Publication number: 20190387346Abstract: Systems, methods, and computer program products of preparing an audio signal for playback on a monaural playback device A system receives an audio signal including one or more components, the one or more components including sound from one or more audio sources. The system processes the audio signal to create a monaural signal. The processing includes introducing one or more monaural cues into at least one component of the one or more components. The monaural signal maintains a presence of the one or more monaural cues. The system then provides the monaural signal to the monaural playback device or to a storage device. The one or more monaural cues are such that, if the monaural signal is played back to a listener using the monaural playback device, the listener experiences a perceived differentiation in direction of the one or more components and/or the one or more audio sources.Type: ApplicationFiled: June 13, 2019Publication date: December 19, 2019Applicant: Dolby Laboratories Licensing CorporationInventors: Mark David DE BURGH, Timothy Alan PORT, David Matthew COOPER

Publication number: 20190327575Abstract: A system and method of modifying a binaural signal using headtracking information. The system calculates a delay, a first filter response, and a second filter response, and applies these to the left and right components of the binaural signal according to the headtracking information. The system may also apply headtracking to parametric binaural signals. In this manner, headtracking may be applied to pre-rendered binaural audio.Type: ApplicationFiled: June 20, 2017Publication date: October 24, 2019Applicant: DOLBY LABORATORIES LICENSING CORPORATIONInventors: C.

Patent number: 8582783Abstract: A signal from each of an array of microphones is analyzed. For at least one subset of microphone signals, a time difference is estimated, which characterizes the relative time delays between the signals in the subset. A direction is estimated from which microphone inputs arrive from one or more acoustic sources, based at least partially on the estimated time differences. The microphone signals are filtered in relation to at least one filter transfer function, related to one or more filters. A first filter transfer function component has a value related to a first spatial orientation of the arrival direction, and a second component has a value related to a spatial orientation that is substantially orthogonal in relation to the first. A third filter function may have a fixed value. A driving signal for at least two loudspeakers is computed based on the filtering.Type: GrantFiled: April 6, 2009Date of Patent: November 12, 2013Assignee: Dolby Laboratories Licensing CorporationInventors: David Stanley McGrath, David Matthew Cooper
