Publication number: 20180279062Abstract: An audio surround processing system receives an audio source signal having at least two audio channels and generates a number of additional surround sound signals in which an amount of artificially generated ambient energy is controlled in real-time at least in part by an estimate of ambient energy that is contained in the audio source signal. The system may divide the audio source signal into two sets of components; a first set of components and a second set of components. The first set of components may be in a range of frequency that is less than a range of frequency of the second set of components. An ambience estimate control coefficient may be generated using the transformed first set of components. An overall gain may be determined using the ambience estimate control coefficient. The overall gain may be used in generation of the additional surround sound signals.Type: ApplicationFiled: May 25, 2018Publication date: September 27, 2018Inventors: Ulrich Horbach, Anandhi Ramesh

Patent number: 9847096Abstract: An audio playback device may drive an audio reproduction device at a volume level. An audio capture device may convert sound waves into audio input. An environment sensing device may detect, based on the audio input, environmental conditions surrounding a user of the audio playback device, the environmental conditions including a loudness estimation indicative of a level of background noise included in the audio input and an audio content classification indicative of presence of speech in the audio input. The environment sensing device may also determine, according to the environmental conditions, a playback action to alter the volume level being provided by the audio playback device, and provide, to the audio playback device, an adjustment to the volume level in accordance with the playback action.Type: GrantFiled: February 20, 2015Date of Patent: December 19, 2017Assignee: Harman International Industries, IncorporatedInventors: Srikanth Konjeti, Anandhi Ramesh

Patent number: 9535455Abstract: A portable media enhancement device for use with a mobile device for processing one or more media files is provided. The mobile device is located separately from the portable media enhancement device. The portable media enhancement device comprises a docking connection input used to communicate with the mobile device and at least one control module. The control module is configured to establish a connection with the mobile device via the docking connection input and to receive one or more media files from the mobile device. The control module is further configured to decode the one or more media files and post process the one or more media files. The control module is further configured to transmit the decoded and processed media files to the mobile device.Type: GrantFiled: April 11, 2014Date of Patent: January 3, 2017Assignee: Harman International Industries, Inc.Inventors: Ravi Lakkundi, Anandhi Ramesh

Patent number: 9426568Abstract: A computer-program product embodied in a non-transitory computer read-able medium that is programmed for transmitting audio data to at least one output for audio playback. The computer-program product comprises instructions for receiving at least one of a digital image of a target source using a camera, and distance and angle information of the target source entered at a user interface. The computer-program product comprises instructions for generating one or more first coordinates based on the at least one of the digital image and the distance and angle information. The computer-program product comprises instructions for adjusting a sensitivity of a first microphone based on the one or more first coordinates. The computer-program product comprises instructions for receiving audio data from the target source in response to adjusting the sensitivity of the first microphone and transmitting the audio data to one or more outputs for audio playback.Type: GrantFiled: April 15, 2014Date of Patent: August 23, 2016Assignee: Harman International Industries, LLCInventors: Ravi Lakkundi, Srikanth Konjeti, Anandhi Ramesh
