Publication number: 20200152210Abstract: A method and device are disclosed for determining an inter-channel time difference of a multi-channel audio signal having at least two channels. A determination is made at a number of consecutive time instances, inter-channel correlation based on a cross-correlation function involving at least two different channels of the multi-channel audio signal. Each value of the inter-channel correlation is associated with a corresponding value of the inter-channel time difference. An adaptive inter-channel correlation threshold is adaptively determined based on adaptive smoothing of the inter-channel correlation in time. A current value of the inter-channel correlation is then evaluated in relation to the adaptive inter-channel correlation threshold to determine whether the corresponding current value of the inter-channel time difference is relevant. Based on the result of this evaluation, an updated value of the inter-channel time difference is determined.Type: ApplicationFiled: January 15, 2020Publication date: May 14, 2020Inventors: Manuel BRIAND, Tomas JANSSON TOFTGÅRD

Patent number: 10311881Abstract: Disclosed methods and apparatuses determine an inter-channel time difference of a multi-channel audio signal by determining a set of local maxima of a cross-correlation function involving at least two different channels of the multi-channel audio signal, for positive and negative time-lags and associating each local maximum with a corresponding time-lag. Local maximums for the positive and negative time-lags are selected from the set as respective positive and negative time-lag inter-channel correlation candidates. Processing also includes evaluating whether there is an energy-dominant channel, when the absolute value of a difference in amplitude between the inter-channel correlation candidates is smaller than a first threshold, and, when there is an energy-dominant-channel, identifying the sign of the inter-channel time difference and extracting a current value of the inter-channel time difference based on the time-lag corresponding to the positive or negative time-lag inter-channel correlation candidate.Type: GrantFiled: April 12, 2018Date of Patent: June 4, 2019Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Manuel Briand, Tomas Jansson Toftgård
