Abstract
In the process of learning physics, experiments are needed that can help someone in gaining a deeper understanding of learning physics concepts and using technology in the learning process, especially learning sound waves. In this study, the aim is to be able to analyze the sound frequency with the help of Audacity software. Subjects used are 5 different cat sounds. The implementation of this research uses several tools such as a microphone, Audacity software on a laptop, and 5 cat sounds. This experiment was carried out by bringing the micro hope closer to the cat with 5 cm so that the sound was captured by the microphone which would later be transferred to the laptop and read by the audacity software. Furthermore, the data recorded in audacity were analyzed. From the results of the study, it can be said that a tool that can be used in practicum and can read and capture sound waves is effectively used in analyzing sound frequency, spectrum in the application of sound learning so that it can be used as one of the learning media in practicum on sound wave material at Junior high school.
Highlights
Halliday (2002) states that waves are vibrational energy vines that can propagate through the medium or without going through the medium

Novikarany (2010) research how to measure the speed of sound waves in the air based on microcontrollers obtained that automatically by conducting performance tests where all data obtained is processed using a microcontroller and the results are displayed in the form of LCD with sound wave values in the air in the medium of organa pipes with varying frequency values
Summary
Halliday (2002) states that waves are vibrational energy vines that can propagate through the medium or without going through the medium. Novikarany (2010) research how to measure the speed of sound waves in the air based on microcontrollers obtained that automatically by conducting performance tests where all data obtained is processed using a microcontroller and the results are displayed in the form of LCD with sound wave values in the air in the medium of organa pipes with varying frequency values. Especially in the learning process, are needed as a learning medium that plays an important role in the success of the learning process in schools, especially independent learning that is driven by education The existence of this experiment will make students better able to understand the concept of physics learning given especially in this sound wave material with an experiment or simple experiment by utilizing existing media. This article can be used in generating a practicum by using applications in everyday life
