iOS 7 multipeer connectivity streaming audio

Question

Does anyone know if it's possible to live stream my iOS device microphone's audio signal to other iOS devices in "real time"? I want to use the multipeer connectivity framework via wifi or Bluetooth.

Thank you

this is how it send and recieve message

SendCallback:

- (IBAction)SendMessage:(id)sender {
  NSString *message = self.tfMessage.text;
  self.tfMessage.text = @"";
  NSData *data = [message dataUsingEncoding:NSUTF8StringEncoding];
  NSError *error;
  [self.Session sendData:data toPeers:[self.Session connectedPeers] withMode:MCSessionSendDataUnreliable error:&error];
  [self receiveMessage: message fromPeer: self.PeerID];
}

ReceiveCallback:

- (void) receiveMessage: (NSString *) message fromPeer: (MCPeerID *) peer{
  NSString *formatedMessage;
  if (peer == self.PeerID) {
    formatedMessage = [NSString stringWithFormat:@"\n%@: %@ \n", peer.displayName, message];
  }else{
    formatedMessage = [NSString stringWithFormat:@"\n%@: %@ \n", peer.displayName, message];
  }
  self.tvMessages.text = [self.tvMessages.text stringByAppendingString:formatedMessage];
}

Init:

self.PeerID = [[MCPeerID alloc] initWithDisplayName:[UIDevice currentDevice].name];
self.Session = [[MCSession alloc] initWithPeer:self.PeerID];
self.Session.delegate = self;
self.browserViewController = [[MCBrowserViewController alloc] initWithServiceType:@"chat" session:self.Session];
self.browserViewController.delegate = self;
self.advertiser = [[MCAdvertiserAssistant alloc] initWithServiceType:@"chat" discoveryInfo:nil session:self.Session];
[self.advertiser start];

Answer 1

Take a look at this code. It seems to use CoreAudio, so you should be able to open the Mic AudioUnit and change the code above slightly.

Use GKVoiceChat, it simply needs some hooks to wire data into. GameKit itself is deprecated in iOS 7, but this tiny little service seems not. Actually it has nothing to do with the rest of GameKit services.
