  • A High-Level Programming Language for Multimedia Streaming
    Liquidsoap: a High-Level Programming Language for Multimedia Streaming David Baelde1, Romain Beauxis2, and Samuel Mimram3 1 University of Minnesota, USA 2 Department of Mathematics, Tulane University, USA 3 CEA LIST – LMeASI, France Abstract. Generating multimedia streams, such as in a netradio, is a task which is complex and difficult to adapt to every users’ needs. We introduce a novel approach in order to achieve it, based on a dedi- cated high-level functional programming language, called Liquidsoap, for generating, manipulating and broadcasting multimedia streams. Unlike traditional approaches, which are based on configuration files or static graphical interfaces, it also allows the user to build complex and highly customized systems. This language is based on a model for streams and contains operators and constructions, which make it adapted to the gen- eration of streams. The interpreter of the language also ensures many properties concerning the good execution of the stream generation. The widespread adoption of broadband internet in the last decades has changed a lot our way of producing and consuming information. Classical devices from the analog era, such as television or radio broadcasting devices have been rapidly adapted to the digital world in order to benefit from the new technologies available. While analog devices were mostly based on hardware implementations, their digital counterparts often consist in software implementations, which po- tentially offers much more flexibility and modularity in their design. However, there is still much progress to be done to unleash this potential in many ar- eas where software implementations remain pretty much as hard-wired as their digital counterparts.

  • Tiny Disco: a Cost-Effective, High-Fidelity Wireless Audio System ​ Quarter / Year Submitted: Winter 2020 ​ Student: (Print Name) ______(Sign) ______
    Tiny Disco: A Cost-Effective, High-Fidelity Wireless Audio System A Senior Project Report presented to the Faculty of California Polytechnic State University San Luis Obispo In Partial Fulfillment of the Requirements for the Degree Bachelor of Science in Computer Engineering By Luke Liberatore February 2020 Date of Submission: February 25, 2020 Senior Project Advisor: Hugh Smith Abstract 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. 2 Table of Contents Abstract 2 Table of Contents 3 Introduction 5 Stakeholders 7 Project Goals and Objectives 7 Project Deliverables 8 Project Outcomes 8 Background 9 Experimentation to help develop
