Core Audio framework

There are several options available for implementing audio or video recording in Objective C apps. One popular method is using the AVFoundation framework provided by Apple, which offers a high level of control and flexibility. Another option is to use third-party libraries such as OpenTok or Twilio, which provide pre-built components for audio and video recording. Additionally, developers can leverage the Core Audio framework for low-level audio recording and processing. Each option has its own advantages and considerations, so it’s important to evaluate your specific project requirements before making a decision.
