vbMP3Decoder

Original Release: Jan/27/2006
Latest Update: July/15/2010

What is vbMP3Decoder?

Well, as its name suggests, it's an MP3 decoder written in Visual Basic.
The original Visual Basic 6 code is a port from Krister Lagerström's C version of the decoder and it was made by Murphy McCauley from http://www.constantthought.com/

Murphy's original VB6 code worked perfectly and it was able to convert an MP3 file into a WAV file. I then modified the code so that instead of writing the PCM data to a file, it would write it to a DirectSound buffer. Unfortunately, VB6's code was extremely slow -- the CPU resources quickly raised to 100% and the decoder wasn't able to play a single MP3 file without skipping.
Then I decided to port the code to VisualBasic.NET 2005 and see if I could take advantage of the new array handling routines, among other things. After playing a bit with the code I have been to reduce the CPU consumption to less than 15%.
Later on I rewrote a lot of the code to take advantage of the new features in recent versions of the .NET, making it simpler, cleaner and even faster.

What can I use this for?

To learn...
The speed and quality of the decoder are not optimal for a production environment, so I'd suggest you use this code to learn and of course, to admire how VB and the whole .NET framework have evolved!

You can’t perform that action at this time.
