## Description

The SPL Meter Chrome extension is a powerful tool designed to measure sound pressure levels (SPL) using your device's microphone. It provides accurate SPL readings with selectable A, C, or no weighting filters, emulating how the human ear perceives loudness. Users can view dB, dBA, or dBC values alongside analogue dial visuals with max and min indicators.

Additional features include third octave spectrum displays, time-dependent sound graphs with autoscale and manual zoom options, and flexible averaging controls. The extension also allows calibration against a known SPL source for improved indication accuracy. Ideal for environmental monitoring, audio analysis, and educational purposes, SPL Meter offers a user-friendly interface with clear, reliable sound level insights directly from your browser.

## Review summary

Users appreciate the SPL Meter app's functionality with A and C weighting curves, calibration options, and a simple user interface. The app provides useful features like spectrum display and adjustable settings, with minimal ads that can be removed. However, many users report accuracy issues, especially before calibration, with readings often higher than actual sound levels. The app's reliability varies depending on the device's microphone quality, and some find the interface outdated. It lacks advanced measurements such as true peak and LUFS levels, which limits its professional application.

### Pros

- Includes A and C weighting curves for sound measurement.
- Provides calibration options for more accurate readings.
- Simple and functional user interface, easy to use.
- Offers spectrum display and adjustable time constants for detailed analysis.
- No intrusive ads, with ad removals available via payment.

### Cons

- Accuracy issues out of the box; readings often higher than real SPL levels, requiring calibration.
- Dependent on device hardware; microphone limitations affect measurement reliability.
- Interface can appear outdated and sluggish on newer Android versions.
- Free version includes ads, which some users dislike and can remove by paying.
- Does not measure true peak or LUFS levels, limiting professional use.
