Spatial comfort noise
First Claim
1. A method, in a receiving endpoint of a conference system, of providing spatial comfort noise, the method comprising:
- receiving one or more audio signals for rendering at the receiving endpoint over a network connection to a server;
generating one or more noise signals;
adjusting the one or more noise signals to modified noise signals that have target spectral characteristics typical of comfort noise;
adjusting the modified noise signals to form a plurality of spatial comfort noise signals having at least one spatial property that at least substantially matches at least one target spatial property, the adjusting the modified noise signals comprising converting the one or more noise signals to a soundfield format;
combining the received audio signals with the plurality of spatial comfort noise signals; and
rendering the spatial comfort noise signals to a set of output signals for loudspeakers to be heard by one or more conferees at the receiving endpoint, wherein the rendering renders the combination of the received audio signals and the spatial comfort noise signals to the set of output signals for loudspeakers.

Abstract
A method, an apparatus, logic (e.g., executable instructions encoded in a non-transitory computer-readable medium to carry out a method), and a non-transitory computer-readable medium configured with such instructions. The method is to generate and spatially render spatial comfort noise at a receiving endpoint of a conference system, such that the comfort noise has target spectral characteristics typical of comfort noise, and at least one spatial property that at least substantially matches at least one target spatial property. On version includes receiving one or more or more audio signals from other endpoints, combining the received audio signals with the spatial comfort noise signals, and rendering the combination of the received audio signals and the spatial comfort noise signals to a set of output signals for loudspeakers, such that the spatial comfort noise signals are continually in the output signal sin addition to output from the received audio signals.

5. A non-transitory computer-readable medium configured with instructions that when executed by one or more processors of a processing system included in a receiving endpoint of a conference system, carry out a method of providing spatial comfort noise, the method comprising:
-
receiving one or more audio signals for rendering at the receiving endpoint over a network connection to a server; generating one or more noise signals; adjusting the one or more noise signals to modified noise signals that have target spectral characteristics typical of comfort noise; adjusting the modified noise signals to form a plurality of spatial comfort noise signals having at least one spatial property that at least substantially matches at least one target spatial property, the adjusting the modified noise signals comprising converting the one or more noise signals to a soundfield format; generating a combination of the plurality of spatial comfort noise signals and a plurality of audio signals received at the receiving endpoint from a sending endpoint; and rendering the combination of the received audio signals and the spatial comfort noise signals to a set of output signals for loudspeakers, wherein the rendering renders the combination of the received audio signals and the spatial comfort noise signals to the set of output signals for loudspeakers.
