From the project

Miniature DPOAE infant hearing loss screening device

Android HiFi DPOAE Audio Interface ===================

This is part of the Sana AudioPulse project and may someday be officially moved over there.

The basic objective is an audio interface for an Android phone to output high-fidelity audio (two channels) to an earpiece and to record back audio from a microphone in the earpiece. As the features-of-interest in the response are below 0dB SPL, this requires very high precision.
