A. 1. Open the BirdNET app and navigate to the settings menu. 2. Look for an option related to microphone sensitivity or audio input settings. 3. Adjust the sensitivity level to a higher or lower setting based on your environment. 4. Test the microphone by recording a short audio clip and playing it back to check if the sensitivity has improved. 5. If the app does not have sensitivity settings, consider using an external microphone with adjustable sensitivity for better results.

B. 1. Ensure that your device's microphone is not obstructed by a case or dirt. 2. Test the microphone using another app (like a voice recorder) to confirm that the issue is not with the device itself. 3. If the microphone works well in other apps, try reinstalling BirdNET to reset its settings.
