Audio rendering for low frequency effects

Abstract:

In general, various aspects of the techniques are directed to audio rendering for low frequency effects. A device comprising a memory and a processor may be configured to perform the techniques. The memory may store audio data representative of a soundfield. The processor may analyze the audio data to identify spatial characteristics of low frequency effects components of the soundfield, and process, based on the spatial characteristics, the audio data to render a low frequency effects speaker feed. The processor may also output the low frequency effects speaker feed to a low frequency effects capable speaker.
