Description

Sound effect device, audio processing method and storage medium

Technical Field

The present application relates to the field of audio processing technologies, and in particular, to a sound effect device, an audio processing method, and a storage medium.

Background

The sound effect device is an electronic device that processes audio signals output by a stringed instrument in terms of sound characteristics, such as amplitude and frequency, by means of analog circuits or digital signal processing, so as to achieve effects required by a player. The sound effect device can be in various types, such as a floor type, a table type or a rack type. The sound effect device is divided into an analog mode and a digital mode from the mode and the method for realizing the audio processing effect. The main focus here is in the category of digital audio effects. Generally, a digital sound effect device has an audio input/output circuit and at least one arithmetic processor for calculating digital signals and outputting the calculation results, thereby achieving the function of signal processing.

With the development of technology, some audio effects began to appear as network interfaces, including wired ethernet connections, wireless bluetooth or Wi-Fi connections. Typically, these network-interfaced audio effects are interfaced through a network interface to a computer within the network, on which a user-operable application is located. The user operates this application to download the specified files into the memory of the networked sound effects. These files may be an algorithm code to replace the algorithmic portion of the sound effects. It is also possible to have a configuration file for modifying the parameter settings of the present sound effects. The number and size of these files are different, and many times, many different files are needed to implement a single function. This puts certain demands on the storage function of the sound effects. And users also need to frequently replace the files, so that the users need to continuously switch back and forth between the equipment and the computer storing the files so as to realize the function of updating the files. In addition, the existing sound effect device can not autonomously change data required by operation in real time according to the current operation requirement, and completely depends on manual operation of the sound effect device by a user or application software on a computer connected with the sound effect device through a network. This is a limitation to the use and development of increasingly artificial intelligence based, dynamic response and arithmetic sound effect algorithms.
