-// This sub-API supports the following functionalities:
-//
-//  - Speaker volume controls.
-//  - Microphone volume control.
-//  - Non-linear speech level control.
-//  - Mute functions.
-//  - Additional stereo scaling methods.
-//
-// Usage example, omitting error checking:
-//
-//  using namespace webrtc;
-//  VoiceEngine* voe = VoiceEngine::Create();
-//  VoEBase* base = VoEBase::GetInterface(voe);
-//  VoEVolumeControl* volume  = VoEVolumeControl::GetInterface(voe);
-//  base->Init();
-//  int ch = base->CreateChannel();
-//  ...
-//  volume->SetInputMute(ch, true);
-//  ...
-//  base->DeleteChannel(ch);
-//  base->Terminate();
-//  base->Release();
-//  volume->Release();
-//  VoiceEngine::Delete(voe);
