Why Monitor Microphone and Audio Usage?

1. Privacy Protection: Prevent unauthorized eavesdropping or recording.

2. Security: Detect malicious apps or malware accessing your microphone.

3. Resource Management: Identify apps using audio devices unnecessarily, saving battery or processing power.

4. Troubleshooting: Diagnose audio input/output problems by monitoring usage.
