Publication number: 20210152939Abstract: Embodiments may relate to an audio system for playback of an audio signal, for example in a motor vehicle. The audio system may include a virtualization speaker located in a position that would be in front of a listener of the audio system. The audio system may further include a user speaker located in a position that would be behind a listener of the audio system. In some embodiments the virtualization speaker may be configured to play a virtualization audio signal while the user speakers are configured to play an audio signal which at least partially overlaps the virtualization audio signal. In some embodiments the virtualization audio signal may be at a different volume or a different frequency range than the audio signal. Other embodiments may be described or claimed.Type: ApplicationFiled: November 19, 2019Publication date: May 20, 2021Applicant: Analog Devices, Inc.Inventors: Boris LERNER, Robert ADAMS, Christopher HANNA, Kenneth MALSKY, Philip Gregory GEERLING, Alan Peter NORTON, Andre VAN SCHYNDEL

Patent number: 8416019Abstract: A digitally-controlled analog gain circuit supports a plurality of gain settings in which gain changes are made from a first setting to a new setting in response to a clocking signal. Large changes in gain are interpolated in small gain steps or increments. The clocking signal can be generated by an oscillator, or as a sequence of pulses output by a zero crossing detector. The gain circuit can apply positive gain to the signal. Alternatively, the gain circuit can apply a negative gain (attenuation) to the signal. The clocking signal can be provided in a pseudo-randomized manner to minimize unwanted signal effects such as discernable sound transients.Type: GrantFiled: August 16, 2010Date of Patent: April 9, 2013Assignee: THAT CorporationInventors: Robert W. Moses, Leslie B. Tyler, Christopher Hanna
