Sound Analysis

Application to analyze sound files in time or frequency domain.
It uses ffmpeg to turn any audio or video file into raw audio data. Java 8+ is required to run this application.

Prerequisites

Please ensure that you have ffmpeg installed and configured in your $PATH before running this application. To verify the setup, open your terminal and enter the command ffmpeg.

Run the main method in Main.java by running:

mvn exec:java

Alternatively, you can run the main method in Main.java in your chosen IDE, e.g. IntelliJ
