Patent number: 8737645Abstract: One example embodiment increases perceived signal strength of a sound signal based on persistence of hearing. When the ear perceives a signal it takes a finite length of time to process it. During that time period the ear does not recognize input and is, in effect, “Turned Off”. In accordance with one aspect of the technology, these periods of “unheard” audio input are utilized so that they supplement the information which the ear sends to the brain. An exemplary system includes a switch, configured to route the audio alternatively to two signal paths—one which includes a delay circuit that delays that audio by an amount equal to the ear's persistence of hearing interval. The system also includes a signal combiner configured to combine outputs from the two signal paths, so as to provide the brain with a signal that it will perceive as being twice as loud as the original.Type: GrantFiled: October 10, 2012Date of Patent: May 27, 2014Inventor: Archibald Doty

Publication number: 20140133677Abstract: A interface circuit for an acoustic transducer provided with a first detection structure and a second detection structure has: a first input and a second input; a first processing path and a second processing path coupled, respectively, to the first input and second input and supply a first processed signal and a second processed signal; and a recombination stage, which supplies a mixed signal by combining the first processed signal and the second processed signal with a respective weight that is a function of a first level value of the first processed signal. The first and second inputs receive a respective detection signal associated, respectively, to the first detection structure and to the second detection structure of the acoustic transducer; and an output stage the first processed signal, the second processed signal or the mixed signal, on the basis of a second level value of the first processed signal.Type: ApplicationFiled: July 5, 2013Publication date: May 15, 2014Inventors: Martino Zerbini, Luca Molinari

Patent number: 8725279Abstract: A method and apparatus for processing an audio signal is disclosed. Herein, the method includes receiving a downmix information having at least one independent object and a background object downmixed therein; receiving an object information and a mix information; and extracting at least one independent object from the downmix information using the object information and the enhanced object information.Type: GrantFiled: March 17, 2008Date of Patent: May 13, 2014Assignee: LG Electronics Inc.Inventors: Hyen O Oh, Yang Won Jung

Publication number: 20140126750Abstract: A controller includes a plurality of channel strips to which are allocated any of a plurality of channels to be handled in a DAW. Each of the channel strips includes a slide operation reception section that receives a slide operation. The slide operation reception sections of the plurality of channel strips are constructed to function as a single slide operation reception unit and to receive a slide operation performed in an arranged direction of the channel strips. Thus, by the slide operation, a user can intuitively and collectively change the allocated channels of the strip channels with a feeling as if merely changing (shifting) the allocated channel of a given channel strip to another channel strip.Type: ApplicationFiled: November 8, 2013Publication date: May 8, 2014Applicant: YAMAHA CORPORATIONInventors: Toru KITAYAMA, Tatsuya UMEO, Mitsunori OCHI

Patent number: 8712073Abstract: An apparatus for extracting a signal from convolutive mixtures includes a receiving unit which includes two or more receivers and receives a signal; a transfer function calculation unit which calculates transfer functions for demixing; and a demixing unit which demixes the received signal using the calculated transfer functions. The transfer function is determined such that a signal is extracted from a source closest to the receivers, and is calculated on the basis of a transfer function for a path to each receiver being approximated to a delta function as closer to the source.Type: GrantFiled: December 16, 2011Date of Patent: April 29, 2014Assignee: Korea Advanced Institute of Science and TechnologyInventors: Soo-Young Lee, Jae-Kwon Yoo

Patent number: 8712060Abstract: A method and apparatus for processing an audio signal is disclosed. Herein, the method includes receiving a downmix information having at least two independent objects and a background object downmixed therein; separating the downmix information into a first independent object and a temporary background object using a first enhanced object information; and extracting a second independent object from the temporary background object using a second enhanced object information.Type: GrantFiled: March 17, 2008Date of Patent: April 29, 2014Assignee: LG Electronics Inc.Inventors: Hyeon O Oh, Yang Won Jung

Publication number: 20140112499Abstract: The audio production console includes a touch-sensitive display cradled by a chassis that also includes a console panel and meter bridge. The touch-sensitive display includes an IR sensor perimeter and related circuitry for processing multi-touch events simultaneously and translating those events into parameter controls. The parameter controls are represented digitally on the display in a GUI reminiscent of traditional analog production console layouts. Software tracks movement of the digital parameter controls and works in conjunction with hardware to manipulate production audio as one or more on-screen parameters are adjusted by touching the display.Type: ApplicationFiled: October 23, 2013Publication date: April 24, 2014Applicant: Yellow Matter Entertainment, LLCInventors: Steven Andrew Lintz, Alexander Charles Oana
