| 20080273708 | Early Reflection Method for Enhanced Externalization - Scenes having at least one simulated sound source and simulated sound-reflecting objects are simulated by processing a direct-sound signal with at least one head-related transfer-function, thereby generating a simulated direct-sound signal, and generating simulated early-reflection signals from the simulated direct-sound signal, including simulating early reflections having incidence angles different from the incidence angle of the direct-sound signal. Externalization of the simulated sound source is enhanced. | 11-06-2008 |

| 20100142413 | Media Stream Setup in a Group Communication System - A basic idea for efficient media communication between two nodes in a group communication system is to set up a number, N, of parallel, separate media streams of the same media type in a given direction between the nodes, where N is equal to or greater than 2. Before setting up the media streams, the actual number of media streams is negotiated (S | 06-10-2010 |
| 20100215164 | METHODS AND ARRANGEMENTS FOR GROUP SOUND TELECOMMUNICATION - A method of audio scene management in a teleconference or other group sound telecommunication is presented, in which teleconference at least a first transmitting party, a second transmitting party and a receiving party participates. The method comprises receiving of signals representing sound of the first transmitting party and sound of the second transmitting party. The method further comprises obtaining of measures of sound activity for the first and second transmitting parties, respectively and selecting a first angle and/or a second angle based on the obtained measures of sound activity. The method further comprises processing of the received signals into processed signals such that sound from the first transmitting party is experienced by the receiving party as emanating from the first angle while sound from the second transmitting party is experienced as emanating from the second angle, with respect to the receiving party. Finally signals representing the processed signals are outputted. | 08-26-2010 |
| 20100260344 | Method and Arrangement for Echo Cancellation of Voice Signals - A method and arrangement for cancelling echoes in a communication terminal ( | 10-14-2010 |
| 20100274561 | Noise Suppression Method and Apparatus - The present invention relates to a method and apparatus of a digital filter for noise suppression of a signal representing an acoustic recording. The method comprises determining a desired frequency response (H(ω)) of the digital filter; and generating a noise suppression filter based on the desired frequency response. The desired frequency response is determined in a manner so that the desired frequency response does not exceed a maximum level, wherein the maximum level is determined in response to the signal to be filtered. | 10-28-2010 |
| 20110137646 | Noise Suppression Method and Apparatus - The present invention relates to a method and a filter design apparatus for designing a digital filter arrangement for noise suppression of a signal representing an acoustic recording. The method comprises determining a desired frequency response of the digital filter arrangement. The method is characterised by including a combination of a high pass filter and a noise suppression filter in the filter arrangement. The combination of the high pass filter and the noise suppression filter is selected based on the determined desired frequency response. | 06-09-2011 |
