  • Patent number: 8588427
    Abstract: An apparatus for extracting an ambient signal from an input audio signal comprises a gain-value determinator configured to determine a sequence of time-varying ambient signal gain values for a given frequency band of the time-frequency distribution of the input audio signal in dependence on the input audio signal. The apparatus comprises a weighter configured to weight one of the sub-band signals representing the given frequency band of the time-frequency-domain representation with the time-varying gain values, to obtain a weighted sub-band signal. The gain-value determinator is configured to obtain one or more quantitative feature-values describing one or more features of the input audio signal and to provide the gain-value as a function of the one or more quantitative feature values such that the gain values are quantitatively dependent on the quantitative values.

  • Publication number: 20130283829
    Abstract: A method for providing a refrigerant medium having a controlled flow temperature in a secondary cycle (20), wherein the refrigerant medium in the secondary cycle (20) takes up heat from one or more process coolers (22) and then gives off heat to primary water in a primary cycle (10) before it flows back to the process coolers (22), wherein at least two primary heat exchangers (12, 14) are present for cooling the refrigerant medium, in addition a bypass line (26) in the secondary cycle (20) branches off after exit from the process coolers (22) for bypassing the primary heat exchangers (12, 14), and the temperature in the secondary cycle (20) in the flow to the process coolers (22) is controlled via the setting of the bypass stream.
