Lack of advanced measurement options (e.g. LUFS measurement)

Sound Level Meter Application. This application utilizes the microphone to measure sound levels and translates this into a Sound Pressure Level (SPL) value. FOR REFERENCE ONLY. The accuracy of the results is influenced by the device and its hardware capabilities. Some devices may have a measurement range as limited as 20 dB, while others could exceed 100 dB.

This SPL meter offers several features:

Analog Dial with maximum and minimum reading indicators.

Weighting options – A, C, or None. (A weighting adjusts for higher and lower frequencies based on human perception of loudness). Readings are available in dB, dBA, or dBC depending on the chosen weighting.

SPL averaging, along with Clear and Pause functionalities.

Frequency analysis through octaves and third octaves.

Graphical display illustrating the temporal changes in sound.

Autoscale or manual control (pinch & pan) of the Y-Axis.

Relative button – tapping REL will subtract the current averaged value from the displayed readings, aiding in comparing differences.

Calibration feature – If you possess a calibrated SPL meter or a known sound source, this option allows you to adjust the meter accordingly. (Please note this remains for reference only).

Additional technical specifications can be found in the relevant documentation.

Precision at Your Fingertips: My Experience with Sound Level Meter

From the moment I launched Sound Level Meter, I was immediately impressed by its professional‑grade functionality packed into a sleek, user‑friendly interface. The analog dial, complete with maximum and minimum indicators, gave me an intuitive grasp of ambient noise levels, while the A, C, and flat weighting options enabled me to tailor readings in dB, dBA, or dBC to match real‑world auditory perception.

I found the SPL averaging and pause features invaluable for capturing stable measurements during fluctuating soundscapes, and the octave‑based frequency analysis provided deep insight into noise profiles I’d never accessed before. The dynamic graphical display clearly illustrated temporal sound changes, and autoscale—with optional manual pinch‑and‑pan control—ensured every detail stayed in view. By using the REL button, I could instantly compare relative differences, and the calibration tool allowed me to fine‑tune readings against a reference meter for added confidence. While dependent on my device’s microphone, this app has become my go‑to solution for quick, reliable SPL measurements—truly a must‑have for audio enthusiasts and professionals alike.
