The Audio Anecdotes project, in the spirit of Andrew Glassner's
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
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
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.
Yes its a funny name; we like alliteration. We are also considering
Audio Applets, Sound Samples, Sound Snippets,
and others too embarrassing to mention.
Incomplete list of topic areas
Synthesis (noise, additive, subtractive),
effects (chorus, reverb, flange, time scaling),
fifo/ring buffer implementation and math,
human physiology (masking, minimum detectable change),
physics of audio (propagation speed, attenuation, doppler, sound pressure levels),
sonification, synchronization(LTC, SPMTE, resampling),
compression (lossless, lossy),
telephonics (DTMF encode/decode, voice gates, signal detectors),
audio representation (PCM, Frequency domain),
mathematics of audio (dB, power),
fast math tricks...

Thanks, I look forward to hearing from you! --
