摘要： An audio signal processor for providing ambient signal channels on the basis of an input audio signal, is configured to extract an ambient signal on the basis of the input audio signal. The signal processor is configured to distribute the ambient signal to a plurality of ambient signal channels in dependence on positions or directions of sound sources within the input audio signal, wherein a number of ambient signal channels is larger than a number of channels of the input audio signal.

摘要： An apparatus for processing an audio input signal comprising one or more audio channels to obtain an audio output signal according to an embodiment is provided. The apparatus comprises a reverberation gain determiner (110) configured to determine reverberation gain information depending on the audio input signal. Moreover, the apparatus comprises a signal processor (120) configured to obtain the audio output signal depending on the reverberation gain information by adding artificial reverberation to the audio input signal or to a preprocessed audio signal, which depends on the audio input signal.

摘要： An apparatus for measuring a plurality of loudspeakers arranged at different positions comprises: a test signal generator (10) for generating a test signal for a loudspeaker; a microphone device (12) being configured for receiving a plurality of different sound signals in response to one or more loudspeaker signals emitted by a loudspeaker of the plurality of loudspeakers in response to the test signal; a controller (14) for controlling emissions of the loudspeaker signals by the plurality of loudspeakers and for handling the plurality of different sound signals so that a set of sound signals recorded by the microphone device is associated with each loudspeaker of the plurality of loudspeakers in response to the test signal; and an evaluator (16) for evaluating the set of sound signals for each loudspeaker to determine at least one loudspeaker characteristic for each loudspeaker and for indicating a loudspeaker state using the at least one loudspeaker characteristic for the loudspeaker. This scheme allows an automatic, efficient and accurate measurement of loudspeakers arranged in a three-dimensional configuration.
