OSX Audio：在我自己的应用程序中使用 Garage Band 插件
我正在为 Mac 编写一个小应用程序，其中涉及录制声音。 在 GarageBand 和 Logic 中，有一个名为“语音增强器”的插件。 有什么方法可以利用这个插件，为那些安装了 GB 或 Logic 的用户提供舒适的噪音消除功能并均衡 Mac 的内置麦克风吗？ 该插件没有出现在 AULab 中，所以我希望它是 Apple 独有的东西（顺便说一句，这太离谱了）。 有什么建议么？ 谢谢 沙克连
I'm writing a little app for the Mac, that involves recording a voice.
In GarageBand, and in Logic for that matter, there is a plug-in called Speech Enhancer.
Is there any way I can piggyback on this plug-in, offering those users that have GB or Logic installed the comfort of noise cancellation and equalizing the built-in mike of their Mac?
The plug-in doesn't show up in the AULab, so I expect it to be an exclusive Apple-thingy (which is outrageous by the way).
Any suggestions?
Thanks

Garage Band 和 Logic 中的 AudioUnit 插件是这些程序独有的，不能在其他主机中使用，正如您所怀疑的那样。 但是，有很多很棒的第三方插件，您可以使用它们来实现相同的效果...只需在 KVR 音频插件数据库。 您也许能够找到一个很好的免费软件插件来完成您想要的功能，或者您可以与开发人员达成协议，在您的应用程序中重新分发插件。
另外，您应该记住，虽然有很多声音处理插件，但您也可以使用由其他几种效果构建的效果链来构建自己的插件。 例如，通过链接降噪器、均衡器、立体声增强器、混响器和压缩器，通常可以获得相当好的效果。 这篇不错的和谐中心文章中有更多建议，或者直接谷歌一下用于“录音室声音处理”（或其某些变体）。
The AudioUnit plugins in both Garage Band and Logic are exclusive to those programs and can't be used in other hosts, as you had suspected. However, there are plenty of great third-party plugins out there which you could use to achieve the same effect... just do a search over at the KVR Audio plugin database. You might be able to find a nice freeware plugin that does what you want, or you could possibly cut a deal with a developer to redistribute a plugin with your app.
Also, you should keep in mind that while there are plenty of vocal processing plugins out there, you can also brew your own with an effect chain built from several other effects. For instance, you can generally get pretty good results by chaining up a noise reducer, EQ, stereo enhancer, reverb, and compressor. There are some more suggestions in this nice harmony central article, or just google for "studio vocal processing" (or some variation thereof).
AudioUnit 接口是 Core Audio 框架的一部分。 Developer CoreAudio 示例文件夹中有一个 AudioUnit 主机应用程序示例。
