Our project is to create a device that receives a wideband audio input and applies spectral warping to shift the input’s partials in real time, based on user-controlled parameters. The device can be used to detect and identify sources of ultrasound in the environment, such as bats in nature or transceivers in an urban setting. The device will include an ultrasonic microphone, an LED display to represent the spectrum and parameters, potentiometer and encoder knobs to control the parameters, a microprocessor to apply the device’s effects to the input, and an aux port to function as an output. Our primary accomplishment is that, to our knowledge, our project is one of the first devices designed to sonify ultrasound in real time. A couple notable challenges we faced involved unfamiliarity with components required to build the project and a lack of a designated mentor. Some areas to explore for future improvement is the revision of the enclosure to allow for proper mounting, filters and microphone replacements to improve input audio quality, and buffer read/write synchronization to prevent race conditions.
