Abstract: An apparatus for generating one or more audio output channels from one or more audio signals is provided. The apparatus comprises a gain determiner configured to generate or to receive gain information, wherein the gain information indicates for each audio signal of at least one audio signal of the one or more audio signals how to attenuate or how to amplify said audio signal depending on a position associated with said audio signal and a reference position. Moreover, the apparatus comprises a signal generator configured to generate the one or more audio output channels from the one or more audio signals by attenuating or amplifying at least one of the one or more audio signals depending on the gain information.

Abstract: An apparatus for providing a sequence of output gains, wherein the sequence of output gains is suitable for attenuating a background signal of an audio signal is provided. The apparatus comprises a signal characteristics provider configured to receive or to determine signal characteristics information on one or more characteristics of the audio signal, wherein the signal characteristics information depends on the background signal, wherein the signal characteristics information comprises a sequence of input gains which depends on the background signal and on a foreground signal of the audio signal. Moreover, the apparatus comprises a gain sequence generator configured to determine the sequence of output gains depending on the sequence of input gains.

Abstract: According to the disclosure, a sensor assembly, in particular for a guide, is provided, which has a sensor and an analysis device. The analysis device determines a movement profile of the guide component based on a vibration signal detected by the sensor, wherein a part of the movement profile is used for the fatigue detection. Alternatively or additionally, it can be provided that the vibration signal detected by the sensor is filtered or digitally filtered and the or a movement profile of the guide component is determined based on the filtered or digitally filtered signal.
