有确实存在的音频会话API可以配置一些SoundProcessing（包括回声消除）。然而，A股OS的iOS设备上的通话过程中，音频会话是考虑到手机的应用程序，因此，所有的音频和音频控制能力从应用中拿走了，你有过任何它没有控制权。

There do exist Audio Session APIs to configure some of the SoundProcessing (including echo cancellation). However, during a phone call on a stock OS iOS device, the audio session is given to the Phone app, and thus all audio and audio control capability is taken away from your app, you have no control over any of it.
