Publication number: 20230072391Abstract: An audio rendering system includes a processor that combines audio input signals with personalized spatial audio transfer functions having room responses. The personalized spatial audio transfer functions are selected from a database having a plurality of candidate transfer functions derived from in-ear microphone measurements for a plurality of individuals. Alternatively, the personalized transfer functions are derived from actual in-ear measurements of the listener. A room modification module allows the user to modify the personalized spatial audio transfer functions to substitute a different room or to modify the characteristics of the selected room without requiring additional in ear measurements. The module segments the selected transfer function into regions including one or more of direct; head and torso influenced; early reflection, and late reverberation regions. Extraction and modification operations are performed on one or more of the regions to alter the perceived sound.Type: ApplicationFiled: November 14, 2022Publication date: March 9, 2023Applicant: Creative Technology LtdInventors: Teck Chee LEE, Christopher HUMMERSONE, Mark Anthony DAVIES, Toh Onn Desmond HII

Patent number: 11601775Abstract: A method is provided for generating a personalized Head Related Transfer Function (HRTF). The method can include capturing an image of an ear using a portable device, auto-scaling the captured image to determine physical geometries of the ear and obtaining a personalized HRTF based on the determined physical geometries of the ear. In addition, a system and a method in association with the system are also provided for customizing audio experience. Customization of audio experience can be based on derivation of at least one customized audio response characteristic which can be applied to an audio device used by a person. Finally, methods and systems are provided for rendering audio over headphones with head tracking enabled by, for example, exploiting efficiencies in creating databases and filters for use in filtering 3D audio sources for more realistic audio rendering and also allowing greater head movement to enhance the spatial audio perception.Type: GrantFiled: September 29, 2020Date of Patent: March 7, 2023Assignee: CREATIVE TECHNOLOGY LTDInventors: Teck Chee Lee, Desmond Hii

Publication number: 20230006785Abstract: Systems and techniques are provided to transmit data over a digital interface between a sender and a receiver. The digital interface is configured for transmitting a primary type of data as opposed to a secondary type of data. Nevertheless, systems and techniques are provided where the secondary type of data can be transmitted in the digital interface. As such, the primary and/or secondary types of data are transmitted from the sender to the receiver via the digital interface. The primary and secondary types of data may be different and/or unrelated and could be any type of data including, but not limited to, audio data, general data, and bulk data. Yet, the received primary and secondary types of data are still useful after the transmission.Type: ApplicationFiled: November 20, 2020Publication date: January 5, 2023Applicant: Creative Technology LtdInventors: Teck Chee LEE, Toh Onn Desmond HII, Jenny Afliccion ESTEBAN

Publication number: 20230007433Abstract: A headphone for spatial audio rendering includes a first database having an impulse response pair corresponding to a reference speaker location. A head sensor provides head orientation information to a second database having rotation filters, the filters corresponding to different azimuth and elevation positions relative to the reference speaker location. A digital signal processor combines the rotation filters with the impulse response pair to generate an output binaural audio signal to transducers of the headphone. Efficiencies in creating impulse response or HRTF databases are achieved by sampling the impulse response less frequently than in conventional methods. This sampling at coarser intervals reduces the number of data measurements required to generate a spherical grid and reduces the time involved in capturing the impulse responses. Impulse responses for data points falling between the sampled data points are generated by interpolating in the frequency domain.Type: ApplicationFiled: September 12, 2022Publication date: January 5, 2023Applicant: Creative Technology LtdInventors: Teck Chee LEE, Geith Mark Benjamin LESLIE, Mark Anthony DAVIES, Edwin TOMBOZA, Toh Onn Desmond HII

Publication number: 20220394418Abstract: An audio rendering system includes a processor that combines audio input signals with personalized spatial audio transfer functions preferably including room responses. The personalized spatial audio transfer functions are selected from a database having a plurality of candidate transfer function datasets derived from in-ear microphone measurements for a plurality of individuals. Alternatively, the personalized transfer function datasets are derived from actual in-ear measurements of the listener. Foreground and background positions are designated and matched with transfer function pairs from the selected dataset for the foreground and background direction and distance. Two channels of input audio such as voice and music are processed. When a voice communication such as a phone call is accepted the music being rendered is moved from a foreground to a background channel corresponding to a background spatial audio position using the personalized transfer functions.Type: ApplicationFiled: August 15, 2022Publication date: December 8, 2022Applicant: Creative Technology LtdInventors: Wong Hoo SIM, Teck Chee LEE

Patent number: 11221820Abstract: Techniques are provided to transform external sound from an external position of an external audio space to an internal position of an internal audio space where the external sound would be heard naturally. The techniques involve capturing the external sound with a microphone and processing the captured external sound to appear as if it was captured at the internal position of the internal audio space, which may correspond to an output of a driver or a user's eardrum. Then the processed captured external sound may be conditioned for the individual user or further combined with conditioned audio content to create an augmented audio experience for the user. Any combination of the techniques can be implemented in real time.Type: GrantFiled: March 12, 2020Date of Patent: January 11, 2022Assignee: Creative Technology LtdInventors: Teck Chee Lee, Toh Onn Desmond Hii
