Introduction

The Audio Anecdotes project, in the spirit of Andrew Glassner’s Graphics Gems, is a cookbook of audio algorithms, techniques, and implementations contributed by the community.

Books such as Graphics Gems and Numerical Recipes have inspired me and this effort. No similar book exists spanning the field of Computer Audio. I have time after time wanted to reach for such a reference. We now have a chance to help create it and help unify the audio community in the process!

Articles

The articles will be short, focused on specific issues, contain illustrations and working C code examples where possible (code will call a generic audio I/O library and will not be platform specific). Articles will provide liberal references to standard sources of information instead of attempting to provide all background information.

How You Can Help

Most importantly contact me regarding articles you would like to write! Experts are needed to help verify technical correctness. We also need people to help implement the platform independent audio library on various platforms: Windows, Mac, Linux, SGI, etc.

Audio Anecdotes?

Yes its a funny name; we like alliteration. We are also considering Audio Applets, Sound Samples, Sound Snippets, and others too embarrassing to mention.
