Abstract: The invention relates to a method for broadcasting a spatialized audio stream to terminals of spectators attending a sports event. The method comprises the acquisition of a plurality of audio streams constituting a soundscape. The soundscape is analyzed by a server in order for the sound spatialization of the audio streams and of the playback thereof on terminals, depending both on the localization of the audio flows and also the position of the spectators.

Abstract: The invention relates to a method for broadcasting a spatialized audio stream to terminals (TERM) of spectators attending a sports event. The method comprises the acquisition of a plurality of audio streams constituting a soundscape (SS). The soundscape (SS) is analyzed by a server (SERV) in order for the sound spatialization of the audio streams and of the playback thereof on terminals (TERM), depending both on the localization of the audio flows and also the position of the spectators.

Abstract: The invention relates to data processing for sound playing on a sound playing device (DIS), headset or ear bud type, portable by a user in an environment (ENV). The device comprises at least one speaker (HP), at least one microphone (MIC), and a connection to a processing circuit comprising: An input interface (IN) for receiving signals coming at least from the microphone; A processing unit (PROC, MEM) for reading at least one audio content to play on the speaker; and An output interface (OUT) for delivering at least the audio signals to be played by the speaker. The processing unit is arranged for: a) Analyzing the signals coming from the microphone for identifying sounds coming from the environment and corresponding to predetermined classes of target sounds; b) Selecting at least one identified sound, according to a user preference criterion; and c) Building said audio signals to be played by the speaker, by a selected mixing of the audio content and the selected sound.

Abstract: A method for processing an input signal having an audio component is described. The method includes obtaining a set of time parameters from a time frequency transformation of the audio component of the input signal, the audio component being a mixture of audio signals comprising at least one first audio signal of a first audio source; determining at least one motion feature of the first audio source from a visual sequence corresponding to the first audio signal; obtaining a weight vector of the set of time parameters based on the motion feature; and determining a time frequency transformation of the first audio signal based on the weight vector.
