Title: Spatial audio processing
Inventor: ANTTI JOHANNES ERONEN
IPC: H04S7/00
Filed: 2017-04-24
Abstract: A method 400 for automatically changing an allocation of frequency sub-channels (51, fig 4) to multiple output audio channels (52, fig 4). The frequency sub-channels are of an input audio signal (113, fig 4), and each output audio channel is for rendering at a location within a sound space (10, fig 1). The allocation of frequency sub-channels is automatically changed, and may be in response to one or more changes in a power spectrum of the input audio signal. The automatic change may be in response to an automatic detection of a sub-optimal allocation such as by comparing cost function values of current and putative/alternative allocations. The method may have the steps of automatically determining a first power spectral density function 404 for the input audio signal (Fig 8A); automatically determining a second power spectral density function 414 for each of the allocated putative frequency sub-channels (Figs 8B-8E), performing a running average smoothing over frequency bins using a sliding window for first and second functions 406, 416, comparing the functions 420, and determining whether the putative allocation is better than the current allocation 422 using a mean square error value.
