A recording/editing apparatus is provided with an operation inputting device. A user uses this operation inputting device to input record-reservation information, a delete condition to delete record contents from a storage medium, or the like. Moreover, the recording/editing apparatus can access a server via a communicating device and a network. The server accumulates and saves program-information provided from other users, and supplies information corresponding to the delete condition to the recording/editing apparatus, in accordance with a request of the recording/editing apparatus. The recording/editing apparatus judges whether or not the delete condition is satisfied on the basis of the supplied information, and deletes the record contents from the storage medium if the delete condition is satisfied.

A data management device in a karaoke system which receives a first data file by a receiving unit and is stored in a rewritable memory such as a hard disk. A second data file, recorded on a recording medium such as a CD-ROM, is read out by a reading unit. A file number comparing unit then compares the file numbers of the first and second data file and a file managing unit erases the first data file if the file numbers coincide with each other. In addition, a version comparing unit compares versions of both the first and second data file. If the first data file version is older than the second data file version, then the file managing unit erases the first data file version, so as to ensure that the new version is always used. Furthermore, a detecting unit detects whether data files corresponding to targeted items are recorded in both, the rewritable memory and the recording medium. In the event that data files are recorded in both, the file managing unit erases the data file in the rewritable memory.

Sound field correcting apparatus and method, in which at least two reflected sound generating circuits are cascade connected and output signals of the reflected sound generating circuits are added. A plurality of initial reflected sound signals for an original signal are first generated. Further many reflected sound signals are subsequently generated for the plurality of initial reflected sound signals. Those many reflected sound signals are obtained as reverberation sound portions.
