// This sub-API supports the following functionalities:
//
// - Long-term speech and noise level metrics.
// - Long-term echo metric statistics.
// - Round Trip Time (RTT) statistics.
// - Dead-or-Alive connection summary.
// - Generation of call reports to text files.
//
// Usage example, omitting error checking:
//
// using namespace webrtc;
// VoiceEngine* voe = VoiceEngine::Create();
// VoEBase* base = VoEBase::GetInterface(voe);
// VoECallReport report = VoECallReport::GetInterface(voe);
// base->Init();
// LevelStatistics stats;
// report->GetSpeechAndNoiseSummary(stats);
// ...
// base->Terminate();
// base->Release();
// report->Release();
// VoiceEngine::Delete(voe);
