Abstract

PURPOSE:To edit music to fall within a specific time range and to eliminate an undesirable program from an editing result by possessing a function for editing order of music to be reproduced within a specified time and moreover eliminating discretionary music from an editing object at the time of editing with the above function. CONSTITUTION:A memory for storing read-in data and subcoding data of a CD via a signal processing part 2 is incorporated into a microcomputer 3, and the order of music to be reproduced in order to fall within a time mange specified by a display/operation part 5 based on the stored data in this memory and to be capable of eliminating discretionary music specified by the display/ operation part 5 from the editing object. By this method, a reproducing program can be edited to suit a recordable time of a cassette tape, while an undesirable program cannot be entered into the editing result.

The order of the songs to be played is displayed on the display/operation section 5 described later.
It has an editing function that allows editing to fit within the time specified by , and deletes any song specified by the display/operation section 5 from the editing target.

６は信号処理部２から出力されたオーデイオプタを音楽
信号に変換し出力する出力部である。Reference numeral 6 denotes an output section that converts the audio optic output from the signal processing section 2 into a music signal and outputs it.

つぎに、前記実施例の動作を第２図のフ［］−チャート
を用いて説明する。Next, the operation of the above embodiment will be explained using the flowchart of FIG.

まず、編集動作に入る前に、ＣＤのリードインデータは
マイコン４内の所定のメモリ内に記憶されているものと
し、編集には、このデータを用いる。First, before starting the editing operation, it is assumed that the lead-in data of the CD is stored in a predetermined memory in the microcomputer 4, and this data is used for editing.

インタ゛″Ａ　Ｉ＋をＯにする。When the microcomputer 4 is instructed by the display/operation unit 5 to execute the editing function, in step S1, the microcomputer 4 stores its internal memory (track memory) for storing the track order of the edited results and its total time. Clear the memory (time memory) that stores , and set the track pointer ``''A I+'' used as a pointer to O.

次にステップＳ２において、指定された時間（エデイツ

らない。Next, in step S4, the pointer ゛A'' indicating the track to be processed is updated to indicate the next track, and in step S5, the track indicated by pointer ``A'' is the deleted track imported in step S3. A determination is made as to whether it is different from the track, and the determination result is NO.
If (the track not indicated by "A" and the deleted track are the same), the process returns to step S4 and "'A" is updated, so that the deleted track is not subject to editing.

この編集処理を終了する。If the result of the determination is YES (the track indicated by "A" and the delete track are different), in step S6, the time of track "A" is added to the time memory from the lead-in data in the aforementioned memory, and In step S7, it is determined whether the edit time imported in step $2 described above is smaller than the time in the time memory,
If the result of the determination is No (the edit time is larger than the time in the time memory), in step S8, 1

In step S10, it is determined whether the 11 A H track is the last track in the lead-in data, and if the determination is No<"A" track is not the last track. ), the process returns to step S4 and the determination is YES (
The "A" track is the last track. )If,
This editing process ends.
