Method for digitally recording an analog audio signal with automatic indexing

摘要

A method for digitally recording an analog audio signal with automatic indexing, having the following steps: (a) an analog audio signal containing audio information and signal pauses is read in, (b) the analog audio signal is converted into digital audio data comprising audio information data and signal pause duration data, (c) the audio information data are stored as information data blocks and the signal pause duration data are stored as signal pause data blocks in a memory, (d) the stored data blocks are read sequentially and an index table is produced, any succession of information data blocks which is not interrupted by a signal pause with a predetermined duration being detected as one cohesive audio information data sequence whose start and end are stored in the index table.
