How to use:
1. Install and open the app, then allow microphone access so measurements work correctly.
2. On the home screen, choose a tool. Use Level Meter to measure dB and SPL, Spectrum to view frequencies, or Generator to output test tones or pink noise.
3. Point the microphone toward the sound source and start measuring. Watch real time values and graphs, use hold or reset to capture peaks, and tap save to keep snapshots or logs.
4. For higher accuracy, open Settings to run calibration with a known reference level or select the profile of your external microphone.
5. Export results as images or data, and customize options such as weighting, response speed, and graph scale to fit studio, classroom, or live sound scenarios.
