摘要：Information is encoded into a code with a smaller number of bits. An encodingapparatus encodes an acoustic time series signal such that the acoustic time series signalis split into band signals in predetermined bands and gain adjustment is made on theband signals, at a gain control position by a gain control amount, for each of as many

positions as indicated by a gain control number. Although the gain control number cantake any one of values from 0 to 7, it has a high probability of taking a particular value (0,for example). The gain control number is encoded such that a code with a small numberof bits is assigned to the gain control number equal to a value having a high-occurrenceprobability. The encoding is also applied to a voice recording apparatus.
