Bioacoustics
Last Updated: 980324
The subject of bioacoustics covers the range of study of sounds emitted
by living things, and also sounds which affect the lives of living things.
The latter is not taken too broadly, so don't expect to publish
scholarly papers on the effects of playing "Nirvana" CD's to house sparrows.

Tutorial on sampling (under construction)
Digital sampling of acoustic signals has provided a basis for a whole class
of analyses. But diving right into the technical literature can cause massive
confusion. I'm going to try to make some of the concepts clearer.
First up is the concept of time-varying signals. An acoustic signal
is one characterized by alternating compression and rarefaction of the
medium. Over time, a transducer that is sensitive to changes in pressure
will produce changes in either resistance or voltage that can be amplified
and recorded.
Next is the concept of periodicity. [...]
