iPhone AVAudioRecorder Guide?

Can anyon开发者_高级运维e point me to a tutorial or discussion that provides a clear-cut, full explanation of how to use the AVAudioRecorder method of recording audio in iPhone apps? Although I'm new to iPhone programming in general, I do have a basic understanding and yet all my attempts to use AVAudioRecorder have failed miserable. Much appreciated!

Sample code and documentation can be found here. You can fill in the blanks with searches here on StackOverflow. If you haven't started with Audio, it's best to look at the Apple docs and example code first. Then have a look at other sources. This is where a good book on iPhone development comes in.

To use AVAudioRecorder you first need to enable the AVAudioSession and init and start AVAudioRecorder, here's my example of how to set everything up and measure the level of "loudness" for instance http://www.mikitamanko.com/blog/2017/04/15/swift-how-to-get-decibels/
