Patent number: 10242683Abstract: The invention relates to a method for mixing a plurality of audio streams coded according to a frequency sub-band coding, comprising the steps for decoding (E201) a part of the coded streams over at least a first frequency sub-band, for summing (E202) the streams thus decoded so as to form at least a first mixed stream. The method is such that it comprises the steps for detection (E203), over at least a second frequency sub-band different from the at least first sub-band, of the presence of a predetermined frequency band in the plurality of coded audio streams and for summing (E205) the decoded audio streams (E204) for which the presence of the predetermined frequency band has been detected, over said at least a second sub-band, so as to form at least a second mixed stream. The invention also relates to a mixing device implementing the method described and may be integrated into a conference bridge, a communications terminal or a communications gateway.Type: GrantFiled: March 24, 2014Date of Patent: March 26, 2019Assignee: OrangeInventors: Arnault Nagle, Claude Lamblin, Balazs Kovesi

Patent number: 9984698Abstract: The invention relates to a method for combining a plurality of audio streams encoded by frequency sub-band encoding, comprising the following steps: decoding (E301) a portion of the encoded streams over at least one frequency sub-band; combining (E302) the streams thus encoded to form a mixed stream; selecting (E303), from among the plurality of encoded audio streams, at least one encoded replication stream, over at least one frequency sub-band that is different from that of the decoding step. The method is such that the selection of the at least one encoded replication stream is carried out according to a criterion which takes into consideration the presence of a predetermined frequency band in the encoded stream (E304). The invention also relates to a device which implements the described method and can be integrated into a conference bridge, a communication terminal or a communication gateway.Type: GrantFiled: March 24, 2014Date of Patent: May 29, 2018Assignee: OrangeInventors: Claude Lamblin, Balazs Kovesi, Arnault Nagle

Patent number: 9928852Abstract: A method is provided for detecting a predetermined frequency band in an audio data signal which has previously been coded according to a succession of data blocks, among which at least certain blocks contain respectively at least one set of spectral parameters representing a linear prediction filter. Such a method of detection implements, for a current block among the at least certain blocks and for which at least a plurality of spectral parameters of the set have been previously decoded, acts of: determining, among the plurality of previously decoded spectral parameters, the index of the first spectral parameter closest to a threshold frequency; calculating at least one criterion on the basis of the determined index; and deciding whether the predetermined frequency band is detected in the current block, as a function of the criterion calculated.Type: GrantFiled: December 10, 2015Date of Patent: March 27, 2018Assignee: ORANGEInventors: Arnault Nagle, Claude Lamblin

Patent number: 9451094Abstract: Disclosed are hybrid conference bridges capable of selectively operating in a replicating mode or a mixing mode based on the number of terminals in an audio conference capable of supporting the replicating mode. A disclosed conference bridge connects a plurality of terminals in an audio conference and includes a replicating-mode operating module, a mixer-mode operating module, and a management module to activate at least one of the operating modules depending on the number of terminals having sufficient capabilities to support the replicating mode.Type: GrantFiled: December 5, 2007Date of Patent: September 20, 2016Assignee: OrangeInventors: Arnault Nagle, Aurélien Sollaud
