Description

  The present invention relates to an archive file creation method, a song data extraction method, an archive file creation apparatus, a program, and a song data extraction apparatus suitable for use in backup and restoration of song data and the like used in a multi-track recorder for audio signals.

  Patent Document 1 discloses a multi-track recorder for audio signals with a built-in hard disk. In this method, an input analog signal is converted into a digital signal and recorded as waveform data on a hard disk, and a plurality of tracks can be simultaneously recorded and reproduced. Here, the entity of the waveform data and the track are different data. First, the substance of the waveform data is stored in a plurality of clusters in the hard disk, and the track indicates these clusters and addresses in the clusters. Therefore, the data amount of the track itself is generally small. Here, when editing such as cut, copy, paste, and move is performed on each track, it is desirable to be able to return to the state before editing as necessary. For this reason, the once created track is stored without being destroyed, and the edited result is additionally recorded as a new track.

  Here, a track or the like constituting one piece of music (song) and a header added to the track are called song management data. A collection of the song management data and waveform data is called song data. A conventional multi-track recorder has a function of backing up song data to a removable medium such as a CD-R. Some multitrack recorders have a pad operator. Relatively short waveform data such as percussion instrument sounds, loop phrases, and sound effects are assigned to the pad operator. Waveform data assigned to such a pad operator is called library data. When executing the backup process once, the user selects an arbitrary plurality of song data and an arbitrary plurality of library data stored in the hard disk, and these selected data are stored in one or more CD-Rs. Etc. can be backed up to disk. Also, arbitrary song data or library data can be restored from a plurality of CD-Rs etc. used for backup. Note that the format of the conventional multi-track recorder such as a CD-R is a unique format different from that for a personal computer.

Japanese Patent Laid-Open No. 2002-124022

  By the way, it is convenient if processing such as reading and updating the song data and library data recorded on the hard disk in the multitrack recorder via a personal computer or the like is possible. In order to realize this, it is preferable to provide a USB storage function to the multi-track recorder and build a file system compatible with the file system of the personal computer. In this file system, it is convenient to configure a song folder for each song data, and to store the song file and the waveform file constituting the song data in the song folder. Similarly, for library data, it is convenient to create a folder for each library and store the library data therein.

  Here, all the song data and the like recorded on the multitrack recorder are backed up to a plurality of CD-Rs via the CD-R drive provided in the multitrack recorder while maintaining the above-described file system. Then, let's assume a process of restoring the song data “sakura” to the multitrack recorder at a later date. All the files that make up the song data “sakura” should be stored in the song folder named “sakura” in the above file system. Therefore, it is checked whether the folder “sakura” is recorded in all CD-Rs. If there is a folder “sakura”, the contents are read and written to the hard disk in the multitrack recorder. For example, the restoration of the song data “sakura” can be completed. Moreover, although it is out of the purpose of backup and restore, for example, a waveform file contained in the folder “sakura” can be read into a personal computer and used as a waveform file for DTM (desktop music) on the personal computer. .

However, since a recording medium such as a CD-R is basically a sequential access recording medium, whether or not the folder “sakura” exists on a certain disk is searched through the entire contents of the CD-R. It is impossible to judge without it. Therefore, in the above restore processing, there is a problem that it takes a very long time to search for a recording medium such as a CD-R.

1． Example data structure
1.1. File Configuration Next, a file configuration in the multitrack recorder of one embodiment of the present invention will be described with reference to FIG. In this embodiment, a plurality of song folders 104 and a plurality of library folders 120 are formed in the root directory 100 of the hard disk. Each song folder 104 is given a folder name having the same name as the song name. For example, if the song name is “sakura”, the folder name of the song folder 104 is “sakura”. One song file 106 is stored in the song folder 104. The name of the song file 106 is obtained by adding the extension “.aws” to the song name, and is “sakura.aws” in the above example. In the song folder 104, an audio folder 113 having a folder name “Audio” and a render folder 115 having a folder name “Render” are formed. The audio folder 113 stores a waveform file group 114 composed of a plurality of waveform files 114-1, 114-2,..., And the render folder 115 stores a plurality of render files 116-1, 116-2,. A render file group 116 is stored. The render file is a waveform file having the same format as the waveform file. These song file 106, waveform file group 114, and render file group 116 constitute song data 102. The extension of each waveform file and render file is “.wav”.

  Similar to the song folder 104, each library folder 120 is given a folder name having the same name as the library name. One library file 126 is stored in the library folder 120. The name of the library file 126 is obtained by adding the extension “.awl” to the library name. An audio folder 123 having a folder name “Audio” is formed in the library folder 120, and a waveform file group 124 including a plurality of waveform files having extensions “.wav” is stored therein. The waveform files belonging to the waveform file group 124 are relatively short waveform files such as percussion instrument sounds, loop phrases, and sound effects. These library file 126 and waveform file group 124 constitute library data 122.

1.2. Details of Song Data 102 Next, the configuration of the song data 102 will be described with reference to FIG. In the song data 102, the audio signal entity is stored in the waveform file group 114. The song file 106 is a file that stores song management data that defines the read position of the waveform file. Each song management data has track data 108-1 to 108-16 that defines the content of a maximum of "16" tracks. Each track data is composed of a maximum of "8" virtual track data 110-1 to 110-8. Here, in each track data, one virtual track that is actually used for recording and reproduction is designated. In other words, when recording or playback is performed on a certain “track”, recording or playback is actually performed on any of the designated “virtual tracks”.

  Here, paying attention to a virtual track, on the time axis of this virtual track, there are sections in which the waveform data of the musical tone exists almost continuously and sections in which the musical tone does not substantially exist. The former section is called “region” and the latter section is called “mute section”. Therefore, in this embodiment, data for specifying the contents of the region is recorded only for each region, and in particular, all sections where no region exists are mute sections. Each virtual track data is composed of one or a plurality of region data 112-1, 112-2,... Defining the contents of this region. In the region data, various timings in the song are defined. In this embodiment, the timing in the region data is represented by “sample points”. Here, “sample point” means “how many sampling cycles have elapsed from the start timing of the song. Furthermore, in the region data, any one of the waveform files 114-1, 114-2, The reproduction start timing and the reproduction time are specified for the reproduction start timing and the reproduction end time, and the reproduction end timing is uniquely specified by the reproduction start timing and the reproduction time. The waveform file is indicated by an upward arrow, and the reproduction end timing is indicated by a downward arrow.

  Next, the render file will be described with reference to FIG. First, each waveform file 114-1, 114-2,... Is stored in the hard disk in units of “cluster”. Since all the contents of these waveform files cannot be read into the RAM in the multitrack recorder, the data contents for each “cluster” are read into the buffer memory when the waveform file is played back. become. Here, as an example, it is assumed that the waveform file 114-1 is stored in the clusters 130-1 to 5 of “5”. The reproduction start timing and the reproduction end timing, that is, the reproduction range of the waveform file are set by the region data 112-1, 112-2,..., As shown by hatching in FIG. There is a case where a very narrow range sandwiching the boundary of 130-2 and 130-3 is selected as the reproduction range.

  Since reading data from the hard disk requires physical movement such as movement of the head and rotation of the disk, such waveform data is simply read from the waveform file 114-1 based on the region data. In this case, the readout operation of the clusters 130-2 and 130-3 cannot follow the reproduction operation of the audio signal, and the audio signal being reproduced is interrupted. Therefore, in the present embodiment, when reproducing a short range of waveform data sandwiching the cluster “2”, the reproduction range of these clusters is collected, and the render file 116-1 constituting one cluster 132 is automatically selected. Created on. Thus, when the render file 116-1 for the waveform file 114-1 is created, when the waveform file 114-1 is designated by the region data 112-1, the render file 116-1 is replaced with the waveform file 114-1. 1 is read. The standard for creating a render file is disclosed in the above-mentioned Patent Document 1 (Japanese Patent Laid-Open No. 2002-122402).

1.3. Library data Library data is a library for designating a reproduction range for the waveform file group 124 and each of the waveform files constituting the waveform file group 124 in the same manner as the region data 112-1, 112-2,. File 126. That is, the library file 126 defines one waveform file and its reproduction range corresponding to each pad. These waveform file groups 124 are extremely short, and real-time characteristics are required in which sound is generated without delay when the user operates the pad. For this reason, the library data is read in advance into the RAM in the multitrack recorder. Thus, even if a narrow range sandwiching the “2” cluster of the hard disk is designated as the playback range related to the library data, no particular problem occurs, so no render file is created.

1.4. Data Structure of Backup File Next, the data structure when backing up song data and library data in the multitrack recorder to a CD-R will be described with reference to FIGS. 4 (a) and 4 (b). In FIG. 4A, it is assumed that a certain song data 102 and a certain library data 122 are selected as backup targets. Here, the song data 102 includes a song file 106 and waveform files 114-1 to 114-4, and the library data 122 includes a library file 126 and waveform files 124-1, 124-2. A column in which these files are arranged in the order to be recorded is called a data column 150. Next, the data string 150 cut into a size that can be recorded on one new recording disc (CD-R or CD-RW set) is called “partial data”. In the example of FIG. 4A, since the recordable size is up to the middle of the waveform file 114-4, the waveform file 114-4 is divided into the first half portion 114-4F and the second half portion 114 with this position as the division position 103. Divided into -4R. The portions before and after the division position 103 become partial data 152 and 154, respectively. That is, the partial data 152 includes the song file 106, the waveform files 114-1 to 114-3, and the first half portion 114-4F of the waveform file 114-4. The partial data 154 includes a latter half portion 114-4R of the waveform file 114-4, a library file 126, and waveform files 124-1, 124-2.

  Next, a tar-format backup file 140 shown in FIG. 4B is created for each partial data. In FIG. 4 (b), 142,..., 142 are tar headers, and the file name (full path including folder and file name) following the tar header, the size of the file, the creation time of the file, The file type of the file is stored. Reference numeral 146 denotes a name list portion, which records a name list in which the song names of all song data included in the data string 150 and the library names of all library data are listed in the order of appearance in the data string 150.

That is, for the partial data 152, the song file 106, the waveform files 114-1 to 114-3, and the file “5” of the first half portion 114-4F of the waveform file 114-4 are stored in the data portions 148-1 to 148-N. As for the partial data 154, the latter half portion 114-4R of the waveform file 114-4, the library file 126, and the files “4” of the waveform files 124-1, 124-2 become the data portions 148-1 to 148-N. . In the tar header 142 corresponding to the first half portion 114-4F and the second half portion 114-4R of the waveform file 114-4, a file name having the same name as the original file name of the waveform file 114-4 is recorded.

The user can move the cursor 60 up and down by operating the operator group 6 and can switch the selection state of the song data or the like at the cursor position. 54 designates a song designation button and 56 designates a library designation button, and only one of them is selectively set to an ON state based on a user operation. When the song designation button 54 is turned on, a list of song names is displayed in the data list section 52, and when the library designation button 56 is turned on, a list of library names is displayed in the data list section 52. Reference numeral 57 denotes an execution button. When this button is pressed, restoration of the song data and library data selected in the data list section 52 is started. Reference numeral 58 denotes a cancel button. When pressed during restoration, the restoration process is interrupted.

3.2. Next, when the execution button 47 is pressed on the backup screen 40 described above, the backup execution routine shown in FIG. 7 is started. When the process proceeds to step SP2 in FIG. 7, a name list listing the song names of the selected song data and the library names of the library data is created in the data list section 42, and the song data and library data are arranged in the order of the name list. A data string 150 (see FIG. 4A) is determined. Next, when the process proceeds to step SP4, a backup ID is determined based on the current date and time. Next, when the process proceeds to step SP6, a message prompting to set the first new disk in the CD-RW drive 32 is displayed on the display 2. Next, when the process proceeds to step SP8, it is determined whether or not a new disk (CD-R or CD-RW) is set in the CD-RW drive 32. If “NO” is determined here, the process proceeds to step SP10 to determine whether or not the cancel button 48 is pressed. If "NO" is determined here, the process returns to the step SP8. Thereafter, the loop of steps SP8 and SP10 is repeated. If the cancel button 48 is pressed during that time, the process proceeds to step SP24, and the backup process is canceled.

  When a new disk is set in the CD-RW drive 32, the process proceeds to step SP12, and the capacity of the new disk is detected. For example, currently available disks such as CD-R and CD-RW have variations in capacity of “640 Mbytes” and “700 Mbytes”. Therefore, the data string 150 is divided based on the disk capacity. A division position 103 (see FIG. 4A) is determined. When the division position 103 is determined, the number of data N (N = 5 in the partial data 152 in FIG. 4A), which is the number of the data parts 148-1 to 148-N, is determined accordingly. Next, when the process proceeds to step SP14, various data of ISO9660 (CD-ROM standard) is written to the new disk. Next, when the process proceeds to step SP16, a root directory is created for the new disk.

  Next, when the processing proceeds to step SP18, the tar file write processing routine shown in FIG. 8 is called and the backup file 140 is written to the set disk (details will be described later). Next, when the process proceeds to step SP20, it is determined whether or not data to be backed up remains in the data string 150. If “YES” is determined here, the process proceeds to step SP22, and a message prompting the user to set the next new disk in the CD-RW drive 32 is displayed on the display unit 2, and the steps after step SP8 are performed. The process is repeated. On the other hand, if all the data included in the data string 150 has been backed up, “NO” is determined in step SP20, and the processing of this routine ends.

  Next, details of the tar file write processing routine (FIG. 8) called in step SP18 will be described. When the processing proceeds to step SP30 in FIG. 8, the management information section 144 is written to the set disc together with the corresponding tar header 142. Next, when the process proceeds to step SP32, the name list portion 146 is written to the disc together with the corresponding tar header 142. Next, when the process proceeds to step SP34, the count variable M for counting the data parts 148-1 to 148-N is set to “1”. Next, when the process proceeds to step SP36, it is determined whether or not the data portion 148-1 to be written first is divided data. If “YES” is determined here, the process proceeds to step SP40, and the file corresponding to the data portion 148-1 (in the example of the partial data 154 in FIG. 4A, the waveform file 114-4). ) Is read from the hard disk 30 and the contents after the division position 103 are written to the disk together with the corresponding tar header 142. On the other hand, if the data part 148-1 to be written first is not divided data, “NO” is determined in step SP36, and the process proceeds to step SP38.

  In step SP38, the file corresponding to the data part 148-M is read from the hard disk 30, and the whole is written to the disk together with the corresponding tar header 142. Next, when the process proceeds to step SP42, the count variable M is incremented by “1”. Next, when the process proceeds to step SP44, it is determined whether or not the count variable M is equal to the data number N. If "NO" is determined here, the process returns to the step SP38. Therefore, the loop of steps SP38, SP42 and SP44 is repeated until the count variable M becomes equal to the number of data N. When the count variable M becomes equal to the data number N, the process proceeds to step SP46. Here, it is determined whether or not the data portion 148-N to be written last is divided data. If “YES” is determined here, the process proceeds to step SP50, and the file corresponding to the data portion 148-1 (in the example of the partial data 152 in FIG. 4A, the waveform file 114-4). ) Is read from the hard disk 30 and the contents from the head to the division position 103 are written to the disk together with the corresponding tar header 142. On the other hand, if the data part 148-N to be written last is not divided data, “NO” is determined in step SP46, and the process proceeds to step SP48. Here, as in step SP38, the file corresponding to the last data portion 148-N is read from the hard disk 30, and the entire file is written to the disk together with the corresponding tar header 142. Next, when the process proceeds to step SP52, the binary zero byte string related to the termination unit 149 is written to the disk, and the process of this routine ends.

3.3. Restore Process Next, when the execute button 57 is pressed on the restore screen 50 described above, the restore execution routine shown in FIG. 9 is started. In FIG. 9, when the process proceeds to step SP60, the first song data or library data among the song data and library data selected in the data list section 52 is designated as a restore target. Next, when the process proceeds to step SP62, the count variable P for counting the number of the disk is set to “1”. Next, when the process proceeds to step SP64, a song file related to the restore target song data or a library file related to the library data (hereinafter referred to as the library data (hereinafter referred to as the library data)) based on the management information section 144 in the disc set in the CD-RW drive 32. These are referred to as main files). If "NO" is determined here, the process proceeds to a step SP66 to call a next disk request processing routine (FIG. 10) described later. Here, when the next disk is set by the user, the process returns to step SP64, and the processes of steps SP64 and SP66 are repeated until the disk in which the main file exists is set.

  Here, if the disc on which the main file is recorded is set, “YES” is determined in step SP64, and the process proceeds to step SP68. Here, a data read processing routine (FIG. 11), which will be described later, is called, the contents of the data portion relating to the main file are read, and the main file is restored in the hard disk 30. Next, when the process proceeds to step SP70, it is determined whether or not the data portion of the waveform file following this exists for the data portion read immediately before. If "YES" is determined here, the process proceeds to step SP72, and the data portion related to the waveform file determined to exist is read. The read data portion is restored as a waveform file in the hard disk 30, and the process returns to step SP70.

  Thereafter, as long as the data portion related to the waveform file is continuously recorded on the set disc with the tar header interposed therebetween, the loop of steps SP70 and SP72 is repeated, and each time the waveform file is repeated, the waveform file is stored in the hard disk 30. Restored. Furthermore, although details will be described later, the processing of step SP72 is repeatedly executed even when waveform files are stored across a plurality of disks. As a result, all the waveform files constituting the song data or library data are restored together with the main file restored in step SP68. As described above, when all the data portions related to the waveform file related to the main file are read out, the next data portion becomes the main file of another song data or library data. Therefore, “NO” is determined in step SP70, and the process proceeds to step SP74. Here, it is determined whether or not there is any unrestored song data and library data previously specified as the restore target. When it exists, it determines with "YES" and a process returns to step SP64. Thereafter, the processing of steps SP64 to SP74 is repeated to restore the main file and waveform file related to other song data or library data. Thus, when the restoration of all the data designated as the restoration target is completed, “NO” is determined in step SP74, and the processing of this routine is ended.

  Next, the processing of the next disk request processing routine called in step SP66 will be described with reference to FIG. When the processing proceeds to step SP100 in FIG. 10, it is determined whether or not the disc currently inserted in the CD-RW drive 32 is the last disc. Since the next disk should not exist for the last disk, if "YES" is determined here, the process proceeds to step SP102, and after a predetermined error process is executed, the restore process itself is performed. Is terminated. On the other hand, if “NO” is determined in step SP100, the process proceeds to step SP104, and the count variable P is incremented by “1”. Next, when the process proceeds to step SP106, a message is displayed on the display 2 so that the Pth disc is set in the CD-RW drive 32.

  Next, when the process proceeds to step SP108, it is determined whether or not the Pth disc has been set in the CD-RW drive 32. That is, the contents of the management information unit 144 included in the set disk are read, and it is determined whether or not the Pth disk having the same backup ID as the disk set previously is actually set. Is done. If “YES” is determined here, the process returns to the restore execution routine (FIG. 9). On the other hand, if “NO” is determined here, the process proceeds to step SP110. Note that if the backup ID of the set disk is different from the previous one, or if a disk other than the Pth disk is set even if the backup IDs match, the error message “Disk is different” Is displayed on the display 2. Next, in step SP110, it is determined whether or not the cancel button 58 has been pressed. If "YES" is determined here, the process proceeds to step SP112, and a predetermined cancel process is executed. In other words, the main file and the waveform file constituting one song data or library data should be handled as one body, and if only a part of them is restored, the consistency in the song data or library data cannot be obtained. For this reason, when only a part of the song data or library data up to step SP112 is restored, all the restored files in the hard disk 30 are deleted, and the state before restoration is restored.

  Next, the processing of the data read processing routine called in the above steps SP68 and SP72 will be described with reference to FIG. In FIG. 11, when the process proceeds to step SP120, the contents of the data part which is the current reading target among the data parts 148-1 to 148-N stored in the currently set disk are read into the hard disk 30. It is. Such processing is slightly different between the case of reading the data portion related to the main file and the case of reading the data portion related to the waveform file. First, before reading the main file, it is unknown which position (how many bytes) the main file is in the backup file 140. Therefore, the contents of the disc are searched until the tar header 142 immediately before the main file is found, and the contents of the main file are read into the hard disk 30 after the tar header 142 is found.

  On the other hand, as shown in the format of FIG. 4A, each waveform file is always recorded following the main file or another waveform file (which constitutes the same song data or library data). Therefore, when the main file or another waveform file is read into the hard disk 30, the next waveform file is recorded following the tar header 142 while maintaining the current tracking state of the pickup unit of the CD-RW drive 32. Can be read. Thus, in this embodiment, each waveform file is recorded continuously after the main file, so that the waveform file can be read out at a very high speed.

  Next, when the process proceeds to step SP122, it is determined whether or not the read data portion is a divided data portion. If “YES” is determined here, the process proceeds to step SP124, and the above-described next disk request processing routine (FIG. 10) is called. When the next disk is set, the process proceeds to step SP126, and the head data portion 148-1 of the set disk is append-read from the disk to the hard disk 30, and the process of this routine ends. That is, the data read from both steps SP120 and SP126 are combined, and one file is restored to the hard disk 30.

  On the other hand, if “NO” is determined in step SP122, the process proceeds to step SP122, and it is determined whether or not the previously read data portion is the last data portion in the current disk. If “NO” is determined here, the processing of this routine is immediately terminated. On the other hand, if the read data portion is the last data portion in the disk, the process proceeds to step SP30, and it is determined whether or not the currently set disk is the last disk. If “YES” is determined here, the processing of this routine is immediately terminated. On the other hand, if the set disk is a disk other than the last disk, the process proceeds to step SP132, and the above-described next disk request processing routine (FIG. 10) is called.

Four. Modifications The present invention is not limited to the above-described embodiments, and various modifications can be made as follows, for example.
(1) In the above embodiment, the waveform file 114-4 in FIG. 4A is divided into the first half portion 114-4F and the second half portion 114-4R and recorded across the two backup files. Since the process for restoring this file is simply to combine the data parts of the same name in the same folder stored in the two previous and subsequent tar files, the same process as in the above-described embodiment can be performed in the program on the personal computer. It may be executed and may be used for other purposes (for example, DTM on a personal computer). However, even in this case, it is desirable to check whether the backup IDs recorded in the management information portions 144 of the preceding and succeeding disks are consistent.

(2) In the above embodiment, the division position 103 (step SP12) is checked each time a disk is set while checking the capacity (640 Mbyte, 700 Mbyte, etc.) of the set CD-R, CD-RW, etc. ) Was decided. However, first, the disk capacity may be fixed to one type based on an instruction from the user, and thereafter, the user may be requested to set a new disk of that capacity. According to such a configuration, the number of disks required for backup can be displayed on the display unit 2 before the backup starts. Further, since it is also known in advance to which disc each song data or library data is recorded, the information can be included in the name list portion 146 and recorded on each disc. In that case, when executing the restore, it is not necessary to ask the user to set in order from the first disk, and the user is instructed to set only the disk containing the specified song data or library data. be able to. As a result, it is possible to reduce the time and effort required for restoration as well as the time and effort of the user. Further, in such a case, the “recording range” information can be omitted in the management information unit 144 in the backup file 140.

(3) In the above embodiment, the CD-RW drive 32 is set in order from the first disk at the time of restoration. However, the disks may be set and restored in an arbitrary order. .

(4) In the above embodiment, the backup and restore processing is performed by the program operating on the CPU 8, but only this program is stored and distributed in a recording medium such as a CD-ROM or a memory card, or through a transmission line. It can also be distributed.
