Description

  The present invention relates to a karaoke recording / editing apparatus for reconfiguring music by cutting and editing a portion of a multi-take singing voice recording file, and more particularly to a user interface that can be edited based on lyrics characters.

  Many music data editing software are known. Waveform editing software is common, but it is a tool for displaying audio data captured in a personal computer as a waveform, cutting noise, applying effects, and cutting and pasting files. While checking the waveform visually, the editing position of the music data can be specified and the music data can be edited.

In karaoke, a service capable of creating a CD-ROM or MD in which a user's singing voice is recorded together with accompaniment music is well known. In connection with such a karaoke recording system, for example, a number of techniques such as Japanese Patent No. 3515069 and Japanese Patent No. 3522215 have been disclosed. Users of this service want to keep a little workable at hand, and re-record it many times until they are satisfied with being professional.
Japanese Patent No. 3515069 Japanese Patent No. 3522215

  In karaoke recording, it is very difficult to achieve a satisfactory finish from the beginning to the end of a song with a single singing. For this part, the first singing was good, but for this part, the third singing was good.

  Therefore, the present inventor wanted to partially adopt and edit a multi-take karaoke recording so that it can be made into one piece. For this purpose, editing work for cutting and pasting audio data is essential. However, people who use karaoke recordings generally do not have musical expertise. There are not a few people who cannot read the score, and most of them have never seen the waveform of the voice data. Although it is generally known, editing work by a user interface such as waveform editing software is not suitable for a scene where a karaoke user enjoys editing in a limited time. Therefore, the present invention has been created for the purpose of providing a user interface that allows anyone who uses karaoke to easily edit karaoke recordings.

This invention is specified by the following items (1) to (9).
(1) It is a karaoke recording / editing device provided with storage means, display means, operation input means, and control means. (2) The storage means includes karaoke data of the music to be edited and a plurality of takes of the music. (3) The karaoke data includes accompaniment music data and lyrics display data having time information linked to the time series of the accompaniment music data. (4) The singing voice recording file includes accompaniment music data. Time information associated with the time series of
(5) The display means displays the lyrics under the control of the control means. (6) The operation input means can identify any character in the displayed lyrics and can identify the take. (7) The control means performs the first specifying process and the second specifying process when cutting and pasting a portion of the multi-take singing voice recording file to reconstruct the music. (8) The first specifying process is: Lyrics are displayed on the display means based on the lyrics display data, and the position on the time axis of the accompaniment music data is specified by the lyric character specified by the operation input means. (9) The second specifying process is performed by the operation input means. Determining the position on the time axis of the singing voice recording file of the specified take from the position on the time axis of the accompaniment music data specified in the first specifying process

  According to the karaoke recording / editing apparatus of the present invention, it is possible to easily edit recording data while viewing the lyrics display even if there is no music expertise such as a score or a sound waveform. For this reason, it is possible to easily create the best karaoke recording piece by connecting some good points from recordings of multiple takes. Therefore, since the recording time can be rationalized, more people can have an opportunity to enjoy the karaoke recording service.

=== Basic configuration and functions of karaoke recording and editing device ===
FIG. 1 shows an outline of an electrical system configuration of a karaoke recording / editing apparatus according to an embodiment of the present invention.

  The main computer 1 controls the entire karaoke recording / editing apparatus. The hard disk device 2 stores various information such as a program of the main computer 1, a karaoke database, and a video database. The operation / display panel unit 3 can input various types of information by the user, and can display various types of information for the user. The communication processing unit 7 communicates with an external karaoke server or a member information server via a communication line. In addition, communication with the portable computer 14 is possible via the wireless port 13.

  The portable computer 14 can exchange various information interactively with users participating in the karaoke gathering, and communicates with the main computer 1 via the wireless port 13. The portable computer 14 is a palmtop type or laptop type personal computer, and a liquid crystal display with a transparent touch panel is largely laid out on the front as a user interface. Is programmed to exchange information.

  For the requested music designated by the user using the operation / display panel 3 or the portable computer 14, the karaoke data of the corresponding music is extracted from the karaoke database and transferred to the performance processing unit 8. The performance processing unit 8 performs stereo accompaniment music based on the karaoke data under the control of the main computer 1, amplifies the music signal with the mixing amplifier 9, and emits the sound through the speaker.

=== Composition of karaoke data ===
The karaoke data of each song is an organization of song numbers, MIDI performance data, recording data, and lyrics subtitle data. As is well known, MIDI performance data specifies each of various types of karaoke sound sources as one instrument, and specifies the sound generation / mute timing, pitch, volume, etc. of each performance sound to be generated by each instrument. Yes. It also specifies the tempo and beat of the entire song. At the time of performance processing, a timing clock signal is generated based on this tempo, the sounding / mute timing of each musical instrument performance sound is determined, and performance sounds are generated in time series. Thereby, each musical instrument performance sound can be synchronized.

  As is well known, the lyrics subtitle data specifies a plurality of appropriately divided lyrics character string blocks, data that defines the display layout of each lyrics character string block, and the display / erase timing of each block. It consists of data and data that specifies the timing for changing the color of the character string in each block in accordance with the progress of music. The timing information is determined by the timing clock signal at the time of performance processing, and each block is displayed in synchronization with the performance sound, and the lyric characters to be sung are displayed in different colors.

  In the present embodiment, the karaoke data includes lyric display data. As will be described later, the lyric display data is data for displaying lyric characters on the liquid crystal display of the portable computer 14 and has a configuration similar to the lyric subtitle data. The display layout of each lyric character string block only needs to be translated on the screen. Therefore, it is sufficient to add a predetermined value to the display layout defining data of the lyrics subtitle data.

  For each lyric character, utterance timing information to be sung is attached as time information in the progress of music. The utterance timing information is data defined similarly to the color change timing information of the lyrics subtitle data. That is, the utterance start timing for each lyric character is defined in the same manner as the color change start timing. The utterance end timing for each character is defined in the same manner as the color change end timing. Therefore, the lyric display data can appropriately use the specified value of the lyrics subtitle data.

=== Structure of singing voice recording file ===
The mixing amplifier 9 of the karaoke recording / editing apparatus of the present embodiment incorporates an A / D conversion circuit and can perform singing voice recording processing. For example, when the singing voice recording process is executed by inputting a “singing voice recording” menu from the top menu of the portable computer 14 illustrated in FIG. 2, the accompaniment music and the singing voice to be output to the speaker according to the instruction from the main computer 1. Are converted into digital signals and sequentially transferred to the main computer 1. In the singing voice recording process, the main computer 1 sequentially stores digital audio signals from the mixing amplifier 9 in a predetermined data format in the RAM. When the recording of one song is completed, the main computer 1 composes a singing voice recording file including singing voice recording data, tempo information at the time of performance (recording), and time information from the start of the performance of the singing voice, and a necessary identifier is set. And stored in the hard disk device 2.

  As time information from the start of performance of the singing voice, singing voice recording data and timing information about an appropriate point are associated with each other. This timing information is time information in units of timing clock signals similar to the timing information of the karaoke data described above. Timing clock signals are counted during the singing voice recording process, and timing information based on the count number (clock number) is stored in association with the position of the singing voice recording data in a timely manner. Thereby, the correspondence between the position on the time axis of the singing voice recording data and the position on the time axis of the karaoke data can be understood.

  In this embodiment, when recording a singing voice, a multi-take singing voice recording file is created for the singing of the same music by the same singer. Therefore, when creating a singing voice recording file, each singing voice recording file is identified by giving an identification code combining a singing ID determined by the singer and the music number and a take number.

  Of course, singing voice recording data can also be played back with a karaoke recording and editing device. Based on an instruction from the main computer 1, reproduction processing is performed by a D / A conversion circuit built in the mixing amplifier 9, and sound is emitted from a speaker.

=== Editing process of singing voice recording file ===
In this embodiment, the user can use the portable computer 14 to edit a multi-take singing voice recording file for the same song. When the user inputs “Recording Edit” in the top menu (see FIG. 2) and designates the editing process of the singing voice recording file, the portable computer 14 designates the singer and the song number (that is, designates the singing ID). Transition to the screen (see FIG. 3A). The portable computer 14 performs data communication with the main computer 1 as appropriate, and obtains a plurality of singing voice recording files having the same singing ID and different take numbers for the combination of the singer and the tune number designated here (singing ID). At the same time, the list is displayed so as to be selectable (see FIG. 3B). For example, a list of take numbers can be selected and designated. Then, when any take number is instructed to be selected and a reproduction instruction is input, the singing voice recording file of the take is reproduced and emitted.

  Furthermore, the lyrics of the music can be displayed on the same screen of the portable computer 14. The lyric characters are displayed based on the lyric display data. It communicates with the main computer 1 and is used by obtaining it from the portable computer 14. When an operation for designating a lyric character is performed on the screen, the utterance timing information (speech start timing / utterance end timing) associated with the lyric character in the lyric display data is notified. Yes.

  At the start of the editing process, the first block of lyrics is displayed on the screen. It is also possible to display instructions before and after the displayed block by inputting an instruction to turn the page as appropriate. While any one of the singing voice recording files is being reproduced, the lyrics block is displayed in synchronization with the recording / reproducing sound in the same way as during karaoke performance while referring to the timing information of the singing voice recording file.

  The user can check the portion of each take with good performance while appropriately reproducing the singing voice recording file of each take. Then, it is a feature of the present invention that portions with good workmanship from each take can be collected and re-edited into a song recording file for one song.

  For example, when the first take is good for the first several blocks, the first take is selected from the take number list display, and the start character (from the displayed lyric block to which the first take is to be adopted ( In this case, the beginning of the lyrics) and the end character to be adopted are designated and input. In this case, an operation input to turn the page appropriately is performed, the block before and after the displayed lyrics block is displayed, and an instruction input is made for a portion to be specified. As the start character, it is preferable to automatically specify the first character of the section where the adopted take is not yet determined, and to specify only the end character by the user.

  The portable computer 14 receives notification of the utterance timing information corresponding to each of the designated start character and end character, and from the first take singing voice recording data, the section corresponding to the utterance timing information, that is, the start of utterance of the start character Data of the section (referred to as the first section) from the timing to the end timing of the utterance of the end character is extracted and stored (referred to as the first edit data).

  For the second section following the first section, for example, if the user wants to adopt the fifth take, the user selects and instructs the fifth take from the take number list display, and the section to be adopted from the displayed lyrics block. Specify and enter the start and end characters. In this case, the next character after the end character of the first section is automatically input as the start character. As in the case of the first section, the portable computer 14 is notified of the utterance timing information corresponding to each of the designated start character and end character, and corresponds to the utterance timing information from the singing voice recording data of the fifth take. The section data is taken out and stored so as to be connected to the first edit data.

  When the user repeats the above operation and designates a take to be adopted until the end of the singing section, the editing process is terminated. Then, an appropriate identification code (for example, a singing ID and an editing number. The editing number may be a number for identifying editing data, or may be an identification number for a plurality of editing data). .) Is added to form an edit file and transferred to the main computer 1.

  It is also possible to edit the edit file again. FIG. 4 illustrates a user interface including a case where the edit file is re-edited. At the start of the singing voice recording editing, the created editing file is also obtained together with the singing voice recording files of a plurality of takes corresponding to the same singing ID. A list of edit numbers is displayed together with a list of take numbers so as to be selectable (see FIG. 4B). Thereafter, the same operation as described above is performed to re-edit.

  In particular, when re-editing an edit file, it is better to adopt only a partial section from another take so that it can be overwritten. For example, as illustrated in FIG. 4A, a re-editing mode is provided in the editing process, and when the re-editing mode is instructed and input, an edit file to be edited is designated and a take number is designated. The lyric character of the section to be adopted is displayed, the section is designated and input, and the edited data of the section is overwritten and saved.

=== Other Embodiments ===
The system configuration of the present invention is not limited to the above embodiment. The karaoke recording / editing device and the portable computer 14 may be integrated into a hardware device.

The singing voice recording data may be configured to record the singing voice and the accompaniment music on separate tracks. In this case, the user inputs his / her singing voice toward the microphone while listening to the accompaniment music with the headphones connected to the karaoke recording / editing apparatus when recording the singing voice. In this way, each take contains only a singing voice. In the editing process, an edit track is created by cutting and pasting the data of each track. Naturally, only the singing voice is included in this edit track. The edit file includes an accompaniment music track, an edit track, and timing information. In this way, it is possible to prevent the accompaniment music from being interrupted or overlapping due to an error that may occur in the editing process.
In this case, the accompaniment music track of the singing voice recording data may be recorded only once for take 1, or may be overwritten at the time of recording each take.

  In addition, a combination of singing voice recording data without accompaniment music and accompaniment music in karaoke data format can be handled as a work. In this case, when the work is reproduced by the karaoke recording / editing apparatus or another karaoke apparatus, the singing voice and the accompaniment music are reproduced by referring to the accompanying timing information and synchronizing with the performance processing of the accompaniment music.

  Furthermore, if it is assumed that accompaniment music in the karaoke data format is combined when reproducing a work, it is possible not to include accompaniment music in the work.
