Abstract
Example techniques relate to primary-ambient playback of surround audio by audio playback devices. Example playback devices described herein may include multiple speakers, such as a forward-firing audio transducer and side-firing audio transducers. Using example techniques, such playback devices may perform primary-ambient decomposition to separate surround channels into primary' and ambient channels. The playback devices play back the ambient channel(s) via the side-firing transducers and the primary channel via the forward-firing transducer.
