I want to develop a VOIP application on Mac OS X.The first,I search for some audio APIs on Mac OS X. Then I found these APIs(or Framework) have the audio capture and playback capabilities:

1.Audio Queues(In the Core Audio Framework of Mac OS X)

2.Audio Units(In the Core Audio Framework of Mac OS X)

3.AVFoundation Framework

4.QTKit Framework

5.....(some APIs that I didn't found)

I'm a noob on Mac OS X ,I don't know which APIs(or framework) is more suitable for developing a VOIP application , Can someone give some suggestion ?

Thanks & Regards.

对于 VOIP，低延迟对可用性很重要。Audio Unit API 将为您的应用提供最低延迟的音频。AVFoundation 和音频队列建立在音频单元之上。
