Tiny Disco: A Cost-Effective, High-Fidelity Wireless Audio System, Luke Martin Liberatore

Computer Engineering

The Tiny Disco is a WiFi based concert system, featuring improvements on popular “Silent Disco” concerts. Rather than being tied to compression and bandwidth restrictions present in traditional silent disco systems, the Tiny Disco system can deliver 320kbps+ audio quality, and allows listeners to bring their own headphones, further lending to the high quality audio experience.

Tiny Disco uses a Raspberry Pi as the audio server, and Espressif ESP32 microcontrollers as audio receivers/clients. The Tiny Disco is primarily geared toward smaller concerts and niche events where audio quality is valued, though due to its WiFi-based architecture, it can be expanded …

Wireless Ad Hoc Networks For Mobile Devices Via High Frequency Sound Waves, Yashar Bahman

Computer Engineering

The purpose of this research it to give mobile phones the ability to create a cross-platfor wireless ad-hoc network. To accomplish this the phone’s speaker/microphone will be treated as a modulator/demodulator (or modem for short). The idea is that the phone will generate sine waves at various frequencies to output them on the speaker on one end and also record audio with the microphone to analyze and decode it into data on the other.

Once complete, these functionalities will all be rolled up into one easy to use library named Wave, which can be used to send data back and …

Bluebeats, Jake Muir, Aaron Martinez, Mishal Shah, Richard Wissemann

Computer Engineering

Our group’s senior project is called BlueBeats. The BlueBeats product was created in order to provide a wireless audio gateway between Bluetooth enabled devices. Users of BlueBeats can use an Android or computer application to interface with the BlueBeats device. The Android and computer applications allow the user to easily scan for devices, add/remove devices from their personal list, and pair/connect with a selected Bluetooth enabled device. Once the user is connected to the BlueBeats device, he/she has two options. The first option occurs when the user connects the BlueBeats device to a device with speakers (using 3.5mm audio jack …
