Abstract  Abstract

Mixer (600) for mixing a plurality of input frames, each input frame being a spectral representation of a corresponding time domain frame and each input frame being provided with the plurality of input frames from a different source, comprising: an entropy decoder (610) configured to decode by entropy the plurality of input frames; a climber (630) configured to scale the plurality of input frames decoded by entropy in the frequency domain and configured to obtain a plurality of frames scaled in the frequency domain, each frame scaled to an input frame decoded by entropy; an adder (640) configured to add scaled frames in the frequency domain to generate an aggregate frame in the frequency domain; and an entropy encoder (660) configured to entropy encode the aggregate frame to obtain a mixed frame, the mixer (600) being configured to generate the mixed frame based on the plurality of input frames, where each of the frames Input of the plurality of input frames is generated by an encoder (400) comprising a bank (200, 800) of analysis filters to filter a plurality of input frames in the time domain, comprising an input frame several ordered input samples, comprising a window former (110) configured to generate a plurality of window frames, a window frame comprising a plurality of window samples, the window former (110) being configured to process the plurality of input frames overlapping using a sample value in advance, the window former being configured to generate two window frames consecutively based on two input frames, for each input frame, weighing at least a plurality of input samples of the respective input frame with a window function, with the two input frames overlapped in several ordered input samples which is larger that half of the number of input samples ordered from the input frames and the value in advance of the sample is less than the number of input samples ordered from an input frame divided by 2; and a time / frequency converter (120) configured to provide an output frame comprising a number of output values, an output frame being a spectral representation of a window frame.
