Provided are a method which permits complete training data and data with added errors, and enables the early and accurate discovery of errors in facilities such as a plant, and a system thereof. Audio streaming comprises the digitally phase locked playback of a real time n-bit digital audio stream, where n may be a large number, e. Mixing parameters may be recalled from stored program control or modulated in real-time by arbitrary control signals, including envelope generators, low-frequency oscillators, and those derived from an original input signal, and specifically including the amplitude of an original input signal. Values for a received digital image are transformed for each image pixel or clusters of pixels based on the calculated set of transformations. A second control unit is included and adapted to limit, in respect of the duration of its effect, a rejection of the user identity module expressed by the locally available wireless data networks in logging on to the wireless data network by suitable control of the first control unit in the further course of the log-on process by bypassing communicated information about the rejection.
