MP3 decoder in managed .NET code.

MP3Sharp

Decode MP3 files to PCM bitstreams entirely in .NET managed code:

SETUP

To use MP3Sharp, you will need: an audio device that accepts PCM data, an array of bytes to act as the PCM data buffer (default size is 4096 bytes), and a MP3 file. That's it!

The default interface to MP3Sharp is the MP3Stream class. An instance of MP3Stream takes a filepath to a MP3 file as a parameter and outputs PCM data:

// open the mp3 file.
MP3Stream stream = new MP3Stream(@"sample.mp3");
// Create the buffer.
byte[] buffer = new byte[4096];
// read the entire mp3 file.
int bytesReturned = 1;
int totalBytesRead = 0;
while (bytesReturned > 0)
{
    bytesReturned = stream.Read(buffer, 0, buffer.Length);
    totalBytesRead += bytesReturned;
}
// close the stream after we're done with it.
stream.Close();

So simple!

MP3Sharp is a port of JavaLayer, a MP3 decoder written by JavaZoom and released under the LGPL. JavaLayer was initially ported to C# by Robert Burke, in what he modestly describes as a 'half day project'. tekHedd added some significant speed optimizations. This repository includes bug fixes (fixes for correctly outputting VBR, mono, and ability to loop without crashing; nice!).
