摘要： An apparatus (100) for determining a converted spatial audio signal, the converted spatial audio signal having an omnidirectional audio component (W' ) and at least one directional audio component, from an input spatial audio signal, the input spatial audio signal having an input audio representation (W) and an input direction of arrival (∅). The apparatus (100) comprises an estimator (110) for estimating a wave representation (W) comprising a wave field measure and a wave direction of arrival measure based on the input audio representation (W) and the input direction of arrival (∅). The apparatus (100) further comprises a processor (120) for processing the wave field measure and the wave direction of arrival measure to obtain the omnidirectional audio component (W ) and the at least one directional component (X; Y; Z).

摘要： An apparatus for generating an audio output signal to simulate a recording of a virtual microphone at a configurable virtual position in an environment includes a sound events position estimator and an information computation module. The former is adapted to estimate a sound source position indicating a position of a sound source in the environment, wherein the sound events position estimator is adapted to estimate the sound source position based on first and second direction information provided by first and second real spatial microphones, respectively, located at first and second real microphone positions in the environment, respectively. The information computation module is adapted to generate the audio output signal based on a first recorded audio input signal, on the first real microphone position, on the virtual position of the virtual microphone, and on the sound source position.

摘要： A spatial audio processor for providing spatial parameters based on an acoustic input signal comprises a signal characteristics determiner and a controllable parameter estimator. The signal characteristics determiner is configured to determine a signal characteristic of the acoustic input signal. The controllable parameter estimator for calculating the spatial parameters for the acoustic input signal in accordance with a variable spatial parameter calculation rule is configured to modify the variable spatial parameter calculation rule in accordance with the determined signal characteristic.
