Subband encoding and decoding system for data compression and decompression

摘要: A subband encoding and a decoding system are provided. The measures signal levels of signals to determine scale factors obtain factor information produces bit allocation based on the information, flag indicating fact that has changed from one frame earlier, updated which earlier. re-quantizes using provide re-quantized output constructs as an encoded made up signals, information. number subbands be is determined by upper limit frequency audible band. This results in decrease operation load systems.
