“本书探讨了数字信号处理、其在声音中的应用，以及其声音效果如何运用于音乐中。第一版是在年度 International Conference on Digital Audio Effects 协助下编写的，本书在科研和产业界对该领域的推进都起到了关键作用。Digital Audio Effects 各个领域的飞速发展催生了新算法，新版将这些新内容与基本概念的更佳阐述以及相关技术的讨论相结合。内容将涵盖滤波器、延迟、调……”

……应用。很多语音活动检测（VAD）就是这么工作的；无非就是针对你的输入去调调系数和阈值。另外关于包络跟随（envelope following）很有用的参考资料有 DAFX 的教材 [2]、Will Pirkle 讲 C++ 音频的教科书 [3] 以及 Zölzer 的著作 [4] [1] https://github.com/m-hilgendorf/rusty-compressor [2] https://www.amazon.com/DAFX-Digital-Effects-Udo-Z%C3%B6lzer/... [3]……
…application. A lot of Voice Activity Detection (VAD) works this way; it's just a matter of tuning the coefficients and thresholds for your input. Also useful reference for envelope following are the DAFX text [2], Will Pirkle's textbook on audio in C++ [3] and Zölzer's text [4] [1] https://github.com/m-hilgendorf/rusty-compressor [2] https://www.amazon.com/DAFX-Digital-Effects-Udo-Z%C3%B6lzer/...

……https://news.ycombinator.com/item?id=20491766 —— 最后补充一句！另一位合成器开发者（在 Modwiggler 上）也亲自推荐了上面评论里提到的同一本 DSP 书，所以估计挺值得一读的！Udo Zolzer 的《DAFX》
…https://news.ycombinator.com/item?id=20491766 —— Last note! Another synth maker personally recommended the same DSP book as noted in the comment above (on Modwiggler), so it’s probably worth checking out! Udo Zolzer's "DAFX"
……大家在这里提到的其他资源你基本上选哪个都行。我个人最喜欢的是 Steven Smith 的 DSP 书、Julius Smith 的资源（附带可运行的 MATLAB 脚本），以及 Udo Zolzer 的 DAFX 专著。
…you could go with pretty much any of the other resources the others have mentioned here. My personal faves are the Steven Smith DSP book, Julius Smith's resources (with its runnable MATLAB scripts), and DAFX book by Udo Zolzer.
Zölzer 的《DAFX》涵盖了音频 DSP 的所有基础构建模块。这本书与一年一度的国际音频 DSP 大会同名。
DAFX by Zölzer covers all the fundamental audio DSP building blocks. The book is eponymous with the annual international audio DSP conference.
……很好的参考资料。缺点是示例是用 matlab 写的，但正文和 matlab 代码讲得足够清楚，完全可以写出你自己的实现。另外 [2] 也是一本介绍整体 dsp 概念的很不错的书。[1] 《DAFX - Digital Audio Effects（第二版）》编者：Udo Zölzer https://dafx.de/DAFX_Book_Page_2nd_edition/index.html [2] 《Understanding Digital Signal Processing》，Richard Lyons
…good reference. A con is the examples are in matlab, but it's clear enough between the text and matlab code to write your own implementation. Also [2] is a decent book for overall dsp concepts.
