Question

如何将iPhone的麦克风中的音频流式传输到Mac / PC？是否已有一些框架，或者我可以通过套接字发送音频。我虽然是新的插座。基本上，我希望能够对着iPhone说话，并且计算机将接收iPhone的麦克风输入作为自己的麦克风输入，用于没有麦克风的计算机。我已经有一个应用程序与Mac连接，它运行一个非常简单的服务器，iPhone可以将文本发送到计算机，但iPhone如何从麦克风发送音频，现场音频到它？

您需要AVCaptureSession和AVCaptureDevice的组合才能从麦克风中读取 - 请参阅AV Foundation编程指南。 http://developer.apple.com/library/ios/#DOCUMENTATION/AVFoundation/Reference/AVCaptureAudioDataOutput_Class/Reference/Reference.html#//apple_ref/occ/cl/AVCaptureAudioDataOutput

链接使用sokets

@interface Client : NSObject {
    NSInputStream *_inputStream;
    NSOutputStream *_outputStream;
}

@implementation Client

- (void)initNetworkCommunication {
    CFReadStreamRef readStream;
    CFWriteStreamRef writeStream;
    CFStreamCreatePairWithSocketToHost(NULL, (CFStringRef)@"localhost", 50000, &readStream, &writeStream);

    _inputStream = (__bridge NSInputStream *)readStream;
    _outputStream = (__bridge NSOutputStream *)writeStream;

    [_inputStream setDelegate:self];
    [_outputStream setDelegate:self];

    [_inputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];
    [_outputStream scheduleInRunLoop:[NSRunLoop currentRunLoop] forMode:NSDefaultRunLoopMode];

    [_inputStream open];
    [_outputStream open];
}

// send data to server


- (IBAction)onSendButtonTapped:(id)sender {
    NSString *command = self.commandField.text;
    NSData *data = [[NSData alloc] initWithData:[command dataUsingEncoding:NSUTF8StringEncoding]];
    [_outputStream write:[data bytes] maxLength:[data length]];
}

如何通过套接字或框架将音频从iPhone的麦克风传输到Mac / PC？
