Abstract:
A reproducing apparatus, comprising:reproducing means for reproducing highly efficiently encoded data from a record medium, the highly effectively encoded data being composed of spectrum data and scale factor data; memory means for temporarily storing the highly efficiently encoded data reproduced by said reproducing means; operating means for causing the scale factor data of the highly efficiently encoded data stored in said memory means to be changed; memory controlling means for controlling a write address pointer and a read address pointer so that the highly effectively encoded data is intermittently written to said memory means at a first speed and highly efficiently encoded data is read from said memory means at a second speed, the second speed being lower than the first speed; determining means for determining whether or not the address of the highly efficiently encoded data whose scale factor data is changed corresponding to said operating means and stored in said memory means is apart from the read address by a predetermined distance; and controlling means for canceling the change of the scale factor data when the address of the highly efficiently encoded data whose scale factor data is changed corresponding to said operating means and stored in said memory means is not apart from the read address by the predetermined distance as the determined result of said determining means.
