SPEAKER AND MICROPHONE TEST
The speaker and microphone tests allow the user to test the audio playback and capture the capabilities of the device being tested. The speaker test will play a music recording and prompt the user for a pass/fail decision based on the audio quality.
The microphone test will listen for the user’s voice and display in a bar the level at which it could pick up the voice. The user is then prompted to make a pass/fail decision based on the performance seen with the microphone's ability to pick up sound.
