摘要： A method for encoding and decoding data streams representing sounds in digital form inside a synthesizer, comprising the steps of: dividing data streams into a plurality of categories according to the different values assumed by the characteristic parameters that define the data streams, each category being adapted to group the streams that are similar one another in terms of the value assumed by the selected parameter; using a plurality of encoding algorithms to compress the data streams to be stored in the synthesizer and a plurality of corresponding decoding algorithms to decompress the compressed data streams in order to reproduce the original sounds, each algorithm being particularly suitable to process the data streams that belong to at least one of the categories; and selecting, for each data stream, the encoding algorithm and the corresponding decoding algorithm that allow the smallest difference between the data stream and, respectively, the compressed and decompressed data streams.
