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 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
