Abstract/Summary

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 to events of a few hundred people fairly easily.

The Tiny Disco system was developed and tested, and performed successfully using a test setup. Only one client was tested due to cost constraints, but load testing was performed against the Raspberry Pi server, as well as bandwidth/audio quality analysis.
