![]() RESUMO: O Raspberry Pi (Rpi) é um microcomputador completo integrado em uma única placa (single board computer, SBC). Finally, this article didactically describes the necessary steps for configuring devices using mediators such as PulseAudio and obtaining the PortAudio library for use in Python. ![]() What's new in the operating system (OS) as well as microcomputer architecture regarding settings for audio devices are accordingly addressed. In this second part of the tutorial, more advanced ways of configuring signal input devices are explored, in addition to pointing out the functional differences and limitations between models 3 B+ and 4. This paper seeks to assist the scientific community by providing usage instructions and tips. Thus, the versatile Raspberry Pi offers numerous modes of configuration and operation. There are currently a number of different Rpi models, for example, the Raspberry Pi 3 B + and Raspberry Pi 4 B, the latter launched in mid-2019. Its main advantages are its cost-benefit, ease of use, and integration with several other devices. As such, it can be used both didactically and in professional automation tasks. Raspberry Pi (Rpi) is a complete microcomputer integrated onto a single board (SBC). Finally, some of the ongoing research projects of the students are described. As a fundamental part of the engineer's formation, the infrastructure used, whether state-of-the-art or cost-effective equipment, is detailed in the context of teaching and research. ![]() The placement of graduates in fields and their workplaces are presented as outcomes. The interaction of the university, the acoustical engineer, and society is also presented and clarified. The program employs several active learning strategies, like project-based learning, aiming to transform abstract into concrete knowledge. In the following, the program of study and subjects are elucidated and detailed, and the teaching methodologies used are also discussed. This article presents its complete academic program, its creation process, and the professional establishment of the acoustical engineer. In Brazil, acoustics was taught in graduate programs, until the creation of Acoustical Engineering in 2009, at the Federal University of Santa Maria, an integral undergraduate program dedicated to acoustics, audio, and vibration (lasting ten semesters). It is taught, in general, as part of engineering, physics, or architecture programs, or even in graduate programs specialized in the theme. Furthermore, the design of new open-source plugins strengthens the free software community as a consequence.Īcoustics is a broad field of knowledge that extends branches all over the physics of wave phenomena, psychology, natural sciences, and engineering. The main goal of this project is to create an instrument that is cheaper than most commercial synthesizers but still provides professional quality sound. In this paper, some notion of how to make a plugin using an open-source language named Faust (Functional Audio Streaming) is presented as well. Zynthian allows for the addition of new plugins and other contributions by being an open development platform. Measurements of the synthesizers tested are presented, characterizing some of their capabilities, as well as how parameter changes influence signal frequencies and time responses. Depending on the MIDI controller’s size, that is, the trigger of the sound system, the device can also be a very portable instrument. It demonstrates how to make a workable instrument that can be fed by a power bank and combined with a rechargeable loudspeaker to allow for live music performance anywhere. ![]() This paper presents the assembly of a low-cost synthesizer on a Raspberry Pi 3B+ (Single Board Computer, SBC) using the open-source software Zynthian.
