摘要：Provided is an encoding apparatus. A threshold value calculating unit ()calculates a threshold value from a statistical amount of conversion factors of anextended band. A representative conversion factor extracting unit () uses the calculatedthreshold value to extract conversion factors having large amplitudes. If the number of

extracted conversion factors does not reach a specified number, the threshold valuecalculating unit () determines, in accordance with a lacking number of conversion factors,an amount by which the threshold value should be lowered, and modifies the thresholdvalue accordingly. The representative conversion factor extracting unit () uses thethreshold value, which has been modified, to extract conversion factors. Such thresholdvalue modification by the threshold value difference calculating unit () and such

conversion factor extraction by the representative conversion factor extracting unit () arerepeated until the number of extracted conversion factors reaches the specified number.
