Abstract
The Open-Source software movement has demonstrated the value and quality of open-source tools and includes well-established systems such the Android Operating System. This movement is expanding to hardware and when designed properly, open-source hardware combines the user-friendliness and dependability of commercial products with the high performance and flexibility of scientific tools developed by researchers in their own laboratories. In this research, we present a hardware and software platform entirely open-source, designed to spur innovation in sound and speech processing algorithms. The first prototype includes a Teensy 3.6 board which leverages the Arduino development environment while providing powerful computational capabilities. This processor board is paired with custom-designed electronics for audio control, power management and wireless communication. The software base is designed for multiple users: (1) “experts” who optimize new algorithms directly in firmware; and (2) researchers who interact with existing algorithms to modify parameters and evaluate their performance in different conditions. Hearing aid research and other audio signal processing fields will greatly benefit from the open sharing of algorithms on one common platform that is easily obtained from existing vendors. Here we present the current functionality of the platform, as well as how to access it and contribute to this exciting Open Source project.
