Coursera 课程：声学、模拟和数字信号详解 课程概览： 本课程旨在帮助学习者理解声学、模拟和数字信号之间的区别，以及模拟到数字（ADC）和数字到模拟（DAC）转换过程。课程将深入探讨以下核心概念： * **信号基础：** 学习声学信号是什么，以及它如何被转换为可录制的模拟信号。 * **模拟信号：** 什么是模拟信号，以及其基本特性。 * **数字信号转换：** * **采样：** 理解采样过程，即如何从模拟信号中提取数据点。 * **量化：** 探讨量化过程，即将连续的模拟值映射到离散的数字值。 * **比特深度和抖动 (Dithering)：** 了解比特深度对音频质量的影响，以及抖动的作用。 * **量化噪声：** 识别和理解量化过程中产生的噪声。 * **模数转换 (ADC)：** 详细解释模拟信号如何被转换为数字信号。 * **数模转换 (DAC)：** 讲解数字信号如何被转换回模拟信号以供播放。 * **音频接口设置：** 学习如何正确配置音频接口，包括优化延迟和缓冲器大小（Buffer Size），以获得最佳录制效果。 课程特色： * **适合所有人群：** 无论是否有技术背景，只要对音乐充满热情和好奇心，都可以学习。 * **从零开始：** 课程内容循序渐进，没有先决条件。 * **理论与实践结合：** 讲解数字音频处理的基本理论，并提供实际的音频接口和软件设置指导。 * **应用广泛：** 适用于音乐制作人、DJ、音乐家以及使用数字音频工作站（DAW）如 Cubase, Logic, Pro Tools, Fruity Loops，或 dj 软件如 Traktor, Serato, Virtual DJ 的用户。 * **互动保障：** 讲师承诺在24小时内解答所有学员问题，保证100%的问答率。 * **无忧学习：** 提供 Udemy 的终身免费访问权限和30天退款保证。 本课程是讲师音乐和 DJ 课程系列的第一部分，旨在让学员能够有意识地管理数字设备中的音频信号，无论设备品牌或软件如何。即使是智能手机的音频处理也基于本课程介绍的理论。
Hello and Welcome toAcoustic, Analog, and Digital Signals ExplainedSo...What is an analog signal? How does the analog-to-digital conversion process work? What about digital fundamentals? And what is the digital-to-analog audio converter? And the quantization? With this course, you will be able to answer all these questions and more! At the end of this course, you will be able to understand: the differences between acoustic, analog, and digital signals;what is an analog signal;the sampling process;the quantization process;bit depth and dithering;the quantization noise;the analog to digital conversion;the digital-to-analog converter;driver and buffer setup. Some practical course applications include:Correctly Setting your Audio InterfaceOptimize LatencyOptimize the Buffer SizeGet the best from Your Recordings.To achieve this goal, the course will start from the very beginning: we will talk about what an acoustic signal is and how it can be properly transformed, recorded, and played back in a digital system through the analog-to-digital audio converter. I will also give you some quizzes to do to confirm what you have learned during the various sections of the course. And, if you want to go into more depth on some particular topics, a couple of external resources are also included in the course lectures. Starting as it does from scratch, this course is intended for everybody. No requirements are needed except your musical passion and curiosity. It aims to introduce all the basic theories to understand the sampling process, the playback or mixdown of digital audio material through your digital audio card. If you are a producer, a DJ, or a musician, or if you use a so-called DAW (Digital Audio Workstation) like Cubase, Logic, Pro Tools, Fruity Loops, or a DJ software like Traktor, Serato, or Virtual DJ, this course will explain how and why some setting could or should be applied to your audio card or software configuration. However, if you are already an audio engineer, this course is not for you. It is the very first module of all the music and DJing courses I teach so it starts from the very beginning and you don't need to know anything about the topic to start. Basically, it introduces conscious management of audio signals through digital devices regardless of the brand or software used. Even your smartphone is based on the theory explained here. Generally speaking, it's a good thing to know how an audio card works if an audio card is used during the management of digital audio content. Whether you are an audio newbie or an enthusiast or want a conscious knowledge of your audio card, this course is for you. 100% Answer Rate! Every single question posted to this class is answered within 24 hours by the instructor.Also, remember Udemy's lifetime free access to the course and full 30-day Money-Back Guarantee. I'll see you Aboard!
