摘要： There is disclosed an audio recorder that automatically determines, when preset microphones are configured to be detachable and different microphones are attached to the same jacks, whether or not the different microphones are in-house microphones, and automatically determines which of the X-Y technique or the A-B technique is used as the attachment technique. Holders in the audio recorder include a switch structure in which, in cases where the different microphones are attached in place of the preset microphones, a contact is turned on only when the different microphones are in-house microphones. Further, a main body unit includes a processor that, when the contact in the switch structure is turned on, automatically determines which of the X-Y technique or the A-B technique is used based on a voltage value of a certain terminal in a plug of the different microphones.

摘要： A recording/reproducing apparatus with a wireless LAN function. The recording/reproducing apparatus has a Wi-Fi module and establishes a Wi-Fi connection with a smartphone, and the like. When the Wi-Fi connection with a smartphone is established, the recording/reproducing apparatus automatically extinguishes a display, thereby curtailing power consumption. In addition, the display is extinguished, and an operating status of the display is transmitted to the smartphone by way of the Wi-Fi connection.

摘要： Disclosed is an apparatus for setting a target position using a GUI screen. The apparatus includes a display that displays a representation of a listener and a representation of a hemispherical dome with the listener at the center as projected on a horizontal plane. A user sets a radius of the hemispherical dome through a click operation of a mouse and sets a target position of a sound image with respect to the listener through a drag operation toward the center. The sound image position is represented by a dot O. The dot O represents a position of the sound image with respect to the listener in the left-to-right direction, in the front-to-rear direction, and in the height direction.

摘要： A multitrack recording system is disclosed. A multitrack recording/reproducing apparatus records a first audio signal with a multitrack recording apparatus into any of a plurality of channels (tracks). In the meantime, a smartphone records a second audio signal as a sound record file into a recording medium. A Wi-Fi connection is established between the sound recording apparatus and the smartphone, and the sound record file is transferred from the smartphone to the recording/reproducing apparatus. The recording/reproducing apparatus stores the sound record file into a remaining channel where the first audio signal is not recorded among the plurality of channels.

摘要： In a recording system comprising a plurality of recording apparatuses connected in cascade to increase the number of audio channels, a desired audio signal can be monitored. In the recording apparatus, when a digital audio signal is input from a digital input terminal and an analog audio signal is input from an analog audio input terminal, the analog audio signal is converted to a digital signal, which is further embedded in the digital audio signal and output from an output terminal. When an operation unit designates a channel to be used for monitor output, among the digital audio signal input from a digital input terminal and a digital audio signal obtained by converting the analog audio signal to the digital signal, an audio signal of the channel which is designated is output for monitoring.

摘要： A control device is provided which mixes and outputs two types of audio signals processed under standards different from each other; in particular, an audio signal of ASIO standard and an audio signal of WDM standard. An audio interface is connected to a computer, and an audio signal is input to the computer. A mixer module of the computer mixes an audio signal which is effect-processed by an ASIO application and an audio signal reproduced by a WDM application, outputs the mixed audio signal to the audio interface, and also outputs the mixed audio signal to the WDM application and records the sound. In each step of the process, double buffering is used to reduce sound drop-out.

摘要： A multi-band limiter, a sound recording apparatus, and a program are provided having a multi-band limit function with a flat frequency characteristic while removing a dead zone of a multi-band limiter. A cross-over filter unit divides an input sound signal into a low-band component, a middle-band component, and a high-band component so that the adjacent bands cross at -6 dB. An overlap filter unit includes a low-band filter element, a middle-band filter element, and a high-band filter element that respectively divide the input sound signal into a low-band component, a middle-band component, and a high-band component, and applies a limit process to divide the input sound signal in such a manner that the low-band component and the middle-band component overlap each other and the middle-band component and the high-band component overlap each other by setting a high-band side cutoff frequency of the low-band filter element to be greater than or equal to a low-band side cutoff frequency of the middle-band filter element and setting a high-band side cutoff frequency of the middle-band filter element to be greater than or equal to a low-band side cutoff frequency of the high-band filter element, and set a control gain by a CG for each band, and an adder combines the components.

摘要： A sound recording apparatus is provided which is HDMI-connected to a camera and another device, which outputs a video image signal from the camera to the other device without processing, and which outputs to the other device, without degradation, an audio signal recorded separately from the camera. A sound recording apparatus is HDMI-connected to a camera and a backup image recording apparatus. The sound recording apparatus includes an HDMI receiver that receives an HDMI signal transmitted from the HDMI-connected camera, a controller that embeds an audio signal which is input from a microphone which is connected to the apparatus in an audio channel portion of the HDMI single, and an HDMI transmitter that outputs to the backup image recording apparatus the video image signal included in the HDMI signal and the audio signal embedded by the controller.

摘要： An audio apparatus includes a controller configured to set one of operation units as a master and another as a slave, and to cooperatively operate the slave operation unit while maintaining the level difference with the master operation unit. When an operation value of one of the operation units reaches the maximum or the minimum, the controller stores a level difference at that point in a memory, temporarily cancels the cooperative operation between the operation unit and the master operation unit, and allows for operation of the master operation unit and an operation unit that has not reached the maximum or the minimum. When the master operation unit is operated in a reverse direction and the level difference between the master operation unit and the operation unit matches the level difference stored in the memory, the controller restores the cooperative operation between the operation unit and the master operation unit.
