摘要： It is inter alia disclosed to check whether an audio signal captured from an environment of the apparatus comprises arriving sound from an audio source of interest, and to provide a direction identifier being indicative on the direction of the arriving sound from the audio source of interest via a user interface when said check yields a positive result.

摘要： The invention relates to audio conferencing. Audio signals are received and transformed to a spectrum, and then modified by mel-frequency scaling and logarithmic scaling before a second-order transform. The obtained coefficients can be further processed before carrying out the similarity comparison between signals. Voice activity detection and other information like mute signalling can be used in the formation of the similarity information. The resulting similarity information can be used to form groups, and the resulting groups can be analyzed topologically. The similarity information can then be used to form a control signal for audio conferencing, e.g. to control an audio conference so that a signal of a co-located audio source is removed.

摘要： A method includes determining, using signals captured from two or more microphones (1A) configured to detect an acoustic signal from one or more sound sources, one or more prominent sound sources based on the one or more sound sources (1C-1D). The method further includes determining one or more directions relative to a position of one or more of the two or more microphones for the one or more prominent sound sources (1B-1D). The method includes modifying one or more user interface elements displayed on a user interface of a display to provide an indication at least in part of the one or more directions, relative to position of at least one microphone, of the one or more prominent sound sources (1G).

摘要： A method comprising: receiving at least one audio channel signal; receiving at least one user interface input; generating a visualisation of the at least one audio channel signal dependent on the at least one user interface input; and rendering the at least one audio channel signal to generate a rendered audio signal dependent on the at least one user interface input wherein the rendered audio channel signal is substantially synchronised with the visualisation of the at least one audio channel signal.
