Description

  The present invention relates to an audio device editing apparatus that can easily set sound in a small-scale audio facility.

  Small mixers are used as audio equipment for small venues such as public halls and hotels. For users of audio equipment, “contractors” who have high skills in operation of audio equipment and the acoustic equipment they have compared to contractors such as hall managers and Nakai-san in the banquet hall There are “end users” who have relatively low skills to operate equipment. For example, when setting a mixer so that it can be used at a lecture, etc., connect a stage microphone to the stage center microphone outlet, set the speaker microphone, and connect the line from there to the corresponding channel of the mixer with a cable. After that, parameter values such as head amplifier (HA), equalizer (EQ), fader, suppressor are set, and output bus assignments are adjusted. Furthermore, when a moderator microphone is required in addition to the speaker microphone, the same setting as the speaker microphone is made for the moderator microphone. These tasks require specialized knowledge and skills.

In addition, when the moderator microphone is not good, the moderator microphone is connected to a poor microphone outlet that is prepared separately from the stage center microphone outlet. It is necessary to select a channel that is not connected and connect it. Even in the current situation, if you use a large mixer with a sufficient number of inputs, set a dedicated parameter value for each channel and use it with the appropriate settings by connecting a microphone for that channel to that channel. However, it is impractical to use a large mixer for small-scale equipment due to installation space and cost.
By the way, if a digital mixer is used as a mixer, it is possible to store dedicated settings for each application in advance as a library and call up the parameter set from the library as appropriate (see Non-Patent Document 1). However, in order to do so, knowledge and skills of mixer operation sufficient for the operation are required.

The chip ID of each chip 20 is associated with designation information for designating a “preset name to be used”, and each “preset name to be used” is associated with a parameter set including a plurality of parameter values. A library of at least one (preferably plural) parameter set is stored on the memory 11. FIG. 4A shows a table of chip IDs associated with the mixer 1 according to the embodiment of the present invention and designation information for designating “preset names to be used”, which are associated with “preset names to be used”. A parameter set library is shown in FIG.
The table shown in FIG. 4A and the library shown in FIG. 4B are set in advance by the contractor and stored in the memory 11. In the case shown in FIG. 4A, the chip 20 with the chip ID “# 1” is associated with designation information that designates a parameter set corresponding to “preset name to be used” that is “speaker microphone”.

Used are connected to the I / O # 1 as shown in FIG. , Microphones 41b,... Are connected to I / O # 2, and these I / O # 1 and # 2 are connected to mixer 1 ′. In this case, the memory 11 of the mixer 1 stores the table and library shown in FIGS. 7A and 7B by the contractor. Then, the chip 20 corresponding to the preset used in the channel is selected and placed on the leader section 2c of any channel strip in the mixer 1. For example, it is assumed that the chip 20 displayed as “Lecturer microphone” is selected and placed on the reader unit 2c. When the reader unit 2c detects that the chip 20 is placed and reads the chip ID of the placed chip 20, the CPU 10 starts the preset application process 2 shown in FIG. When the preset application process 2 is started, the CPU 10 reads the chip ID of the chip 20 placed on the reader unit 2c in step S20. Next, in step S21, the CPU 10 shows the port information of the I / O box to be used and the port number to be used from the second designation information and the third designation information associated with the chip ID, as shown in FIG.
