Sound Analysis

March 2, 2024 ยท View on GitHub

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 project

To run the application do the following steps:

  • Make sure to be in the root directory of the project
  • Clean and build the project, run the command:
mvn install

This will also generate a jar file with all the dependencies which we will run once it has been created.

  • 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

Functionality

Analysis in time domain:

  • amplitude chart
  • volume chart
  • short time energy chart
  • zero crossing rate chart
  • silence/voiceless speech/voiced speech

Analysis in frequency domain:

  • frequency chart
  • frequency spectrum chart
  • base tone chart

Clip parameters:

  • volume
  • volume dynamic range
  • average short time energy
  • low short time energy ratio
  • high zero crossing rate ratio
  • standard deviation of the zcr
  • music/speech recognition
