论文摘要
在现代音频系统中，实时数字信号处理算法被广泛用于各种应用。使用简单的电子电路进行各种研究项目的可能性表现出了巨大的潜力，并逐渐吸引了研究人员和工程师的关注。这项贡献描述了在博士学位论文框架框架中使用的董事会的设计，该论文的主题以对扬声器非线性的实时校正为中心。这项工作中选择的解决方案基于Teensy 3.6微控制器，该微控制器易于使用Arduino IDE和Teensy提供的库进行编程。提供了两种解决方案：一个在市场上提供一个音频板，另一个带有自制板。两种解决方案都包含两个输入和至少一个输出（所有16位）。此贡献并未详细详细介绍与扬声器非线性相关的补偿算法，而是重点介绍董事会设计，比较拟议的解决方案，并提供了基本代码来执行实时数字信号处理。
In modern audio systems, real-time digital signal processing algorithms are widely used for a variety of applications. The possibility of using a simple electronic circuit for variety of research projects has shown remarkable potential and is gradually attracting more and more attention from researchers and engineers. This contribution describes a design of such a board used in the framework of a PhD thesis whose subject is centred on the real-time correction of loudspeaker nonlinearities. The solution chosen in this work is based on a Teensy 3.6 microcontroller which is easy to program using the Arduino IDE and the libraries provided by Teensy. Two solutions are provided : one with an Audio board available on the market and another with a homemade board. Both solutions contain two inputs and at least one output (all 16 bits). This contribution does not detail the compensation algorithm related to the loudspeaker nonlinearities but focuses on the boards design, comparison of proposed solutions, and provides the basic codes to perform the real-time digital signal processing.
