Title:
【発明の名称】改善された符号器を有するオーディオ伝送システム
Document Type and Number:
Japanese Patent JP2003502703
Kind Code:
A
Abstract:
In a transmission system an audio signal is encoded by an encoder (4), and transmitted by transmit means (6) via a medium (8) to a receiver (10). In the audio encoder (4) audio segments are represented by a plurality of sinusoids each having its own frequency and amplitude. In order to link the audio segments together, it is advantageous to link sinusoids from subsequent segments. The problem in linking the segments is to find which sinusoids should be linked. In the prior art, the components were linked on basis of their frequency differences (closest frequency neighbor criterion). According to the present invention, the linking is done by using an analysis-by-synthesis method. Preferably a preselection is made in order to reduce the complexity of the search. This preselection can be based on the closest frequency neighbor criterion.
