SPL Meter

By leveraging your device’s microphone, it measures decibel levels with real-time analog dials, customizable weighting filters (A/C/None), and graphical trends. While hardware limitations affect absolute accuracy, its intuitive design and features like calibration tools make it a practical choice for quick noise assessments.
