The use of is spreading. NFC is a card-type tag that conforms to a standard called FeliCa (registered trademark) in Japan (an NFC tag is referred to as an “NFC tag” and an NFC reader is referred to as an “NFC reader”). For example, prepaid cards for stores and prepaid cards are widely used. Currently, NFC IP-1 (Near Field Communication Interface Protocol-1), an upward compatible standard of FeliCa, has become an international standard as ISO / IEC 18092, and NFC IP-2 (Near Field) is an extension of NFC IP-1. Communication Interface Protocol-2) is an international standard as ISO / IEC 21481. In response to the international standardization of NFC, some slate devices such as smartphones and tablet PCs that incorporate an NFC reader that reads data from an NFC tag have appeared. An NFC reader having a function of writing data to an NFC tag is called an NFC reader / writer.

  In NFC, an NFC reader constantly transmits an electromagnetic wave having a predetermined frequency. When the NFC tag comes close to the NFC reader within a distance of about several centimeters to several tens of centimeters, the NFC tag receives electromagnetic waves transmitted from the NFC reader with a strength higher than a predetermined strength. The NFC tag obtains an electromotive force due to electromagnetic induction in an RF magnetic field generated by an electromagnetic wave received from an NFC reader, and transmits response data using the electromotive force or an electromagnetic wave having a predetermined frequency using the generation of the electromotive force as a trigger. Thereafter, transmission / reception of data using electromagnetic waves is performed between the NFC reader that has received the response data and the NFC tag.

  As described above, the NFC tag transmits / receives data to / from the NFC reader only when the NFC tag is close to the NFC reader within a distance of several centimeters to several tens of centimeters. The data stored in the NFC tag can be read by the NFC reader by an easy-to-understand action of holding the NFC reader (close to within a distance of several centimeters) or bringing it into contact (touching).

  When the NFC tag of the tablet PC 21 is held over the NFC reader / writer of the audio smart box 11, the data stored in the own device is transmitted to the NFC reader / writer of the audio smart box 11. As a result, the NFC reader / writer of the audio smart box 11 acquires the data stored in the NFC tag of the tablet PC 21. Hereinafter, a process in which the NFC reader / writer acquires data stored in the NFC tag held over the self-machine is described as “the NFC reader / writer reads data from the NFC tag”.

  The audio smart box 11 uses the short-range wireless communication unit 1117 to perform the non-short-range wireless communication of the audio smart box 11 according to the data indicating the standard name and encryption method of the non-short-range wireless communication read from the NFC tag of the tablet PC 21. The SSID set in the communication unit 1118, the data indicating the encryption method, and the encryption key are transmitted to the NFC tag of the tablet PC 21. The NFC tag of the tablet PC 21 stores the SSID and the like transmitted from the audio smart box 11 in its own storage area. Hereinafter, the process of storing data transmitted from the NFC reader / writer held by the NFC tag in the storage area of the NFC tag is referred to as “NFC reader / writer writes data to the NFC tag” for convenience. It describes as follows.

  When the audio smart box 11 completes writing of the SSID and the like to the NFC tag of the tablet PC 21, for example, an electronic sound generator (not shown) emits an electronic sound “beep” to notify. The user V may freely release the tablet PC 21 from the audio smart box 11 after this notification.

  The audio smart box 11 uses the wired communication IF 1116 (the transmission unit 116 and the reception unit 117) for the cloud storage on the Internet 9 identified by the URL read from the tablet PC 21, and the user name and password read from the tablet PC 21. A transmission request command for a list of DAW data is transmitted. The audio smart box 11 receives a list of DAW data transmitted from the cloud storage in response to the transmission request command via the wired communication IF 1116.

  On the other hand, the tablet PC 21 uses the data such as the SSID written in the audio smart box 11 to transmit a non-short-range wireless communication connection establishment request command to the audio smart box 11 by its own non-short-range wireless communication unit. I do. The non near field wireless communication unit 1118 of the audio smart box 11 responds to the establishment request command from the tablet PC 21 and follows a predetermined protocol according to the standard of the non near field wireless communication, and the non near field wireless communication unit of the audio smart box 11 A non near field wireless communication connection is established between 1118 and the non near field wireless communication unit of the tablet PC 21. Thereafter, since the audio smart box 11 and the tablet PC 21 can perform data communication via the non-short-range wireless communication connection, the user V does not need to repeat the operation of holding the tablet PC 21 over the audio smart box 11. .

  Subsequently, the audio smart box 11 transmits a list of DAW data received from the cloud storage to the tablet PC 21. Using the list of DAW data received from the audio smart box 11, the tablet PC 21 displays a DAW data operation screen as shown in FIG.

(1) Identification data of own device (2) Data such as “electric base” indicating the type of the electric base 17 (3) “standard phone plug” indicating the shape of the terminal of the cable used to connect the electric base 17 Data (4) Data such as “** dBv” indicating the output level of the electric base 17 (5) Effector parameters according to the electric base 17 (6) URL of the cloud storage
(7) User name and password

  The data (1) to (4) stored in the NFC tag 18 is normally fixed data that is not rewritten, and is attribute data indicating the attribute of the electric base 17. The data (5) is the data written by the NFC reader / writer of the audio smart box 11 (if the practice studio is different, a different device of the same type as the current device) during the previous practice, for example. This is instruction data for instructing the audio smart box 11 of the processing contents of the sound waveform data input from the electric base 17 to the audio smart box 11. The data (6) and (7) are data written by the user B using, for example, an NFC reader / writer connected to a PC or the like.

  User B holds the NFC tag 18 over the audio smart box 11. When the NFC reader / writer of the audio smart box 11 reads data from the NFC tag 18, the analog sound signal input IF 1109 (sound waveform data input unit 111) includes a plurality of units according to the attribute data of the electric base 17 included in the read data. Among these input terminals, a standard input terminal suitable for connection to the electric base 17 (that is not connected to other devices) is selected, and a guide image as shown in FIG. 10 is displayed on the display 1107, for example. User B connects electric base 17 to the input terminal designated by the shielded cable in accordance with the guidance image displayed on display 1107. Thereby, the audio smart box 11 can specify to which input terminal the electric bass 17 is connected.

  Further, the audio smart box 11 reads out the plug-in program of the designated effector according to the instruction data (effector parameters) received from the NFC tag 18 and plugs it into the DAW application, and sends the designated parameters to those effectors. Set. The processing when the designated effector is not installed in the audio smart box 11 is the same as when the NFC tag of the receiver 16 is held over the audio smart box 11.

  In this way, the user B holds the NFC tag 18 over the audio smart box 11 and connects the electric base 17 to the audio smart box 11 according to the instructions of the audio smart box 11, thereby connecting the electric base 17 to the audio smart box 11.

  The user K brings a music keyboard 19 and a USB cable. The user K connects the music keyboard 19 to an unused one of the USB terminals included in the digital signal input / output IF 1113 (sound waveform data input unit 111) of the audio smart box 11 with a USB cable. The audio smart box 11 detects the connection of the music keyboard 19 and, if necessary, downloads and installs a driver for performing data communication with the music keyboard 19 according to the USB standard via the Internet 9. Thereafter, the audio smart box 11 transmits / receives various data to / from the music keyboard 19 via the USB cable.

  In this way, the user K simply connects the music keyboard 19 to an available terminal of the audio smart box 11 with the USB cable without holding the NFC tag over the audio smart box 11. This is because the music keyboard 19 can perform various types of data communication with the audio smart box 11 via the USB cable, and the audio smart box 11 can be connected from the music keyboard 19 to the device type of the music keyboard 19 via the USB cable. This is because it is possible to receive attribute data such as data indicating the terminal to which the music keyboard 19 is connected.

  Moreover, the music keyboard 19 has a built-in effector, and it is not always necessary to use the plug-in effector in the audio smart box 11. Therefore, the effector parameters used by the music keyboard 19 may not be transmitted as instruction data to the audio smart box 11. Various parameters (tone color setting parameters, effector parameters, etc.) in the music keyboard 19 can be recorded in the DAW data, for example, in the format of MIDI exclusive data. In that case, when the audio smart box 11 plays back the performance according to the DAW data, various parameters are transmitted from the audio smart box 11 to the music keyboard 19, and these parameters are set in the music keyboard 19. Done.

  A user V brings a wireless microphone 20 and a tablet PC 21. The user V operates the tablet PC 21 to display the mode selection screen (FIG. 6) of the ASB application, and operates the “device connection” button by touching or the like. In response to the operation, the tablet PC 21 displays a device connection screen as shown in FIG. On the device connection screen, a list of devices registered in advance in the tablet PC 21 by the user V is displayed.

  When the user V selects any device from the list by touch or the like, the attribute data such as the device type registered for the selected device and the instruction data such as the effector parameters are displayed below the list. The Among these data, the attribute data can be input by manually reading data stored in advance in the NFC tag attached to the device with the NFC reader / writer of the tablet PC 21 or by operating the tablet PC 21 by the user V. Data. The instruction data is data written by the NFC reader / writer of the audio smart box 11 (if the practice studio is different, a different device of the same type as the device used this time) during the previous practice, for example.

In this case, the user V selects “wireless microphone” from the list on the device connection screen by touching or the like. In response to this selection, the tablet PC 21 reads, for example, the following data from the storage means (SSD or the like) included in the tablet PC 21.
(1) Identification data of own device (2) Data such as “wireless microphone” indicating the type of device (3) Frequency used by wireless microphone (4) Effector parameter according to wireless microphone (5) Cloud storage URL
(6) User name and password

  Subsequently, the user V operates the “connect” button displayed on the device connection screen by touching or the like. In response to this operation, the tablet PC 21 transmits the data (1) to (6) read from the storage means of the own device to the audio smart box 11. The audio smart box 11 determines the frequency indicated by the data read into one of the unused channels of the analog wireless sound signal receiving unit 1115 (sound waveform data input means 111) according to the attribute data included in the data received from the tablet PC 21. Set. As a result, the audio smart box 11 can receive electromagnetic waves indicating sound waveform data transmitted from the wireless microphone 20.

  In addition, the audio smart box 11 reads out the plug-in program of the designated effector according to the instruction data included in the data received from the tablet PC 21, plugs it into the DAW application, and sets the designated parameters in those effectors. . The processing when the designated effector is not installed in the audio smart box 11 is the same as when the NFC tag of the receiver 16 is held over the audio smart box 11.

  Thus, the user V can complete the connection work of the wireless microphone 20 to the audio smart box 11 and the effector parameter setting work by operating the tablet PC 21.

  As described above, every time a device of each user is connected to the audio smart box 11, the audio smart box 11 assigns a channel to which the device is connected to a track in the DAW in the DAW application. When a device already assigned to a specific track by DAW data is connected to the audio smart box 11, the audio smart box 11 assigns the channel of the device to the track of the device. Further, when a device not assigned to a specific track is newly connected by DAW data, the audio smart box 11 assigns the channel of the device to an unused track.

  When the audio smart box 11 assigns a channel of a new device to an unused track, for example, a template stored in advance for each combination of device types according to the device type and input level indicated by the attribute data of the device. Based on the data, the amplification factor (mixing level) of each track is adjusted. When the audio smart box 11 assigns a channel of a new device to an unused track, for example, based on template data stored in advance for each combination of device types, the audio smart box 11 changes the device type indicated by the attribute data of the device. Adjust the pan (orientation) of each track accordingly. Furthermore, when the audio smart box 11 assigns a channel of a new device to an unused track, the audio smart box 11 corresponds to the device type indicated by the attribute data of the device based on, for example, template data stored in advance for each device type. A general effector is plugged into the track, and general parameters are set for the plugged-in effector.

  Therefore, even when a new device is connected to the audio smart box 11, the user can start practicing performance in a somewhat good state without adjusting the mixing level, adjusting the pan, and setting the effector. Can do.

  In this example, there is no drum player who is a musical instrument part constituting a general band, but it is conceivable that the drum part is supplemented by automatic performance using a normal function in the DAW application. In this case, for example, the sound waveform data of the drum part automatically generated by the sound source unit 1105 according to the MIDI data is used by mixing with the sound waveform data input to the audio smart box 11 from a device such as the electric guitar 14.

  As described above, when all users connect their devices to the audio smart box 11, the users can start playing. The sound waveform data indicating the instrumental sound and singing sound input from each device to the audio smart box 11 by each performance of the user is in accordance with the instruction data received by the audio smart box 11 from the NFC tag or the like corresponding to each device. After being subjected to effect processing and mixing processing by the DSP 1106 (sound waveform data processing means 112), it is output to the speaker 12 via the analog sound signal output IF 1110 (sound waveform data output means 113), converted into sound and released. Sounded.

  The user uses the DAW interface displayed on the display of the tablet PC 21 to perform various operations that can be performed in the DAW, such as basic operations such as playing, stopping, and recording the performance, adjusting the mixing level, and changing effector settings. The operation can be performed.

  In addition, the user operates the tablet PC 21 to display the DAW data operation screen (FIG. 8) at any timing such as during practice or when the practice is completed, and operates the “save” button by touching, etc. The DAW data updated in the audio smart box 11 can be uploaded to the storage space of the user V of the cloud storage. The DAW data uploaded in this manner is downloaded to the audio smart box 11 again and used at an arbitrary timing such as the next practice.

  In addition, each user can set the effector parameters set in the DAW at that time to the NFC tag of his / her device or the NFC tag corresponding to his / her device at any timing such as during practice or when the exercise is completed. Etc. can be written. In this case, for example, the user operates the keypad 1108 of the audio smart box 11 to place the audio smart box 11 in the “write” mode, and then touches the audio smart box 11 with the NFC tag. In the touch, the NFC reader / writer of the audio smart box 11 reads the identification data from the NFC tag, and writes the effector parameters and the like used in the device track corresponding to the read identification data to the NFC tag. Data such as effector parameters written in the NFC tag in this manner is read and used by the audio smart box 11 again at an arbitrary timing, for example, at the time of the next practice.

  As described above, according to the audio system 1, the user holds the NFC tag corresponding to the device used for playing the music over the audio smart box 11, or holds the device such as a tablet PC including the NFC tag over the audio smart box 11. Then, by operating the device, the audio smart box 11 is instructed to connect the device, the device is automatically connected, and various settings of the effector and the mixer are automatically performed. be able to. As a result, the user can easily enjoy playing the music without being bothered by the connection and setting work of the device.

  In addition, according to the audio system 1, the audio smart box 11 can receive various data (for example, a program such as a DAW application or an effector plug-in) from an external resource via a WAN such as the Internet 9, and the like. (User data such as DAW data) is automatically acquired, so the user needs to prepare and bring the necessary data in advance even when performing performances in different practice studios, for example. Absent.

[Modification]
The above-described embodiments can be variously modified within the scope of the technical idea of the present invention. Examples of these modifications are shown below.

(1) In the above-described embodiment, the case where the audio system 1 is used for playing music by a band has been described as an example. The audio system 1 is not limited to the performance of music by bands, but can be used in various other applications involving input, processing, and output of sound waveform data.

  For example, the audio system 1 can be used as a network karaoke system. In that case, the audio smart box 11 is arranged in a box of a karaoke store, for example. The audio smart box 11 executes an application for karaoke, downloads karaoke data of a song specified by the user from a cloud storage storing karaoke data of various songs, and displays karaoke performance and lyrics according to the downloaded karaoke data. Etc.

  The user operates a terminal device such as a smartphone or tablet PC equipped with an NFC reader / writer and an NFC tag, for example, downloads a list of song names of karaoke data from the cloud storage, and selects a song to sing from the list To do. The identification data of the selected music is stored in the NFC tag of the terminal device. Thereafter, when the user holds the terminal device over the audio smart box 11, the audio smart box 11 reads the identification data of the music from the NFC tag of the terminal device, downloads karaoke data corresponding to the read identification data from the cloud storage, Start playing karaoke and displaying lyrics.

  Instead of holding the terminal device over the audio smart box 11 after selecting the music piece in the terminal device, the user holds the terminal device over the audio smart box 11 before selecting the music piece, and the terminal device and the audio smart box 11 are connected. The music may be selected after the non-short-range wireless communication connection is established. In that case, the identification data of the music selected by the user is transmitted to the audio smart box 11 by non-short-range wireless communication connection.

  The route for the user to download the list of karaoke data to the terminal device is determined by the method in which the terminal device directly downloads from the cloud storage via the wide area wireless data communication network, the operation of holding the terminal device over the audio smart box 11 Any of the methods of downloading from the cloud storage via the audio smart box 11 after the non-short-range wireless communication connection is established between the apparatus and the audio smart box 11 may be used.

  In addition, after the non-short-range wireless communication connection is established between the terminal device including the NFC tag and the audio smart box 11, data transmission / reception between the terminal device and the audio smart box 11 is performed by transmitting the audio from the terminal device In many cases, it is more convenient to perform the operation through the non-short-range wireless communication connection than the short-range wireless communication by the operation over the smart box 11, but for the processing that requires confirmation of important data update, for example, It is desirable to use the non-short-range wireless communication and the short-range wireless communication properly depending on the purpose, such as requesting the user to hold the terminal device over the audio smart box 11.

  As another typical example of the use of the audio system 1, it can be considered that the audio system 1 is used as an online lesson system for musical instruments. In this case, the audio smart box 11 is placed at the home of a user who receives a musical lesson. The user purchases an NFC tag corresponding to the musical instrument he / she wants to take a lesson for and the level thereof. A similar NFC tag may be provided to the purchaser as a privilege when purchasing a musical instrument, for example. The NFC tag stores a URL of an online lesson providing site, a course ID for identifying a lesson course available to the user, data indicating a period during which the lesson can be used, and the like.

  The user connects a musical instrument such as an electronic piano to the audio smart box 11 with a USB cable or the like, and then holds the NFC tag over the audio smart box 11. The audio smart box 11 reads the data from the NFC tag, downloads data indicating the content of the lesson from the online lesson providing site according to the read data, and provides the user with the lesson of the instrument according to the data.

  As described above, according to the audio system 1, an operation for instructing music to the karaoke device, an operation for accessing an online lesson providing site, and the like are performed by using the NFC tag or the terminal device equipped with the NFC tag as the audio smart box 11. This is convenient because it is possible by the intuitive operation of holding it over.

(2) The device connected to the audio smart box 11 is not limited to the device exemplified in the above-described embodiment, and other various devices can be connected to the audio smart box 11. For example, a camera may be connected to the audio smart box 11 with a USB cable or the like, and an image showing a performance state may be displayed on the television 13 or the like, or those images may be recorded as a moving image or a still image.

(3) The format of data that the audio smart box 11 receives input and the shape of the input terminal, and the format of data output by the audio smart box 11 and the shape of the output terminal are not limited to those exemplified in the above-described embodiment. The audio smart box 11 may be configured to be able to input / output data in other formats, or the audio smart box 11 may be configured to be able to input / output data via terminals having other shapes. For example, the audio smart box 11 may be provided with a MIDI input terminal or a MIDI output terminal, and may receive MIDI data input or output MIDI data via a MIDI cable.

(4) The data generated by the audio smart box 11 may be made available to a specified large number or unspecified large number of people via, for example, SNS (Social Network Service). For example, a user who composes or performs music publishes data (DAW data, sound waveform data, etc.) indicating music generated using a DAW application, etc., so that the user can compose music or music performed by the user. Can be easily published, and people's evaluation of the music and performance can be obtained as feedback. In addition, users who are taking online music lessons can publish lesson history data so that they can maintain their willingness to take lessons by communicating with other users taking the same lessons. can do.

(5) By using a plurality of audio smart boxes 11 arranged at geographically different positions to communicate with each other via the Internet 9, communication using sounds and images between a plurality of users who are separated from each other May be possible. For example, the online lesson system for musical instruments described above assumes ASP-style automated lessons, but the teachers who provide musical instrument lessons and the students who receive musical instrument lessons are arranged at their homes. Online lessons may be made possible by exchanging sound waveform data and image data with each other via the smart box 11.

  A specific example will be described. For example, the teacher and the student each have an NFC tag storing the URL of the partner's audio smart box 11, and each holds the NFC tag over the audio smart box 11 at the lesson start time. By this operation, each audio smart box 11 tries to connect to the partner audio smart box 11 according to the URL read from the NFC tag. As a result, both the teacher and student simply hold their NFC tag over their audio smart box 11 to establish an interconnection between the teacher and student audio smart box 11. Thereafter, sound waveform data and image data are transmitted and received between the audio smart boxes 11, and an online lesson is performed.

  As described above, since an interconnection between a plurality of audio smart boxes 11 arranged at different locations is performed by an intuitive operation of holding the NFC tag over the audio smart box 11, the teacher easily provides online lessons. Students can take online lessons easily.

(6) In the audio system 1, it is possible to variously change where the data used by the audio smart box 11 is stored. For example, in the description of the embodiment described above, the DAW data is stored in the cloud storage, but may be stored in a terminal device such as a smartphone carried by the user. In addition, data such as effector parameters stored in the NFC tag may be stored in the cloud storage, and written into the NFC tag and used as necessary.

(7) In the above-described embodiment, the audio smart box 11 receives the sound waveform data input to the audio smart box 11 from the device corresponding to the NFC tag according to the instruction data read from the NFC tag held over the own device. Process. In addition to or instead of this, the audio smart box 11 is connected to a device (device connected to the audio smart box 11) according to the NFC tag according to the instruction data read from the NFC tag held over the device. On the other hand, instruction data for instructing parameter setting or the like may be output.

  As a specific example, a case is assumed where an effector configured by hardware and a digital amplifier are connected to the audio smart box 11. These effectors and digital amplifiers are examples of a device that processes sound wave data output from the audio smart box 11 or a device that generates sound wave data and inputs the sound wave data to the audio smart box 11.

  In this modification, an NFC tag storing attribute data such as data indicating the device type corresponding to each device and instruction data such as data indicating parameters is prepared in advance in the effector and digital amplifier. When the user holds these NFC tags over the audio smart box 11, the audio smart box 11 connects an effector or a digital amplifier according to the attribute data read from the NFC tag, for example, as in the case where the receiver 16 is held over the audio smart box 11. The terminal to be displayed is displayed on the display (when the effector or digital amplifier is wired to the audio smart box 11), or the effector or digital amplifier is automatically connected (the effector or digital amplifier is connected to the audio smart box 11). For wireless connection).

  Thereafter, the audio smart box 11 outputs instruction data for instructing parameter setting or the like to the effector or the digital amplifier connected to the audio smart box 11 according to the instruction data read from the NFC tag. The effector and the digital amplifier perform parameter setting for the own device according to the instruction data received from the audio smart box 11.

  According to this modification, the user can give an instruction for setting parameters to the devices by holding the NFC tag corresponding to the device connected to the audio smart box 11 over the audio smart box 11.

(8) An NFC tag corresponding to a device connected to the audio smart box 11 may be used as an operator for the user to give an instruction to the audio smart box 11. Hereinafter, a case where the user B uses the NFC tag 18 to perform an operation of adjusting the pan (localization) and volume of the track assigned to the electric base 17 in the DAW executed in the audio smart box 11 will be described as an example. To do.

  User B already holds the NFC tag 18 over the audio smart box 11 and connects the electric base 17 to the audio smart box 11 according to the guidance of the audio smart box 11. In addition, the user V already holds the tablet PC 21 over the audio smart box 11, and non-short-range wireless communication is possible between the tablet PC 21 and the audio smart box 11. In this state, for example, the user B borrows the tablet PC 21 from the user V and operates the tablet PC 21 to display the pan / volume adjustment screen of the DAW application as shown in FIG.

  In the pan / volume adjustment screen, the up / down direction corresponds to the volume of the mixing, and the left / right direction corresponds to the left / right position of the pan (localization) in mixing. When the user B places the NFC tag 18 on the touch display of the tablet PC 21, the NFC tag 18 is close to the NFC reader / writer of the tablet PC 21, so the data stored in the NFC tag 18 by the NFC reader / writer of the tablet PC 21 Is read. Based on the identification data of the NFC tag 18 included in the data read from the NFC tag 18, the tablet PC 21 specifies a track to which the electric base 17 that is a device corresponding to the NFC tag 18 is assigned in the DAW. The tablet PC 21 displays, for example, a device name “Electric Base” corresponding to the NFC tag 18 placed on the touch display on the pan / volume adjustment screen, and “Track #” indicating the DAW track to which the electric base 17 is assigned. "#" Is displayed.

  Subsequently, the tablet PC 21 specifies the position where the NFC tag 18 is in contact with the touch display. The tablet PC 21 sets the volume according to the vertical position on the touch display with which the NFC tag 18 is in contact as the volume of the track of the electric base 17, and according to the left and right position on the touch display with which the NFC tag 18 is in contact. The pan is set as the pan of the electric bass 17 track.

  When the position of the NFC tag 18 is changed on the touch display, the tablet PC 21 sets the volume and pan corresponding to the changed position in the track of the electric base 17. Therefore, for example, the user B slides the NFC tag 18 up and down and left and right on the touch display of the tablet PC 21 while reproducing the performance sound of the band recorded in the DAW, for example. The volume and pan can be adjusted freely. The tablet PC 21 includes a display (touch display) with an integrated touch panel, but the touch panel may be connected to the tablet PC main body as an external device. In that case, the user can instruct the tablet PC main body to adjust the volume by sliding the NFC tag on the external touch panel.

  The tablet PC 21 recognizes, as the NFC tag 18, the pointer that first touched the touch display of the tablet PC 21 after the NFC reader / writer of the tablet PC 21 reads the identification data of the NFC tag 18 from the NFC tag 18, for example. Even if a plurality of pointers are in contact with the touch display, it is possible to specify which of them is the NFC tag 18. However, the method in which the tablet PC 21 recognizes which NFC tag is the pointer that is touched by the touch display is based on the time difference between the timing at which the identification data is read from the NFC tag and the timing at which the pointer contact with the touch display is detected. For example, a method based on a distance difference between the position of the NFC tag estimated by the intensity of the radio wave received from the NFC tag by the NFC reader / writer and the position of the pointer detected on the touch display, etc. Other methods may be employed.

(9) In the above-described embodiment or its modification, a screen that is supposed to be displayed on the touch display of the tablet PC 21 may be displayed on the display 1107 of the audio smart box 11. Further, in the above-described embodiment or its modification, a screen that is displayed on the display 1107 of the audio smart box 11 may be displayed on the touch display of the tablet PC 21.

  Further, the display 1107 included in the audio smart box 11 is a touch display including a touch panel (position specifying means), and the user touches the display 1107 of the audio smart box 11 instead of the tablet PC 21 in the above-described modification (8). The audio smart box 11 may be configured to determine the content of processing for sound waveform data input from a device corresponding to the NFC tag according to the position of the NFC tag. In this case, the audio smart box 11 displays a screen as shown in FIG. 12 on the display 1107, for example, and the user slides the NFC tag 18 on the display 1107, for example. The audio smart box 11 sets the volume and pan corresponding to the position of the NFC tag 18 on the display 1107 to the DAW track to which the electric base 17 that is a device corresponding to the NFC tag 18 is assigned. As a result, the volume and pan in the mixing of the sound waveform data input from the electric base 17 to the audio smart box 11 are changed by the slide operation of the NFC tag 18 by the user.

(10) In the above-described embodiment, the example in which the tablet PC 21 incorporating the NFC reader / writer is used as the terminal device has been described. However, in addition to or instead of the tablet PC 21, an external device is attached to the tablet PC main body. A configuration in which an NFC reader / writer is connected may be employed. Moreover, the form of the terminal device is not limited to the tablet PC, and may be other forms such as a smartphone, a notebook PC, a desktop PC, and the like.
