Microphone sensitivity varies bydevice by roughly ±15 dB, so the absolute values are not calibrated — they areuseful as relative comparisons, not as measurements you could cite.If you ship this, add a per-device calibration flow and label readings accordingly.That is a real piece of work and the price reflects that it is missing.No in-app purchases.
