摘要： An apparatus for generating one or more audio output channels is provided. The apparatus includes a parameter processor for calculating output channel mixing information and a downmix processor for generating the one or more audio output channels. The downmix processor is configured to receive an audio transport signal including one or more audio transport channels, wherein two or more audio object signals are mixed within the audio transport signal, and wherein the number of the one or more audio transport channels is smaller than the number of the two or more audio object signals. The audio transport signal depends on a first mixing rule and on a second mixing rule. The first mixing rule indicates how to mix the two or more audio object signals to obtain a plurality of premixed channels. Moreover, the second mixing rule indicates how to mix the plurality of premixed channels.

摘要： A plurality of speakers disposed in a front and a rear of a passenger and a controller configured to control a sound field in a vehicle cabin by individually driving the plurality of speakers. The controller is configured, when an operation input for changing an acceleration/deceleration behavior of the vehicle is made, to set a normative acceleration/deceleration depending on the operation input, to detect an actual acceleration/deceleration, and to displace the sound field in the vehicle cabin in the direction of a change in the actual acceleration/deceleration behavior of the vehicle depending on the deviation of the actual acceleration/deceleration relative to the normative acceleration/deceleration. That is, a change of an acceleration/deceleration behavior depending on the operation input is rendered before the change of the actual acceleration/deceleration behavior of the vehicle.

摘要： An apparatus for determining a room dimension estimate comprises a receiver (101) providing an acoustic room response e.g. generated from acoustic measurements. A peak detector (103) detects a set of peaks in the acoustic room response in a frequency interval having an upper frequency of no more than 400 Hz. A store (107) comprises a set of peak profiles with associated room dimension data, and an estimator (105) determines the room dimension estimate from the associated room dimension data and a comparison of the set of peaks to the peak profiles. The estimator may perform the steps of first finding a matching peak profile for the set of peaks from the set of peak profiles; extracting first room dimension data associated with the matching peak profile(s) from the store; and determining the room dimension estimate in response to the first room dimension data. The peak profiles may represent calculated Eigenfrequencies.

摘要： A directivity adjustment device that maintains a constant direct-to-reverberant ratio based on the detected location of a listener in relation to the speaker array is described. The directivity adjustment device may include a distance estimator, a directivity compensator, and an array processor. The distance estimator detects the distance between the speaker array and the listener. Based on this detected distance, the directivity compensator calculates a directivity index form a beam produced by the speaker array that maintains a predefined direct-to-reverberant sound energy ratio. The array processor receives the calculated directivity index and processes each channel of a piece of sound program content to produce a set of audio signals that drive one or more of the transducers in the speaker array to generate a beam pattern with the calculated directivity index.
