Here is the full list of the supported technologies:

Win32 API:

• Audio Compression Manager ( ACM )
• WaveAPI

DirectX:

• DirectShow
• Direct Media Objects ( DMO )

Intel:

• Intel MMX
• Intel Performance Primitives ( IPP )

The library includes Wave Player, Wave Logger with compression capabilities, DirectShow Audio Player and Audio Logger, Signal and Noise generators, graphic equalizer, audio mixer, multiplier, convertors, spectrum component, channel splitter and merger, a Win32 API and DirectShow Audio Capture components, a Win32 API and DirectShow Audio Playback components. Three additional components from the SignalLab have been added to allow processing Spectrum Data.

AudioLab comes in 3 versions a VCL - Delphi / C++ Builder version, MFC compatible Visual C++, and .NET 2.0-4.0 version, compatible with Visual Studio 2010, Visual Basic.NET, C# and J#.

The Delphi / C++ Builder version is a set of native VCL components.

The Visual C++ version is a set of native Visual C++ classes (components).

The .NET 2.0-4.0 version is a set of managed .NET components.  The .NET version has the same performance as the native versions, and supports all the Microsoft .NET languages including Visual Basic, C#, J# and C++/CLI.

Due to its unique design, AudioLab is implemented the same way in Managed .NET and Win32 environments. The code to control the component from VB.NET, C++/CLI, C#, and J#, Visual C++ MFC, Delphi, and C++ Builder is almost identical. This allows the developers to migrate and share code between the different environments thus significantly improving the productivity.

AudioLab: for fast, complex audio processing with almost zero lines of code!

What can I build with AudioLab?

With AudioLab you can do just about anything imaginable: synthesize, capture, process, and analyze; mix, listen, visualize and more. 

 

Applications include: real time data acquisition, communications, process control, artificial intelligence, signal analysis, digital signal analysis, audio analysis, data visualization, visual instrumentation and more.

 

 

Play recorded audio (see .NET or VCL tutorial):

 

Capture and record audio (see .NET or VCL tutorial): 

 

 

 

Capture, process and record audio:

 

 

Play or capture, analyze the audio, and display the results:

 

 

Mix different audio sources, record and listen to the result:

 

 

 

 

The latest version of AudioLab supports the older Win32 API ( WaveAPI, Audio ACM ), the newer DirectShow and DMO; and allows, if needed, any mixture of these technologies. The developer can choose the technology and can switch from one to the other at any moment: AudioLab hides the complexity of the chosen technology and makes the components look almost identical from the developer's perspective.
