如何从AurioTouch项目获取音频数据？

Question

我正在建立一个新的对讲机应用程序，我想从麦克风获取数据我使用这个项目AurioTouch

我在ioData中找到了麦克风捕获的音频数据

可以将* ioData：UnsafeMutablePointer <AudioBufferList> *转换为NSData并通过WebSocket发送它

// Render callback function
func performRender(_ ioActionFlags: UnsafeMutablePointer<AudioUnitRenderActionFlags>,
                   inTimeStamp: UnsafePointer<AudioTimeStamp>,
                   inBufNumber: UInt32,
                   inNumberFrames: UInt32,
                   ioData: UnsafeMutablePointer<AudioBufferList>) -> OSStatus
{
    // we are calling AudioUnitRender on the input bus of AURemoteIO
    // this will store the audio data captured by the microphone in ioData
    let err: OSStatus = AudioUnitRender(_rioUnit!, ioActionFlags, inTimeStamp, 1, inNumberFrames, ioData)
    return err;
}
