Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

An audio editing apparatus for an additional communication system according to the present invention includes a voice recorder 10, a personal computer 20, and an additional communication system 30 as shown in FIG.

The service contents to be provided by the voice recorder 10 are edited and recorded by the service provider on the personal computer 20.

In the voice editor 21 of the personal computer 20, a sound card 21a, a voice S / W editor 21b, and a data storage 21c are provided. The sound card 21a is provided from the voice recorder 10. The recorded voice is retrieved and applied to the voice S / W editing unit 21b.

The voice S / W editing section includes a recording section 21b-1, a voice PCM file editing section 21b-2, and a PCM / ADPCM converting section 21b-3. The recording section 21b-1 includes a sound card 21a. The voice inputted through the N-T is converted into a voice PCM file and applied to the data storage 21c.

The voice PCM file editing unit 21b-2 applies the voice PCM file from the data storage unit 21c, plays back, edits it, and applies it to the data storage unit 21c.

The PCM / ADPCM conversion unit 21b-3 compresses and converts the voice PCM file applied from the data storage unit 21c into an ADPCM file and stores it in the data storage unit 21c again. The data storage unit 21c stores the stored voice. The ADPCM file is applied to the additional communication system 30 through the LAN.

In the additional communication system 30, the voice ADPCM file applied through the LAN is stored in the data storage unit 31, and then voice service is performed by the voice service system 32.

The operation of the present invention configured as described above will be described in detail with reference to FIG. 2 as follows.

First, a data storage 21c of the personal computer 10 selects whether a previously recorded voice PCM file is to be recalled, whether a new recording is made to create a PCM file, skips, or ends (step S1). . When selecting to load, the previously stored PCM recording file is loaded and opened (step S2). When selecting the recording, after opening the file, the pre-recorded voice is input to the PC 20 through the sound card 21a, the recording unit 21b-1 is converted into a PCM file, and the voice file is stored and opened. (Step S3). The file opened afterwards is selected through the voice file editing unit 21b-2 to play back the voice, to edit the PCM voice file, to save or to remove the offset (step S4). If the audio playback is selected in step S4, the audio file is played and listened to and returned to step S1 (step S5). If the audio editing is selected in step S4, the PCM audio file is edited and returned to the step S1 (step S5). S6) When the offset is selected in step S4, when recording in step S3, due to the electrical problem with the peripheral device due to the characteristics of the sound card, silence is not '0' and + α or -α is recorded as silence. Since it is not clean, it is adjusted to '0', and after performing the offset elimination process that subtracts or adds an offset of + α or -α value, returns to the step S1 (step S7), and stores it in the step S4. If you select to save the played voice file in PCM method or ADPCM method (Step S7), if you choose to save the voice file in PCM method, the PCM method is selected. If the user selects to save as an ADPCM file (step S8), the PCM / ADPCM conversion unit 21b-3 converts and stores the ADPCM method and returns to step S1 (step S8). From step S5 to step S8 The user can select at any time, and when the operation is finished, the process returns to the step S1 and when one wants to continue working on the file, the process returns to the step S4 to work on the already loaded file, and when the other file is desired, the step Return to S1 to load or select a recording to work with, or exit when you choose to exit.

In this case, by converting several PCM files into ADPCM format files at once, voice editing work is streamlined, and voice editing is done on the PC so that it does not operate the telephone network and additional communication system, thereby economically improving power consumption.

As described above, the present invention efficiently processes voice editing and management operations without operating a telephone network and an additional communication system through a PC voice editor, and enables short time voice editing and multiple PCM files to be used as ADPCM format files at once.
