Setup and sanity checks

    sound4::bigvoice::SetLogSeverity(verbose5);
    sound4::bigvoice::SetLoggerCallback(MyLogger);
 
    sound4::bigvoice::CInstance instance;
    instance.SetParam("ADMIN_USER","admin");
    instance.SetParam("ADMIN_SECRET","admin");

Sample to create the processing instance

    if (!instance.Create(LoginKey, RadioName, KeyId, AccessKey, store_path)) {
        std::cerr << "Failed to create the processing instance" << std::endl;
        return 1;
    }

Communicating with the instance

jsonsyntax

        auto client = instance.NewClient();
        auto answer = client->ProcessJson(R"JSON({"get":{"processorname":null}})JSON");
        std::cerr << "Request for processor name returned "<<answer<<std::endl;

Starting a web-server

    if (!instance.StartWebServer(listen_port,0)) {
        std::cerr << "Failed to create the web server on port " << listen_port << std::endl;
        return 1;
    }

Sample processing loop

    while (!stopthread)
    {
        // Read a chunk from stdin
        if (std::fread(instance.GetBufferIn().data(), sizeof(float), sound4::bigvoice::InputSampleSize, stdin) != sound4::bigvoice::InputSampleSize) {
            std::cerr << "ProcessLoop: input stopped"<< std::endl;
            stopthread=true;
            break;
        }
        if (stopthread) break;
        // Process it
        instance.ProcessAudio();
        // Write it to stdout
        if (fwrite(instance.GetBufferOut().data(), sizeof(float), sound4::bigvoice::OutputSampleSize, stdout) != sound4::bigvoice::OutputSampleSize) {
            std::cerr << "Failed to write audio output" << std::endl;
            stopthread=true;
        }
    }
