iOS xcode microphone volume detection?
提问by Albert Renshaw
What frameworks are required to detect how loud someone is talking into a microphone... Also, can anyone tell me what to search for in the documentation or google so I can create some code... What line of code would be commonly used when detecting volume levels of noise through the microphone? Thanks!

This seems to be a duplicate of:
这似乎是以下内容的重复：
Realtime microphone sound level monitoring
However, that question is old and the accepted answer links to a deprecated library. They now recommend that you instead use AVAudioRecorder. They suggest this tutorialand it seems to be what you are looking for.
但是，这个问题很旧，接受的答案链接到已弃用的 library。他们现在建议您改为使用AVAudioRecorder. 他们建议本教程，它似乎是您正在寻找的内容。
