Abstract

PURPOSE:To reduce the troublesome operations fro confirming the contents and rerecording the sound, etc., on the title sound recorder by performing the verification, editing and rerecording on signals recorded in a temporary storage area and inputting only a confirmed signal into the sound recorder. CONSTITUTION:A voice inputted from a microphone 1 is temporarily stored into a temporary storage device 2 to be reproducibly confirmed. When its vocalization contents are no problem, the voice is recorded as it is into the sound recorder 3. When the vocalization contents are wrong or added with noise, an edit is carried out if the edit is possible, and if not possible, the rerecording is carried out. In this case, its waveform is confirmed by a display 5 or its position is specified from an instruction inputting device 6. The voice confirmed on completion of editing is recorded in the sound recorder 3.

Description

[Detailed description of the invention] Industrial applications The present invention relates to a recording device.

2. Description of the Related Art Conventional recording devices generally have a signal input means and a recording means directly connected. FIG. 3 is a diagram showing an example of a conventional recording device. 1 is a microphone, 3 is a recording device, and 4 is a speaker.

Recording devices include open decks, cassette decks,
Although a disk device or the like is conceivable, an open deck is used in both the conventional example and the embodiment. Voices spoken into the microphone are recorded directly onto tape on the oven deck. The audio stored on the tape is played back through the speakers.

Problems to be Solved by the Invention When recording is performed using a recording device having the configuration shown in the conventional example, it is necessary to rewind the tape and listen to it to check whether the content to be recorded has been uttered correctly. Yes. As a result of confirmation,
If the content of the utterance is incorrect or noise (tongue click, sound of microphone being blown, environmental noise, etc.) is added,
I had to rewind the tape and start recording again. In this way, the user has to perform complicated operations. Also, in order to overwrite the tape, the previous recording (
Mistakes may occur, such as leaving part of the recording to be erased, or overwriting and erasing parts of the recording that do not need to be erased.

The present invention has been made in view of this point, and has a temporary storage means for signals, and before recording the input signal in the recording device, stores the input signal in the temporary storage area, verifies and edits the input signal, and checks the verified By recording only the signal on a recording device,
This is an attempt to solve the above problems.

Means for Solving the Problems The present invention provides a signal input means for inputting a signal to be recorded, and a temporary storage means for temporarily storing the signal input from the signal input means. This is a recording device characterized by comprising an editing device that performs processing on a signal stored in a storage device, and a recording device that records the signal obtained by the editing device.

Effect of the present invention With the above-described configuration, the signals recorded in the temporary storage area are verified, edited, and re-recorded, and only the verified signals are input to the recording device. We aim to reduce complicated work such as checking the content and re-recording.

Embodiment FIG. 1 is a diagram showing the configuration of a recording device according to an embodiment of the present invention. 1 is a microphone; 2 is a temporary storage means for temporarily storing the audio input from the microphone; 3 is a recording device, which is an oven deck in this embodiment; 4 is a speaker for storing audio. The content is reproduced. A display device 5 displays the data stored in the temporary memory. A device 6 is an input device for editing commands for inputting editing commands and specifying the position of data.

FIG. 2 is a block diagram showing details of the temporary storage device. 2a is an audio input end from a microphone, 2b is an audio input end from a recording device, and 2c is a microphone/recording device changeover switch. In addition, 2d is the audio output end to the speaker, 2
e is an audio output terminal to the recording device, and 2f is a speaker/recording device changeover switch. 2g is a cutoff of 8k
This is a low-pass filter that cuts high-frequency components for Hz A/D and D/A. 2h is an A/D, 21 is a D/A, and in this example, the sampling frequency is 20kHz, 16
Performs A/D conversion and D/A conversion with bit precision. Reference numeral 21 denotes a recording/editing unit that stores and executes various commands related to recording/playback and editing. , 2j temporarily store the digitized audio signal in a temporary storage area. 21 is an output terminal to the display device, and 2m is an input terminal of the command input device.

An example of the operation of this recording device is as follows. The audio input from the microphone 1 is temporarily stored in the temporary storage device 2,
Playback is confirmed. If there is no problem with the uttered content, it is recorded as is in the recording device 3. If the utterance is incorrect or noise is added, edit it if possible, or record it again if it is not possible. Editing refers to deleting a part of the audio data stored in the temporary storage area or adding a silent part. At that time,
Check the waveform on the display device and specify the position using the command input device. Once the editing has been completed and the audio has been confirmed, it is recorded on a recording device.

As described above, according to this embodiment, by providing a temporary storage device and performing audio confirmation, re-recording 1 editing, etc. on the temporary storage device, the above-mentioned work on the recording device is reduced, and the recording processing simplification and reduce mistakes.

DETAILED DESCRIPTION OF THE INVENTION As described in detail, according to the present invention, a temporary storage device is provided, and by checking, re-recording, editing, etc. the signal to be recorded on the temporary storage device, the above-mentioned information on the recording device is It can reduce work, simplify recording processing, and reduce mistakes, and its practical value is great.
