Abstract
A method of processing a signal representing an input sound signal is disclosed. The signal is divided in time into a plurality of signal segments, each having an individual duration of time. The signal segments are processed into an output signal of successive signal segments in such a way that at least one, preferably all, of the signal segments are repeated immediately and successively at least once in the output signal. Each signal segment is established in such a way that the duration of time of a majority, preferably all, of the signal segments is less than 60 ms. Thus, a sound signal can be reduced in speed by doubling the number of short cycles.
