Patent number: 11163524Abstract: When the volume is adjusted in a multi-speaker system, it is desirable that one speaker does not change volume disproportionately with respect to another speaker. A method is presented for adjusting a volume level of one or more speakers. Each speaker can have a non-standardized relationship between logical volume level that is input to the speaker and sound pressure level that is produced by the speaker. A selected volume level, corresponding to a sound pressure level, can be received via a user interface. A stored lookup table can be accessed to convert the sound pressure level to a first product-specific logical volume level for each speaker. The stored lookup table can tabulate the non-standardized relationship between logical volume level and sound pressure level for each speaker. Data corresponding to the first product-specific logical volume level can be transmitted to each speaker.Type: GrantFiled: September 17, 2020Date of Patent: November 2, 2021Assignee: DTS, Inc.Inventor: Dannie Lau

Patent number: 10897667Abstract: A user device can be used to correct for a latency of an audio chain, which extends inclusively between an input and a speaker. The user device can communicate an indication to the speaker to play a sound at a first time, and record a second time at which a microphone on the user device detects the sound. The user device can compare the first and second times to determine a latency of the audio chain. The user device can communicate adjustment data corresponding to the determined latency to a component in the audio chain. The component can use the adjustment data to correct for the determined latency. In some examples, the user device can display instructions to position the user device a specified distance from the speaker, and can account for a time-of-flight of sound to propagate along the specified distance.Type: GrantFiled: July 18, 2019Date of Patent: January 19, 2021Assignee: DTS, Inc.Inventor: Dannie Lau

Patent number: 10694288Abstract: A user device can be used to correct for a latency of a speaker. The user device can communicate an indication to the speaker to play a sound at a first time. The user device can record a second time at which a microphone on the user device detects the sound. The first and second times can be synchronized to a clock of a computer network. The user device can compare the first and second times to determine a latency of the speaker. The user device can communicate adjustment data corresponding to the determined latency to the speaker. The speaker can use the adjustment data to correct for the determined latency. In some examples, the user device can display instructions to position the user device a specified distance from the speaker, and can account for a time-of-flight of sound to propagate along the specified distance.Type: GrantFiled: May 8, 2019Date of Patent: June 23, 2020Assignee: DTS, Inc.Inventor: Dannie Lau

Publication number: 20200014969Abstract: Media is selected for video playback through a first device and audio playback through one or more separate devices connected through a wireless network. Different techniques for synchronizing the audio and video can be selected based on one or more factors to improve media playback. One aspect features a method and associated user interfaces for selecting to listen to audio through headphones using a user interface on a mobile device. The audio played through the headphones is synchronized to the video being displayed using techniques and systems described herein.Type: ApplicationFiled: July 12, 2019Publication date: January 9, 2020Inventors: Dannie Lau, Darren Kelly O'Brien, Sangyoun Lee
