Nearly all programs allow you to stretch or compress the time scale,
allowing you to back off for a general look, or zoom in to a particular
portion of a song for finescale analysis.

What a wealth of expert information is generated by Naturerecordists. (Eve=

if a lot of it is beyond my ability to understand it.)
Compiled, it would make a wonderfully useful book, but I guess the same
problem as with the electronics comes up: there are simply too few nature
sound recordists to interest a publisher. (Unless perhaps if there is some
way we naturerecordists could turn publisher.)
A lot of attention is being given in recent postings to the frequency scale
of sonagrams. What about the relation between the time scale and the
frequency scale?
Imagine a note which is a glissando slide up in pitch. Shorten the time
scale relative to the frequency and it approaches a vertical stroke on a
sonagram. Lengthen it enough and the trace approaches horizontal.
Anyone like to comment on the approaches adopted by various sonagram-type
programs?
