PURPOSE: To provide a voice editing technique capable of monitoring an output value of a Codec previous to recording, setting an input level in an optimum value by a comparison result with a prescribed value and reducing a recorded data amount in accordance with the variation of the number of quantization bits of the sampling data in a system coding a voice and storing the data in a computer. CONSTITUTION: This device is a voice editing device constituted of a CPU, a memory, a voice source, an A/D converter, a Codec interface, a disk interface, a disk, a speaker and a D/A converter, etc. After a level prescribed value and a monitoring time are set first of all, the digital data are fetched, and the addition of the data and the counting of the number of data are performed for a fixed time (201-204). Then, a mean of input values is calculated after the prescribed time is over, and the mean value is compared with the prescribed value, and when the mean value is larger, an input level is set in lower, and on the other hand, when the mean value is smaller, the input level is set in higher. |
