20110000372 | Device and method for cleaning a centrifugal separator - A centrifugal separator device for concurrent separation of solid and/or liquid particles suspended in a gaseous media includes a rotor having a multiplicity of sedimentation members and which is mounted rotatably in a surrounding housing. An intake is provided for the gaseous medium to be cleaned, which leads to a central inlet shaft of the rotor. The housing has an outlet for cleaned gas, which has been freed of solid and/or liquid particles on passage through the sedimentation members in the rotor, and an outlet for the solid and/or liquid particles, which have been deposited on the sedimentation members and then transferred to a side wall of the housing by a centrifugal force. A nozzle is arranged upstream of the sedimentation members in order to supply a liquid to the sedimentation members. | 01-06-2011 |

20100223053 | EFFICIENT SPEECH STREAM CONVERSION - Speech frames of a first speech coding scheme are utilized as speech frames of a second speech coding scheme, where the speech coding schemes use similar core compression schemes for the speech frames, preferably bit stream compatible. An occurrence of a state mismatch in an energy parameter between the first speech coding scheme and the second speech coding scheme is identified, preferably either by determining an occurrence of a predetermined speech evolution, such as a speech type transition, e.g. an onset of speech following a period of speech inactivity, or by tentative decoding of the energy parameter in the two encoding schemes followed by a comparison. Subsequently, the energy parameter in at least one frame of the second speech coding scheme following the occurrence of the state mismatch is adjusted. The present invention also presents transcoders and communications systems providing such transcoding functionality. | 09-02-2010 |

20120243702 | METHOD AND ARRANGEMENT FOR PROCESSING OF AUDIO SIGNALS - Method and arrangement in an audio handling entity, for damping of dominant frequencies in a time segment of an audio signal. A time segment of an audio signal is obtained, and an estimate of the spectral density or “spectrum” of the time segment is derived. An approximation of the estimate is derived by smoothing the estimate, and a frequency mask is derived by inverting the approximation. An emphasized damping is assigned to the frequency mask in a predefined frequency range, as compared to the damping outside the predefined frequency range. Frequencies comprised in the audio time segment are then damped based on the frequency mask. The method and arrangement involves no multi-band filtering or selection of attack and release times. | 09-27-2012 |

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 |
20090262947 | Apparatus and Method for Producing 3D Audio in Systems with Closely Spaced Speakers - An audio processing circuit includes a crosstalk cancellation circuit that is advantageously simplified for use in audio devices that have closely-spaced speakers. In particular, crosstalk filtering as implemented in the circuit assumes that the external head-related contralateral filters are time-delayed and attenuated versions of the external, head-related ipsilateral filters. With this assumption, the circuit's crosstalk filtering is configurable for varying audio characteristics, according to a small number of settable parameters. These parameters include configurable first and second attenuation parameters for cross-path signal attenuation, and configurable first and second delay parameters for cross-path delay. Optional sound normalization, if included, uses similar simplified parameterization. Further, in one or more embodiments, the audio processing circuit and method include or are associated with a defined table of parameters that are least-squares optimized solutions. The optimized parameter values provide wider listening sweet spots for a greater variety of listeners. | 10-22-2009 |
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 |
