20090042565 | CONNECTION POINT TRIGGERED SCANNING FOR POSITIONING RADIOS - A system for automatically controlling the scanning frequency of a radio based positioning application in a wireless communication device (WCD) based on the connection point information of the WCD. The connection point information may be utilized to identify if the WCD is near a positioning-enabled environment. Scanning may be activated, or the scanning frequency may be increased, when the WCD is in an environment that is served by certain connection points (e.g., connection points located in a city). On the other hand, when the WCD is in an environment that is not served by certain connection points (e.g., a rural area), scanning may be stopped or the scanning frequency may be reduced to conserve power in the mobile device. | 02-12-2009 |

20080298610 | Parameter Space Re-Panning for Spatial Audio - Aspects of the invention provide methods, computer-readable media, and apparatuses for re-panning multiple audio signals by applying spatial cue coding. Sound sources in each of the signals may be re-panned before the signals are mixed to a combined signal. Processing may be applied in a conference bridge that receives two omni-directionally recorded audio signals. The conference bridge subsequently re-pans one of the signals to the listeners left side and the signal to the right side. The source image mapping and panning may further be adaptively based on the content and use case. Mapping may be done by manipulating the directional parameters prior to directional decoding or before directional mixing. Directional information that is associated with an audio input signal is remapped order to compress input source positions into virtual source positions. The virtual sources may be placed with respect to actual loudspeakers using binaural cue panning. | 12-04-2008 |
20090116652 | Focusing on a Portion of an Audio Scene for an Audio Signal - Aspects of the invention provide methods, computer-readable media, and apparatuses for spatially manipulating sound that is played back to a listener over a set of output transducers, e.g., headphones. The listener can direct spatial attention to focus on a portion of an audio scene, analogous to a magnifying glass being used to pick out details in a picture. An input multi-channel audio signal that is generated by audio sources is obtained, and directional information is determined for each of the audio sources. The user provides a desired direction of spatial attention so that audio processing can focus on the desired direction and render a corresponding multi-channel audio signal to the user. A region of an audio scene is expanded around the desired direction while the audio scene is compressed in another portion of the audio scene. | 05-07-2009 |
