SPL Meter
An analog-style sound-level display with A or C weighting, Fast or Slow response and adjustable calibration.
Consider for approximate audio checks with an understood microphone setup
Selectable ranges and calibration controls offer more context than a single unexplained loudness number.
Keep in mind: The developer's standards claims concern its processing and specified hardware configurations, not proof that any phone is a certified meter; do not use unverified readings for compliance or hearing-safety decisions.
