Abstract
A recording and reproducing apparatus for recording and reproducing sound using a semiconductor memory as a recording medium, the apparatus including index recording means for storing an index having retrieval information for retrieving an arbitrary position of recorded sound and positional information for indicating a memory address to be retrieved by the retrieval information; and retrieving and reproducing means for retrieving the index containing a specified retrieval information to reproduce the sound from the memory address indicated by the positional information of the index.
Claims13
An apparatus for recording and reproducing sound, comprising:
- a random access semiconductor memory for storing recorded sounds;
- means for recording sounds and storing the recorded sounds in random access fashion in the semiconductor memory;
- means for storing index information in the semiconductor memory, each index including an address of a corresponding portion of recorded sound stored in the semiconductor memory and at least one of a plurality of index codes for marking selected portions of recorded sound;
- means for retrieving a selected portion of stored sound from the semiconductor memory in random access fashion based on the index corresponding to the selected portion;
- and
- means for reproducing the selected portion of sound retrieved by the means for retrieving.
A recording and reproducing apparatus comprising:
- means for recording sound;
- a semiconductor memory having a first section for storing recorded sound and a second section for storing index information for identifying portions of recorded sound;
- means for extracting characteristics of the portions of recorded sound;
- means for storing a sorting code in the semiconductor memory as part of the index information based on the extracted characteristics for portions of recorded sound;
- means for retrieving from the semiconductor memory and reproducing portions of the recorded sound using corresponding index information.
