Abstract

A method for recording a digitized audio signal and a telephone answering machine in which this method can be advantageously employed. A digitized audio signal is written in during a first time segment, and the written-in data are then stored in memory in a storage medium for digital data. After the first time segment, the writing in of the digital input signal is continued. The data now written in are compressed by a predetermined compression algorithm in accordance with a predetermined data compression rate. Finally, the thus-compressed data are stored in the storage medium for digital data. With the method, especially economical utilization of a limited memory storage volume is possible.
