BACKGROUND OF THE INVENTION
The present invention relates to a music apparatus provided with writing means for writing music data on a recording medium by a disc-at-once method that can be written only once but cannot be additionally written.
[0002]
[Prior art]
Conventionally, when a personal music album is created by a PC (personal computer) and written on a CD, first, music data to be written from the music CD to the CD is taken into the PC. Next, the user performed a rearrangement operation in the order in which he / she wanted to listen to the music, performed a setting operation so that the music player could listen to the music, and finally wrote the music data on the CD-R. Writing to the CD-R is performed by a so-called disk-at-once method in which writing is possible only once and additional writing is not possible. In addition, as a conventional technique, the playback data reproduced from the video deck is divided into predetermined sections, a button for selecting the divided predetermined sections is provided on the screen, and editing is performed so that only the predetermined predetermined sections are extracted and edited. A reproduction data device for writing later data to a DVD has been proposed (for example, see Patent Document 1).

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. Hereinafter, as an example of a music apparatus, a multi-track recorder 1 that manages music data as a file and can simultaneously reproduce a plurality of tracks of music data will be described as an example.
[0010]
(Constitution)
FIG. 1 is a configuration diagram of a multitrack recorder 1 according to an embodiment of the present invention. As shown in FIG. 1, the multitrack recorder 100 includes a CPU 110, a ROM 111, a RAM 112, a USB controller 120, an HD 130, an operation unit 140, a liquid crystal display 150, a musical tone signal input unit 160 connected to an input terminal 161, and an output terminal 171. A musical tone signal output unit 170 to be connected, a CD-R writer 180, and a PC I / F (interface) 190 connected to a data input / output terminal 191 are provided. The CPU 110 is configured to implement the following operations by executing control software recorded in the ROM 111, an overall control program recorded in the HD 120, and the like.
[0011]
Further, the CPU 110 is configured to receive an instruction by an operation of the operation unit 140, perform a required operation, and display necessary information on the liquid crystal display 150. The liquid crystal display 150 is formed with an information display unit and a touch panel unit (corresponding to the display button group 152 in FIG. 2) as an information input unit, so that necessary information can be input by a touch operation on the touch panel unit. It is configured. Although not shown in detail, the operation unit 140 is composed of a large number of slider switches such as mixing and equalizing adjustment, various operation parts such as push-down buttons and dials for performing instruction selection operations. Furthermore, the PC I / F 190 communicates necessary information (mainly data files and the like) with a personal computer outside the apparatus via the data input / output terminal 191 under the control of the CPU 110.
[0012]
In response to the musical sound signal recording instruction operation of the operation unit 140, the CPU 110 causes the musical sound signal input unit 160 to input a musical sound signal input via the input terminal 161. The musical tone signal input unit 160 converts the inputted musical tone signal from analog to digital, and this is transferred to the CPU 110 as digital musical tone data. The CPU 110 temporarily stores this in the RAM 112, then stores it in a file in the management area of the HD 130, and further stores it in a user area that can be accessed (read and written). On the other hand, when the CPU 110 passes the music data of a plurality of files stored in the user area to the music signal output unit 170 in response to the music signal reproduction instruction operation of the operation unit 140, the music signal output unit 170 receives the plurality of music data. Are simultaneously converted to digital to analog and output to the output terminal 171. Thus, the multi-track recorder 100 can manage each of the sound data of a plurality of tracks as a file and obtain a sound signal obtained by simultaneously reproducing the plurality of tracks.
[0013]
In addition, the CD-R writer 180 is configured to write music data to the inserted CD-R by a disc-at-once method that can be written only once and cannot be additionally written. This writing instruction is performed, for example, by operating the touch panel unit described above.
[0014]
FIG. 3 is an explanatory diagram of the management table 300 stored in a predetermined area of the HD 130. The management table 300 stores and manages a file name (file identifier), an address range in which the file is stored, and an actual performance time of the file in association with each other. When a new file is generated, the CPU 110 registers the file name input from the operation unit 140 and stores the actual performance time of this file and the storage address range in association with each other in the management table 300. The example of FIG. 3 shows that the actual performance time of the file with the file name “FA” is “3 minutes 30 seconds” and is stored in the address range “AD1 to AD2”. Thus, each file generated by the multitrack recorder 1 is managed by the CPU 110 using the management table 300.
[0015]
FIG. 5A is an explanatory diagram of a play table 500 stored in the HD 130. The play table 500 stores tracks (song order), file names, pre-gap, post-gap, and actual performance time in association with each other. Here, the pre-gap is a silence (blank data) part provided before the music data, and the post gap is a silence (blank data) part provided after the music data. Both gaps can be set by operating the touch panel unit as will be described later, and the set values are stored in the “pre-gap” and “post-gap” fields of the play table 500, respectively. In addition, the track which is the music data reproduction order can also be set by operating the touch panel unit, and the selected file names are stored in track 1, track 2, track 3,.
[0016]
Then, the CPU 110 retrieves the actual performance time corresponding to the stored file name from the management table 300 and stores the retrieved actual performance time in the “actual performance time” column of the play table 500. Thus, the play table 500 is constructed by selecting and setting the track, pre-gap, and post-gap.
[0017]
FIG. 5B is an explanatory diagram of the pre-reproduction table 510 stored in the HD 130. The pre-reproduction table 510 stores a reproduction start time, a reproduction time, and a file address in association with each other. Now, when the play table 500 is constructed as shown in FIG. 5A, how the pre-reproduction table 510 is constructed will be described. First, the playback start time of the file “FA” whose playback order is “1” is set to the initial playback start time “0:00”. Since this playback time is “3 minutes 30 seconds” as shown in the play table 500, it is stored in the pre-play table 510. Then, the address range “AD1 to AD2” for the file name FA is retrieved from the management table 300 and stored in the corresponding position in the pre-reproduction table 510. Thus, information of each column in the first row of the pre-reproduction table 510 is constructed.
[0018]
Next, the reproduction start time of the file “FB” whose reproduction order is “2” is obtained. At this time, the CPU 110 post-gap for the reproduction order “1” (in this example “0 minutes 04 seconds”). And a pre-gap for the reproduction order “2” (in this example, “0 minute 00 second”) is obtained from the play table 500, and the first music data of the reproduction order with respect to the initial reproduction start time is obtained. The time “3 minutes 34 seconds” obtained by adding the reproduction time, the obtained post gap, and the pre gap is stored in the pre-reproduction table 510 as the second reproduction start time in the reproduction order. Since this playback time is “20:00” as indicated by the play table 500, it is stored in the pre-play table 510. Then, the address range “AD3 to AD4” for the file name FB is retrieved from the management table 300 and stored in the corresponding position in the pre-reproduction table 510. Thus, information of each column in the second row of the pre-reproduction table 510 is constructed.
[0019]
Next, the reproduction start time of the file “FC” whose reproduction order is “3” is obtained. At this time, the CPU 110 post-gap for the reproduction order “2” (in this example, “0 minute 01 second”). And the pre-gap for the reproduction order “3” (in this example, “0 minutes 02 seconds”) is retrieved from the play table 500, and reproduction is performed with respect to the reproduction start time of the music data whose reproduction order is second. The time “5 minutes 37 seconds” obtained by adding the reproduction time of the second music data in the order and the obtained post gap and pre-gap is stored in the pre-reproduction table 510 as the third reproduction start time in the reproduction order. Since this reproduction time is “40:00” as indicated by the play table 500, it is stored in the pre-reproduction table 510. Then, the address range “AD5 to AD6” for the file name FC is retrieved from the management table 300 and stored in the corresponding position in the pre-reproduction table 510. Thus, information of each column in the third row of the pre-reproduction table 510 is constructed.
[0020]
In this way, the above operation is repeated until the pre-reproduction table is constructed for the music data having the last reproduction order. Then, at the time of pre-reproduction, the CPU 110 reproduces music data according to the elapse of the reproduction start time shown in the pre-reproduction table 510. In the example of FIG. 5B, the file FA in the address range “AD1-AD2” is reproduced at the time “0:00”, and then the file in the address range “AD3-AD4” at the time “3:34”. The FB is reproduced, and the file FC in the address range “AD5 to AD6” is reproduced at the time “5 minutes 37 seconds”. Therefore, as shown in FIG. 6, the file addresses need not be mapped in the reproduction order. In other words, when storing a file, it is not necessary to consider the address mapping order.
[0021]
FIG. 2 is an explanatory diagram of a display example of the display screen 151 of the liquid crystal display 150. A display button group 152 having various touch panel type buttons is formed at the bottom of the screen, and an input screen 153 for inputting information on music data to be written to the CD-R by the disk-at-once method above it. Is formed. Each time the music order button 204 is pressed, numbers are displayed in the track (music order) display area so as to increase in numbers such as “1”, “2”, “3”,. When one of the selectable file names is selected for the displayed music order, the CPU 110 displays the selected file name in the file name column, and the actual performance time for this is displayed from the management table 300. Find it and display it in the display column of the corresponding actual performance time. In the example shown in FIG. 2, the file names FA, FB, and FC are selected for track 1, track 2, and track 3, in other words, the playback order is input as files FA, FB, and FC. . Correspondingly, the actual performance times such as “3 minutes 30 seconds”, “2 minutes 00 seconds”, and “4 minutes 00 seconds” are displayed in the actual performance time display column.
[0022]
Further, it is possible to set a pre-gap on the input screen 153 by operating the pre-gap button 208 with respect to the music data in each reproduction order, and operate the post-gap button 210 on the input screen 153. The post gap can be set with. In the example of FIG. 2, the pregap of the reproduction order “1” is set to “Pre1”, and the post gap is set to “Po1”.
[0023]
Information on the track (song order), file name, pregap, and postgap input on the input screen 153 is stored in the play table 500. The CPU 110 retrieves the actual performance time for the file with the file name from the management table 300 and stores it in the corresponding position of the play table 500, whereby the play table 500 is constructed. Then, as described above, the pre-reproduction table 510 is constructed based on the stored contents of the play table 500 and the address range of the management table 300. Thus, the CPU 110 displays the input screen 153 on which information regarding a plurality of music data to be written to the CD-R can be input, and accepts information input on the input screen 153 by operating various operation buttons. The information for pre-reproducing a plurality of music data is registered before the writing operation to the CD-R.
[0024]
(Overview of operation)
Next, an outline of the operation performed by the CPU 110 will be described with reference to the flowchart of FIG. First, in step S400, an input screen 153 that is a playlist for creating a CD album is displayed. In step S405 and step S410, when the order of music and the pre-gap / post gap are input, they are received and registered in the play table 500. In step S415, if there is still a song to be written (Yes), the processes in steps S405 and S410 are repeated. On the other hand, if there is no song to be written (No), the playback button 200 shown in FIG. The pre-reproduction described above is performed. That is, after the play table 500 is constructed as described above, the pre-reproduction table 510 is constructed, and the music data is reproduced before writing to the CD-R according to the construction contents of the pre-reproduction table 510. Do.
[0025]
If the song order and the gap (gap) are correct in step S425 (Yes), the process proceeds to step S445. If the song order and gap (gap) are not correct (No), the play table 500 is edited to change the song order and the gap between songs. (Step S430). If the level of each song is correct in step S445 (Yes), the process proceeds to step S450. If not correct (No), the level is adjusted by operating the level adjustment button 202 (see FIG. 2) in step S435. Is adjusted (step S435). Further, if the tone color is correct (Yes) in step S450, the process proceeds to step S455. If the tone color is not correct (No), in step S440, the effect button 203 (see FIG. 2) is operated to apply the effect and the tone color is applied. Is adjusted (step S440).
[0026]
In step S455, the write button 201 shown in FIG. 3 is pressed to cause the CD-R writer 180 to perform the operation of writing music data to the CD-R with the set music order and gap.
[0027]
Therefore, according to this embodiment, the CPU 110 displays the input screen 153 on which information related to a plurality of music data to be written to the CD-R can be input, and input on the input screen 153 by operating various operation buttons. The received information is received, and information for pre-reproducing a plurality of music data is registered before the writing operation to the CD-R. Then, by referring to this registration information, a plurality of music data to be written can be reproduced before the writing operation is performed, so that it is possible to pre-listen to music data before writing with disc-at-once. become able to.
[0028]
In the information registration described above, the reproduction start time of the music data in the reproduction order “No. 1” is registered as a preset initial reproduction start time (for example, “0:00”), and the music data in the reproduction order No. 1 is registered. For the playback order “2”, the actual performance time set in advance, the post-gap time of the input playback order “No. 1”, and the pre-gap time of “No. 2” are added to the initial playback start time. Is registered as the reproduction start time (second reproduction start time) of the music data of “No.”, the actual performance time preset for the music data of this reproduction order “No. 2”, and the input reproduction order “2” “Time” post gap time and “No. 3” pre-gap time added to the second playback start time are registered as the playback start time (third playback start time) of the music data in the playback order “No. 3”. The last playback Ban (n number: n is an integer of 4 or more) is performed until the registration of the playback start time for the music data, also registering the reproduced address ranges for each reproduction order of the music data. The CPU 110 plays the music data in the corresponding playback address range according to the arrival of each playback start time before the write operation is performed, so that the playback start can be performed without worrying about the storage address of the music data. Music data can be played according to the schedule according to the time.
[0029]
(Other embodiments)
In this other embodiment, stream data 800 as a series of music data as shown in FIG. 8 is divided at, for example, two mark positions M1 and M2, and automatically CD-as three files MA1, MA2 and MA3. It is characterized in that it is a file to be written to R.
[0030]
First, it is assumed that the stream data 800 is being reproduced. First, in step S700 in FIG. 7, the CPU 110 determines whether or not the marker button 211 in FIG. 3 has been pressed. If it is determined that the marker button 211 has not been operated (No), the CPU 110 enters a wait state in step S700. On the other hand, if it is determined that the marker button 211 has been pressed (Yes), in step S710, information necessary for the mark list is registered in order to set the position indicated by the marker button 211 as the marker position, and the process proceeds to step S700. Return. For example, when the first marker position is indicated by M1 in FIG. 8, the file name MA1, the actual performance time PA, and the address range “AD7 to AD8” for storing this are registered in association with each other as shown in FIG.
[0031]
Similarly, when the next marker position is indicated by M2 in FIG. 8, the file name MA2, the actual performance time PB, and the address range “AD9 to AD10” for storing them are registered in association with each other as shown in FIG. . When M2 is the last marker position, the remaining music data is the file name MA3, and the file name MA3, the actual performance time PC, and the address range “AD11 to AD12” for storing this are shown in FIG. Register in association. The CPU 110 is configured to be able to grasp the actual performance time from the start of playback to the marker position, between the marker positions, and from the last marker position to the end of playback.
[0032]
Then, the CPU 110 copies the contents of the constructed mark list 900 to the management table 300, so that the file generated by the mark operation can be set as a write target to the CD-R. Note that when setting the marker position, a message such as “Where is the marker position good?” Is displayed, and the mark list registration may be performed only when an OK operation is performed on this message.
[0033]
Although the embodiments of the present invention have been described above, various modifications and changes can be made to the above-described embodiments without departing from the gist of the present invention. For example, in the above description, only the three music data files FA, FB, and FC are to be written, but four or more types are generally to be written (n is an integer of 2 or more). Needless to say, you can. Further, the addresses of the files do not necessarily have to be continuous.
[0034]
