@Engineer Thank you for your response. We have two more question. What is the best practice to get decibel audio from microphone? You suggested inputGain to get audio gain from microphone. However it looks the api to get the settings of microphone. We hope to get audio level that input from microphone. Do you have any ideas? About AVAudioRecorder We can find some sample using AVAudioRecorder to get audio gain. Can we use it on the case of streaming? Can we use it with AudioOutputUnitStart? Best Regards.

Are you calling ~Sample before the 2 seconds have passed? No. ~Sample is not called. the actual code is too.

@eskimo , thank you for your response. best practice is to ship your SDK as an XCFramework, and that has a well-documented path forward. I have a question about your statement. I have guessed that the apps including that xc/framework having no code signing or no PrivacyInfo.xcprivacy would be rejected from upcoming April. is this correct?

Thank you for your response, @eskimo What we want to do is that it makes the old version framework customers are still using conform to Apple Privacy. The old versioned that is completely different from the latest one has been supplied as only the .framework. As your response, there is no choice but to make the xcframework because we supply only SDK. I guess PrivacyInfo.xcprivacy is too.
