Known issues

CH08_AUGraphInput

The output can be silent when you use different devices for the input and output. As a workaround, try to change the size of the ring buffer.

CH11_MIDIWifiSource

The MIDIWifiSource crashes on iOS 9 + OS X 10.10. I was unable to test it with different OS's versions.

In case you're interesting in debugging it, the crash happens when the connection is initialized:

let connection = MIDINetworkConnection(host: host)

CH01_CAMetaData - CFDictionaryRef isn't a pointer?

Hi,
using you're first sample code, I had an issue to get the values from the 'kAudioFilePropertyInfoDictionary'

In code line 35, I replaced:

var dictionary: UnsafePointer? = nil

--> var dictionary: CFDictionary? = nil

assuming the value you get from the following code lines is actually a Dictionary of type [String:Any] and not an 'UnsafePointer

theErr = AudioFileGetProperty(audiofile!, kAudioFilePropertyInfoDictionary, &dictionarySize, &dictionary)
assert(theErr == noErr)

   if let audioMetaData = dictionary as? [String:Any] {
    print(audioMetaData)
   }

Output window gives me now:

Printing description of audioMetaData:
▿ Optional<Dictionary<String, Any>>
▿ some : 1 element
▿ 0 : 2 elements
- key : "approximate duration in seconds"
- value : 1.622
Optional(["approximate duration in seconds": 1.622])
Program ended with exit code: 0

Kind regards
Andre

hi my friend.

How do I record my voice with a background song playing?

ı think you solve my problem. because your sample look very nice.

Get audio input buffers and put the output audio into the same buffers as well. i need a player to play the background song and it can mix itself and record it.
will you help me? it can be any PODS or any solution. I need it too much.
