, comprising:

• receiving an audio signal;
• generating a plurality of filters based on the audio signal, each of the filters corresponding to one of a plurality of sound content categories, the sound content categories including a target sound content category and one or more ambient sound content categories;
• and
• separating the audio signal into a plurality of category specific audio signals using the filters, the category specific audio signals includes a target category specific audio signal of the target sound content category and one or more ambient category specific audio signals of the ambient sound content categories;
• for each of the category specific audio signals, generating a direction of arrival (DOA) for a sound source of the category specific audio signal and a probability value indicating a likelihood of the DOA of the sound source;
• and
• reproducing a virtual sound environment by replaying the category specific audio signals using a plurality of speakers, wherein for each of the category specific audio signals, designation of one or more of the speakers that replay the category specific audio signal and determination of replay parameters are based on the DOA of the sound source of the category specific audio signal.
