Patent number: 10602293Abstract: The encoding and decoding of HOA signals using Singular Value Decomposition includes forming based on sound source direction values and an Ambisonics order corresponding ket vectors (|Y(?s)) of spherical harmonics and an encoder mode matrix (?OxS). From the audio input signal (|x(?s)) a singular threshold value (?s) determined. On the encoder mode matrix a Singular Value Decomposition is carried out in order to get related singular values which are compared with the threshold value, leading to a final encoder mode matrix rank (rfine). Based on direction values (?l) of loudspeakers and a decoder Ambisonics order (Nl), corresponding ket vectors (|Y(?l)) and a decoder mode matrix (?OxL) are formed. On the decoder mode matrix a Singular Value Decomposition is carried out, providing a final decoder mode matrix rank (rfind).Type: GrantFiled: March 14, 2019Date of Patent: March 24, 2020Assignee: Dolby International ABInventors: Holger Kropp, Stefan Abeling

Patent number: 10341802Abstract: Currently there is no simple and satisfying way to create 3D audio from existing 2D content. The conversion from 2D to 3D sound should spatially redistribute the sound from existing channels. From a multi-channel 2D audio input signal (x(k)(t)) a 3D sound representation is generated which includes an HOA representation Formula (I) and channel object signals Formula (II) scaled from channels of the 2D audio input signal. Additional signals Formula (III) placed in the 3D space are generated by scaling (21, 222; 41, 422; Formula (IV)) channels from the 2D audio input signal and by decorrelating (24, 25; 44, 45, 451; Formula (V)) a scaled version of a mix of channels from the 2D audio input signal, whereby spatial positions for the additional signals are predetermined. The additional signals Formula (III) are converted (27; 47) to a HOA representation Formula (I).Type: GrantFiled: November 11, 2016Date of Patent: July 2, 2019Assignee: Dolby Laboratories Licensing CorporationInventors: Alexander Krueger, Johannes Boehm, Sven Kordon, Xiaoming Chen, Stefan Abeling, Florian Keiler, Holger Kropp

Patent number: 9628921Abstract: An optical microphone comprises a light source configured to emit a light beam and an acoustic sensor configured to reflect the light beam. The acoustic sensor includes single-wall nanotubes and deflects in response to pressure waves. An optional reflector of the optical microphone is configured to re-reflect the light beam from the acoustic sensor. A detector is configured to detect the light beam from the acoustic sensor or the reflector, and thus measures the pressure waves.Type: GrantFiled: June 15, 2015Date of Patent: April 18, 2017Assignee: THOMSON LICENSINGInventors: Holger Kropp, Jens Spille, Malte Borsum
