WaveFileManipulator is an open source .NET .wav file manipulation library written by David Klempfner

Features

• Reverse the audio
• Get the metadata into a handy model
• Use your own implementations

Metadata

The metadata model includes the following:

• All canonical/standard .wav file format values
• Non standard INFO text segments
• Public constants so you know the start index for sections within the metadata

Info

• You can see the INFO tags and values in the Metadata.Info property
• For more information about what these tags mean, see https://www.recordingblogs.com/wiki/list-chunk-of-a-wave-file

NuGet Package

• This is available as a NuGet package: https://www.nuget.org/packages/WaveFileManipulator/

Your Own Implementation

Want to try a different array reversing algorithm? You can pass in your own implementation of IReverser into the Manipulator ctor.

Examples

• Reverse the audio

using System.IO;
using WaveFileManipulator;

class Program
{
    static void Main(string[] args)
    {
        var filePath = @"C:\File.wav";
        var manipulator = new Manipulator(filePath);
        var reversedByteArray = manipulator.Reverse();
        using (FileStream reversedFileStream = new FileStream(@"C:\ReversedFile.wav", FileMode.Create, FileAccess.Write, FileShare.Write))
        {
            reversedFileStream.Write(reversedByteArray, 0, reversedByteArray.Length);
        }
    }
}

• View the metadata, given a byte array

using WaveFileManipulator;

class Program
{
    static void Main(string[] args)
    {
        byte[] byteArray = GetBytesFromWaveFile();
        var metadata = new Metadata(byteArray);
    }
}

• View the metadata, given a file path

using WaveFileManipulator;

class Program
{
    static void Main(string[] args)
    {
        var filePath = @"C:\File.wav";
        var manipulator = new Manipulator(filePath);
        var metadata = manipulator.Metadata;        
    }
}

• Find the start index of a chunk

using WaveFileManipulator;

class Program
{
    static void Main(string[] args)
    {
        var audioFormatStartIndex = AudioFormat.StartIndex;    
    }
}

• Get the expected value of a section

using WaveFileManipulator;
public class Program
{
    static void Main(string[] args)
    {
        var filePath = @"C:\File.wav";
        var manipulator = new Manipulator(filePath);
        var expectedChunkIdValue = manipulator.Metadata.ChunkId.ExpectedValue; //ChunkId should be "RIFF".        
    }
}

• Find out if the value of a section is expected

using WaveFileManipulator;
public class Program
{
    static void Main(string[] args)
    {
        var filePath = @"C:\File.wav";
        var manipulator = new Manipulator(filePath);        
        var isChunkIdRiff = manipulator.Metadata.ChunkId.IsValueExpected; 
    }
}
