Abstract 
In the field of digital signal processing, with the advancement of science and technology and the growing demand for data processing, efficient and accurate tools have become a key factor to promote the development of research and application. As a powerful mathematical software, MATLAB, with its rich functions and flexible programming environment, plays an important role in the development and application of digital signal processing tools. This paper aims to discuss the development process of digital signal processing tool based on MATLAB and its effect in practical application, in order to provide reference for researchers and developers in related fields. In the development process of digital signal processing tools, MATLAB provides developers with rich tools and resources by virtue of its powerful numerical calculation, graphics processing and algorithm development capabilities. Through MATLAB, developers can quickly build digital signal processing models to achieve signal acquisition, processing, analysis and visualization. At the same time, MATLAB also provides a wealth of function libraries and toolboxes, such as signal processing toolbox, communication system toolbox, etc. These tools greatly simplify the development process and improve the development efficiency. In the application of digital signal processing tools, tools based on MATLAB have a wide range of application scenarios. In the field of communication, these tools can be used in signal modulation, demodulation, encoding, decoding and other processing processes to achieve efficient and reliable data transmission. In the field of image processing, these tools can be used in image filtering, enhancement, segmentation and other processing processes to improve image quality and readability. In the field of audio processing, these tools can be used for noise reduction, compression, recognition and other processing processes of audio signals to improve the clarity and intelligibility of audio signals. Digital signal processing tools based on MATLAB are also highly customizable and extensible. Developers can customize and develop specific signal processing algorithms and models according to specific needs to meet the needs of specific application scenarios. At the same time, MATLAB also supports integration with other programming languages and tools, which makes it easy for developers to embed MATLAB tools into larger systems and achieve a wider range of applications. Digital signal processing tools based on MATLAB have significant advantages in development and application. Through MATLAB, developers can quickly build efficient and accurate digital signal processing tools, providing strong support for research and application in the field of digital signal processing.
