AudioBench: Speaker Mic Test

AudioBench walks you through quick listening checks for your phone's or tablet's speakers and microphone, so you can tell whether audio is working before a call, a trip, or a repair.

• Play a rising tone sweep at a low default level, with a level slider you can adjust while it plays
• Test the left and right channels one at a time
• Play a short 1000 Hz reference tone through the current output
• Watch a live microphone meter with current and peak levels
• Record how each check sounded, such as heard, uneven, or no sound, and add a note
• Save the latest report and share it as text

Microphone readings are digital levels in dBFS, not calibrated sound-level measurements.
