Have you ever wondered how digital hearing aids are developed? Most people have probably never given this complex problem a second thought.

The Linux kernel (with the PREEMPT_RT patchset), GNU tools and Debian are the key ingredients for a project by the Cluster of Excellence group Hearing4all to research the development of new hearing aid algorithms.

The open Master Hearing Aid (openMHA) is an open-souce cross-platform toolbox which allows a user to form hearing aid processing chains. The software is scriptable to allow researchers to update and test algorithms on-the-fly.

At this session we'll present openMHA running on Mahalia, a mobile research platform composed of a BeagleBone Black Wireless, custom 6-channel soundcard (Cape4all) and battery. You'll learn how 64 Studio tuned the system to process all 6 channels of audio through complicated algorithms in less than 4ms!
