20080232603 | SYSTEM FOR MODIFYING AN ACOUSTIC SPACE WITH AUDIO SOURCE CONTENT - An audio signal processing system is configured to separate an audio signal into a dry signal component and one or more reverberant signal components. The dry signal component and the reverberant signal components can be separately modified and then recombined to form a processed audio signal. Alternatively, the dry signal component may be combined with an artificial reverberation component to form the processed audio signal. Modification of the reverberation signal component and generation of the artificial reverberation component may be performed in order to modify the acoustic characteristics of an acoustic space in which the audio signal is driving loudspeakers. The audio signal may be a pre-recorded audio signal or a live audio signal generated inside or outside the acoustic space. | 09-25-2008 |
20110081024 | SYSTEM FOR SPATIAL EXTRACTION OF AUDIO SIGNALS - A sound processing system receives an audio input signal that includes at least two different input channels of audio content. The sound processing system dissects the audio input signal to separate sources of audible sound included in the audio input signal into sound source vectors. Separation of the sources of audible sound into sound source vectors may be based on a perceived location of each of the sources of audible sound within a listener perceived sound stage. The sound source vectors may represent spatial slices across the listener perceived sound stage that may be individually and independently processed with the sound processing system. Following processing, the sound source vectors may be selectively assembled to form an audio output signal having output channels used to drive respective loudspeakers. Since the sources of audible sound are separated and independent, the audible sound sources may be included on any one or more of the output channels. | 04-07-2011 |
20110081032 | MULTICHANNEL AUDIO SYSTEM HAVING AUDIO CHANNEL COMPENSATION - A multichannel compensating audio system includes first and second compensation channels to psychoacoustically minimize deviations in a target response, to psychoacoustically move the physical position of a speaker and/or to psychoacoustically provide a substantially equal magnitude of sound from a plurality of speakers in a plurality of different listening positions. The first compensation channel may include a series connected delay circuit, a level adjuster circuit and a frequency equalizer circuit that generates a first compensated audio signal from a first audio signal. The second compensation channel may include a series connected delay circuit, a level adjuster circuit and a frequency equalizer circuit that generates a second compensated audio signal from a second audio signal. A first summing circuit is configured to receive at least the first audio signal and the second compensated audio signal and generate a first output signal for provision to a first speaker. A second summing circuit is configured to receive the second audio signal and the first compensated audio signal and generate a second output signal for provision to a second speaker. The first and second output signals may be output by the first and second speakers into a listening space and are acoustically perceived by a listener. | 04-07-2011 |

Modification of the reverberation signal component and generation of the artificial reverberation component may be performed in order to modify the acoustic characteristics of an acoustic space in which the audio signal is driving loudspeakers. The audio signal may be a pre-recorded audio signal or a live audio signal generated inside or outside the acoustic space. | 11-01-2012 |
20140140537 | AUDIO LOUDNESS CONTROL SYSTEM - An audio loudness control system includes a loudness adjuster module configured to adjust a level of an audio signal based on parameters associated with the audio signal. The parameters may include identification of a source of the audio signal. The parameters associated with the audio signal may be provided to the loudness adjuster in a message associated with the audio signal. The audio loudness control system may also include a database in communication with the loudness adjuster module. The loudness adjuster module may be configured to extract loudness related settings or parameters from the database that are associated with a source of the audio signal. | 05-22-2014 |
20140149126 | SYSTEM FOR PERCEIVED ENHANCEMENT AND RESTORATION OF COMPRESSED AUDIO SIGNALS - A system for processing compressed audio includes a signal enhancer module configured to generate one or more signal treatments. The one or more signal treatments may be generated by the signal enhancer module based on analysis of the incoming audio signal. Alternatively, or in addition, characteristics of the incoming audio signal may be provided to the signal enhancer module for use in generating the one or more signal treatments. The one or more signal treatments may be added to the audio signals. | 05-29-2014 |
