Summary:The invention relates in general to a method for combining frequency domain encoded signals from at least two signal sources. To allow combining signals without decoding the signals entirely, the invention provides decoding the encoded signals obtaining quantized spectral components, inverse quantizing the quantized spectral component of the decoded signals obtaining window sequences, and combining the at least inverse quantized signals obtaining a combined signal.
