Two digital data sets are combined by equating a first subset of samples to neighboring samples from a second subset which is interleaved with the first subset of samples where the equated samples of the two digital data sets do not correspond in time, and by subsequently adding corresponding samples from both digital data sets. This results in a third digital data set that allows the unraveling of the two digital data sets. The third digital data set, when combining two digital audio streams into a single digital audio stream, is still a good mono representation of the two combined digital audio streams and can thus be reproduced on regular reproduction equipment, yet the use of a decoder according to the invention allows the unraveling of the two digital data sets from the third digital data set.
A method for combining a first digital data set (20) of samples (A0, A1, A2, A3, A4, A5, A6, A7, A8, A9) with a first size and a second digital data set (30) of samples (B0, B1, B2, B3, B4, B5, B6, B7, B8, B9) with a second size into a third digital data set (40) of samples (C0, C1, C2, C3, C4, C5, C6, C7, C8, C9) with a third size smaller than a sum of the first size and the second size, comprising the steps of:
A non-transitory computer readable media comprising code means for executing the combination a first digital data set having samples with a first size with a second digital data set having samples with a second size to form a third digital data set having samples with a third size which is smaller than the sum of the first and second size, the first digital data set having first and second subsets of samples which are equated to one another, the first and second subsets of samples being interleaved within the first digital data set, the second digital data set having third and fourth subsets of samples which are equated to one another, the third and fourth subsets of samples being interleaved within the second digital data set, the third digital data set having samples created by adding samples of the equated first digital data set, in the time domain, to corresponding samples of the equated second digital set together with embedded first and second seed samples from respective ones of the first and second digital data sets on a computer providing a suitable environment for execution of the code means.
