Claim Text:
1. A signal processor for providing a processed version of an input signal in dependence on the input signal, the signal processor comprising: a windower, configured to window a portion of the input signal, or of a pre-processed version thereof, in dependence on a signal processing window described by signal processing window values for a plurality of window value index values in order to acquire the processed version of the input signal; and a window provider for providing signal processing window values for a plurality of window value index values in dependence on one or more window shape parameters, wherein the window provider is configured to evaluate a sine function for a plurality of argument values associated with the window value index values, to acquire the signal processing window values, wherein the window provider is configured to compute a weighted sum of a linear term, which is linearly dependent on the window value index values, and function values of one or more shaping functions, which one or more shaping functions map window value index values onto corresponding function values and which one or more shaping functions are point-symmetric with respect to a center of a window slope, to acquire the argument values; wherein the window provider is configured to compute the weighted sum in dependence on the one or more window shape parameters, such that the window provider is configured to provide a plurality of different sets of signal processing window values w wherein the signal processor is a media signal encoder; wherein the windower is configured to window a portion of a media signal, or a pre-processed version thereof, in dependence on the signal processing window, to acquire a windowed portion of the media signal; wherein the signal processor is configured to transform the windowed portion of the media signal into a frequency domain; and wherein the signal processor is implemented using a hardware apparatus, a computer, or a combination of a hardware apparatus and a computer.
