Abstract
An audio signal generator for generating an audio signal (20) having a selected length (14) comprises a database interface (10) for accessing a database (12) having information on a plurality of different predefined sequences of audio samples, the information for a sequence comprising an order (12c) of audio samples in the sequence and a duration (12b) of the sequence. The audio signal generator additionally comprises a processor (14) for constructing the audio signal (20) by serially connecting a plurality of sequences using the information on the duration (12b) of each sequence in accordance with the construction algorithm to obtain the audio signal (20) having the selected length (15).
