About WAV File Format

The WAV (Waveform Audio File Format) is a popular audio file format that is commonly used for storing uncompressed audio data. The format doesn’t apply any compression to the bitstream and stores the audio recordings with different sampling rates and bitrates. It has been and is one of the standard formats for audio CDs.

WAV files are widely supported by audio software and hardware devices, making them a versatile choice for audio recording, editing, and playback.

How To Merge Several WAV Files Into A Single File

The following example demonstrates how to combine multiple audio files with several lines of Java code:

  • Create an instance of the Merger class and pass the source audio file path as a constructor parameter. You may specify absolute or relative file paths as per your requirements.
  • Add another audio file to merge with the join method. Repeat this step for other audio files you want to merge.
  • Call the save method and specify the filename for the resulting audio file as a parameter.
// Load the source WAV file
Merger merger = new Merger("c:\sample1.wav"))
    // Add another WAV file to merge
    // Merge WAV files and save result"c:\merged.wav");
