Abstract: A method for generating and providing an audio signal, including receiving a first audio signal via an external microphone of a headphone or earphone, and receiving a second audio signal via a wireless interface. The first audio signal includes a portion reproduced via loudspeakers. The second audio signal corresponds to the portion reproduced via loudspeakers and is received before the corresponding portion of the first audio signal. A propagation time difference is determined between the first audio signal and the second audio signal. The second audio signal is modified by adaptive filtering and temporal shifting such that the propagation time difference between the first and second modified audio signal is substantially compensated. The adaptive filtering models an acoustic transmission of the first audio signal and a modified second audio signal is obtained. The modified second audio signal is inverted, then it is provided via the headphone or earphone.

Abstract: There is provided a control system (1) comprising an earphone (2) and a processing device (3). The control system (1) has a processing device (3) for the evaluation of head movement information and/or head position information. In that case the processing device is adapted to output at least one control signal dependent on the evaluation, wherein the earphone has a sensor device (9a, 9b, 9c) for detecting the movement information and/or position information and a transmitting device (10) for transmitting the movement information and/or the position information to the processing device.

Abstract: A microphone system is provided. The microphone system comprises at least one hand-held microphone and a base station. Audio signals detected by the hand-held microphone are forwarded to the base station. The hand-held microphone comprises a motion detection unit for detecting a motion or a gesture of a hand-held microphone. A control signal generating unit generates control signals based on the detected motion or gesture of the hand-held microphone. The hand-held microphone is adapted to forward the detected motion or gesture or the control signals to the base station. The output audio signal of the hand-held microphone can be manipulated based on the control signals. The hand-held microphone comprises an activation unit for activating or deactivating the motion detection unit or for activating or deactivating the transmission of the control signals.

Abstract: There is provided a transmitter for a wireless audio transmission system comprising at least one analog/digital converter unit for analog/digital conversion of the analog audio signals to be transmitted, at least one digital signal processing unit with a compressing/encoding device for compressing and encoding the digitized signal to be transmitted, a digital/analog converter unit for digital/analog conversion of the digital output signals of the digital signal processing unit into analog signals, and a transmitting unit for wirelessly transmitting the output signals of the digital/analog converter unit.

Abstract: A compressor device for a compander system has a level detecting/control device and a pre-emphasis device for carrying out an adaptive pre-emphasis filtering. The invention is also directed to an expander device for a compander system with a level detecting/control device and a de-emphasis device for carrying out an adaptive de-emphasis filtering.
