From the developer: "ODMMixerTool is a lightweight COM object that can be used to control the inputs/outputs/mutes of a computers sound card(s) lines. Though the use of properties a developer can call one method (Init) then access or set volume levels for lines such as the main line out or the WAV line. This component can be used in any language which can create COM objects such as Visual Basic, Visual C++, or Visual Fox Pro to name a few. The object was written in VC++ 6.0 compiled as a ATL object so it is very small in size and easily redistributable. Source code is also available for purchase."
