What are the general methods and APIs (preferably for C or C++) for capturing audio input from multitrack mixers/devices? 捕获多轨混音器/设备的音频输入的通用方法和API（最好是C或C ++）是什么？ (Ie an Mbox). （即Mbox）。

So for example, say I have a guitar, bass, trumpet etc. connected to a mixer that is connected to my computer via USB/FireWire, is there an API or general method for getting that input? 例如，假设我有一个吉他，贝斯，小号等连接到通过USB / FireWire连接到计算机的调音台，是否有API或获取该输入的通用方法？

The API is called CoreAudio. 该API称为CoreAudio。 You might have noticed that "CoreAudio" was listed as being supported on that MBox you mentioned, though any class compliant device will be supported on OS X. There are also libraries built on top of CoreAudio that make CoreAudio even easier and/or more portable to work with, such as PortAudio and RTAdudio. 您可能已经注意到，您提到的MBox上列出了“ CoreAudio”受支持，尽管OS X将支持任何兼容类的设备。CoreCore之上还建立了一些库，这些库使CoreAudio更加轻松和/或更便携。与之配合使用，例如PortAudio和RTAdudio。
