DirectX Audio Compressor/Limiter from VB 1

[BriansBrain]

To Control the DirectX Audio Compressor/Limiter from VB.
I have a Sound Blaster Live! Audio card therefore I can play
more than one mp3 or and wav at the same time.
What I would Like to do is send ALL files that are played on
the system through the DirectX Audio Compressor/Limiter.
Any One ?

I am not sure I understand your question. Are you asking for a suggestion for a compression limiter that will work with wav and mp3 that may or may not be mixed? Or are you asking how do design a compression limiter?

If you are asking for a suggestion for a compression limiter, there is no promoting, selling or recruiting allowed on this forum. However, there are may fine items to choose from using your search engine.

Sorry if my question was misleading.
I am just asking if anyone knows how to access/control the DirectX Audio Compressor / Limiter from Visual Basic ?

I play about with Visual Basic and music files, a Compressor / Limiter would be good to mess around with.

That was it realy ....... anyone know?

If you installed DirectX SDK, you would have some Filter concerning Audio processing.

The simplest way to get some feeling about what you can do with DirectX SDK on media processing is using GraphEdit.exe, a utility in DirectX SDK. You can directly render a media file with it, eg, .mp3.

Also, DirectX SDK provide you not only filters for playing Audio but also compressing Audio. For example, "MPEG Layer-3" Filter is doing audio compression.

When you feel comfortable with FilterGraph, you can try to play around with them in VB by using "Active control type library". In that case, you will need to make your own filter graph. MSDN Library have detail documentation about the usage.

You may take my program as a reference. It is available at
