A device provides a first data signal that indicates an activity of at least one muscle of a patient that is relevant for an inspiratory breathing effort and a second data signal that indicates an activity of at least one muscle of the patient that is relevant for an expiratory breathing effort. The data signals are generated from electromyography (EMG) signals detected by surface electromyography sensors. A computer is configured to determine breathing phase information on the basis of a breathing signal and to check at least one of the electromyography signals or at least one of the separated signals for detectability of a heart signal component and further to assign the signals to an inspiratory breathing activity as well as to an expiratory breathing activity of the patient as a function of the breathing phase information.

Device and process for providing data signals indicating muscle activities that are relevant for inspiratory as well as expiratory breathing efforts of a patient

The invention refers to a system for handling digital content including an input interface, a calculator, and an output interface. The input interface receives digital content and includes a plurality of input channels. At least one input channel receives digital content from a sensor or a group of sensors belonging to a recording session. The calculator provides output digital content by adapting received digital content to a reproduction session in which the output digital content is to be reproduced. The output interface outputs the output digital content and includes a plurality of output channels, wherein at least one output channel outputs the output digital content to an actuator or a group of actuators belonging to the reproduction session. Further, the input interface, the calculator, and the output interface are connected with each other via a network. The input interface is configured to receive digital content via by Ni input channels, where the number Ni is based on a user interaction, and/or the output interface is configured to output the output digital content via by No output channels, where the number No is based on a user interaction. The invention further refers to a corresponding method.

An audio signal decorrelator for deriving an output audio signal from an input audio signal has a frequency analyzer for extracting from the input audio signal a first partial signal descriptive of an audio content in a first audio frequency range and a second partial signal descriptive of an audio content in a second audio frequency range having higher frequencies compared to the second audio frequency range. A partial signal modifier modifies the first and second partial signals, to obtain first and second processed partial signals, so that a modulation amplitude of a time variant phase shift or time variant delay applied to the first partial signal is higher than that applied to the second partial signal, or for modifying only the first partial signal. A signal combiner combines the first and second processed partial signals, or combines the first processed partial signal and the second partial signal, to obtain an output audio signal.
