摘要： An apparatus for capturing audio information from a target location is provided. The apparatus comprises a first beamformer (110) being arranged in a recording environment and having a first recording characteristic, a second beamformer (120) being arranged in the recording environment and having a second recording characteristic and a signal generator (130). The first beamformer (110) is configured for recording a first beamformer audio signal and the second beamformer is configured for recording a second beamformer audio signal when the first beamformer (110) and the second beamformer (120) are directed towards the target location with respect to the first and the second recording characteristic. The first beamformer (110) and the second beamformer (120) are arranged such that a first virtual straight line, being defined to pass through the first beamformer (110) and the target location, and a second virtual straight line, being defined to pass through the second beamformer (120) and the target location, are not parallel with respect to each other. The signal generator (130) is configured to generate an audio output signal based on the first beamformer audio signal and on the second beamformer audio signal so that the audio output signal reflects relatively more audio information from the target location compared to the audio information from the target location in the first and the second beamformer audio signal.

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 is provided. The apparatus comprises a sound events position estimator and an information computation module (120). The sound events position estimator (110) is adapted to estimate a sound source position indicating a position of a sound source in the environment, wherein the sound events position estimator (110) is adapted to estimate the sound source position based on a first direction information provided by a first real spatial microphone being located at a first real microphone position in the environment, and based on a second direction information provided by a second real spatial microphone being located at a second real microphone position in the environment. The information computation module (120) is adapted to generate the audio output signal based on a first recorded audio input signal, based on the first real microphone position, based on the virtual position of the virtual microphone, and based on the sound source position.

摘要： An apparatus for generating an audio output signal having two or more audio output channels from an audio input signal having two or more audio input channels is provided. The apparatus comprises a provider (110) and a signal processor (120). The provider (110) is adapted to provide first covariance properties of the audio input signal. The signal processor (120) is adapted to generate the audio output signal by applying a mixing rule on at least two of the two or more audio input channels. The signal processor (120) is configured to determine the mixing rule based on the first covariance properties of the audio input signal and based on second covariance properties of the audio output signal, the second covariance properties being different from the first covariance properties.
