Abstract

[Problem] To provide an audio processing device that can apply high-load effects in cooperation with an external audio processing device. [Solution] In a karaoke system in which an external amplifier, which is an audio processing device, and a karaoke machine, which is an external audio device, are connected, the external amplifier accepts the setting of effects to be applied to the acquired microphone sound, acquires the microphone sound, and determines that an effect request is made if the set effect load is greater than the processing capacity of the external amplifier, requests the connected karaoke machine to process some of the specified effects, and processes the rest as internal effects within the external amplifier.

Description

This invention relates to an acoustic processing device and an external acoustic processing device used in connection with the acoustic processing device. The karaoke device described in Patent Document 1 has a mixing amplifier connected as an external device. The mixing amplifier mixes the playback signal output from the karaoke device (commander) with the audio from the microphone and outputs it to the speaker. By connecting the mixing amplifier in this way, the karaoke device described in Patent Document 1 is able to mix the audio from the microphone with the playback signal from the karaoke device and output it from the speaker. Japanese Patent Publication No. 2011-237599 Diagram showing the configuration of the karaoke system of this embodiment.This figure shows an example of effect settings in this embodiment.This figure shows an example of the effect settings screen in this embodiment.Flowchart showing the external amplifier coordination process performed by the external amplifier in this embodiment.Flowchart showing the karaoke device coordination process performed by the karaoke device of this embodiment.Flowchart showing the external amplifier-only processing performed by the external amplifier in this embodiment.Flowchart showing the karaoke device-only processing performed by the karaoke device of this embodiment. Figure 1 shows the configuration of the karaoke system in this embodiment. The karaoke system in this embodiment consists of a karaoke device 2 (sometimes called a commander), a remote control device 1, and an external amplifier 5. In this embodiment, the karaoke device 2 and the remote control device 1 are connected to a LAN 100 via wired or wireless communication, forming a network. Furthermore, the karaoke device 2 and the external amplifier 5 are connected via a cable, enabling them to exchange various information, such as sound signals. The karaoke device 2 is equipped with an audio control unit 25 that plays music (accompaniment). In this embodiment, the audio control unit 25 is connected to an external input terminal 25a, which can connect various sound sources such as a microphone 43, and a speaker connection terminal 25b, which can connect a speaker 42 as an external output. In Figure 1, an external amplifier 5 is connected to the karaoke device 2, so the external input terminal 25a and speaker connection terminal 25b are empty. The sound control unit 25 is capable of performing performance processing to reproduce the performance information contained in the music information. Furthermore, the sound control unit 25 is capable of performing effect processing to apply various effects to the sound signal input from the external input terminal 25a or the external amplifier 5, or to the performance sound reproduced by the sound control unit 25. It is also capable of performing mixing processing to mix the performance sound produced by the performance processing with the sound signal input from the external input terminal with added effects, and outputting the result from the speaker connection terminal 25b. Note that in Figure 1, the speaker 42 is shown as a single unit for convenience, but it is possible to use multiple speakers 42 and employ various configurations such as stereo output or surround output. The karaoke device 2 of this embodiment is configured by connecting various devices via interfaces 22a to 22d. While Figure 1 shows the use of four interfaces 22a to 22d, the configuration of interfaces 22a to 22d can be varied; for example, using a single interface or providing one for each device. The karaoke device 2 includes an operation unit 21 that receives various inputs from the user. The karaoke device 2 also includes a hard disk 32 as a storage unit for storing various information. The karaoke device 2 includes a LAN communication unit 24a as a communication means for connecting to the LAN 100 and joining the network. Furthermore, the karaoke device 2 of this embodiment also includes a wireless LAN communication unit 24b, allowing for wireless network connection using the wireless LAN communication unit 24b instead of wired network connection using the LAN communication unit 24a. Furthermore, the karaoke device 2 includes a video playback unit that displays lyrics and background images on the monitor 41. The video playback unit comprises a GPU 29 (Graphics Processing Unit) that forms images based on various information, a RAM 28 that stores information necessary for image formation, and a video output unit 31 that outputs the played-back images to the monitor 41 and the touch panel monitor 33. Furthermore, in addition to the externally connected monitor 41, this karaoke device 2 is also capable of displaying various information on a touch panel monitor 33. The touch panel monitor 33 consists of a display unit 35 that displays video input from the video output unit 31, and a touch panel 34 that outputs the touch input position to the interface 22b.
