How Do I Test the Microphone on My Smartphone, Tablet or Other Portable Device?

Testing microphones embedded in devices such as tablets, phones and other mobile devices can be challenging as they typically don't have the internal signal routing to return the test signal back to SoundCheck. In cases like these, an "open loop" measurement process can be employed.

A SoundCheck example sequence, Open Loop Microphone Sequence demonstrates how to measure such a device by recording a signal on the device under test, transferring that recording to the computer running SoundCheck and then using a Recall step to import the recorded time waveform into SoundCheck for analysis.
