on the client side I have this code

Socket socket = new Socket("10.0.0.10", 7800);
                            ParcelFileDescriptor socketWrapper = ParcelFileDescriptor.fromSocket(socket);
                            mediaRecorder = new MediaRecorder();
                            mediaRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
                            mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
                            mediaRecorder.setAudioEncoder(MediaRecorder.OutputFormat.AMR_NB);
                            mediaRecorder.setOutputFile(socketWrapper.getFileDescriptor());
                            mediaRecorder.prepare();
                            mediaRecorder.start();

How do I send this audio to a C ++ server and re-stream it to others using the app?

Server code

// Iniciarlizar winsock
WSADATA wsData;

    return;

bind(escutando, (sockaddr*)&hint, sizeof(hint));

// Diga ao winsock que o soquete é para ouvir
listen(escutando, SOMAXCONN);

// aguarde uma conexão

sockaddr_in client;
int clientSize = sizeof(client);

SOCKET clientSocket = accept(escutando, (sockaddr*)&client, &clientSize);

char host[NI_MAXHOST];  // Client's remote name

ZeroMemory(host, NI_MAXHOST);
ZeroMemory(service, NI_MAXHOST);

if (getnameinfo((sockaddr*)&client, sizeof(client), host, NI_MAXHOST, service, NI_MAXSERV, 0) == 0)
{
    cout << host << " Conectado na porta " << service << endl;
}
else
{
    inet_ntop(AF_INET, &client.sin_addr, host, NI_MAXHOST);
    cout << host << " Conexão na porta " <<
        ntohs(client.sin_port) << endl;
}

// tomada de escuta próxima
closesocket(escutando);

// while loop: aceita e faz eco da mensagem de volta ao cliente
char buf[4096];
while (true)

    ZeroMemory(buf, 4096);

    // Wait for client to send data
    int bytesReceived = recv(clientSocket, buf, 4096, 0);
    if (bytesReceived == SOCKET_ERROR)

    }

// Feche o soquete
closesocket(clientSocket);

// Desligar winsock
