Title: System for transmitting and receiving sound code
Inventor: NAKAJIMA MASANOBU
IPC: G10L19/00
Filed: 1987-10-15
Abstract: PURPOSE:To properly execute a linear forecast processing even if the sound of a high input level is inputted by correcting the operated result up to an intermediate point and data that are not yet operated and resuming the operation when an over-flow is generated during the operation. CONSTITUTION:When the over-flow is generated in a hardware while the operation of the linear forecast processing is executed on the transmitting side, to the result which is operated until the time, and the data which are operating subjects and not operated yet, a constant is multiplied and the operation is resumed from the interrupting point. Then, at a receiving time, to a reproducing sound reproduced by a signal processing, the result multiplied by the inverse of the above mentioned constant is outputted. Thus, even if sound of high input level which is over the operating capacity of a computer is inputted, the forecast processing can be properly executed.
