My curated list of audio DSP (digital signal processing) and plugin development resources. New resources may be added in the future. Feel free to open a PR if you wish!
Code Libraries - A list of useful libraries for audio software.
DSP Cookbooks - A list of algorithms and equations you can use and reference for your own DSP designs.
DSP Playgrounds - Software tools that are useful for quickly and easily prototyping DSP.
Sound Design & Music Production - While this is not strictly development related, knowing how plugins are actually used to make and edit sound can give valuable insight.
System Tools - A list of system tools useful in developing audio plugins and software.
Technical Reading - A list of useful articles, blogs, and scientific papers on algorithms and techniques for audio DSP.
