Why does Peak never reset?
Peak is a session high-water mark tied to Start/stop resets when you restart the microphone.
Overview
Mic Tester derives level from RMS of the sampled waveform and amplifies moderately for readability—use it before calls to sanity-check polarity, phantom power, Bluetooth latency, or whether the OS routed to the headset mic instead of a USB podcast interface.
