for Gram32, or for Audacity - both of which are available as freeware.
 Of course I have to add the caveat that using any sophisticated piece of
 equipment without some understanding of how it works and what the
 limitations and potential problems (e.g. artefacts or misleading
 displays) is dangerous.  Even using the old electro-mechanical Kay
 Missilyzer required some background knowledge of acoustics and signal
 analysis in order to interpret the resultant sonagrams correctly.

 Subject: Simple spectrogram programs?
  From time to time we receive inquiries at the Bioacoustics Research 
 Program from people looking for an extremely simple, easy-to-use program
 for making spectrograms of animal sounds. These queries are usually from
 people who do not have much experience or specialized training in 
 bioacoustics, and who may not be sophisticated computer users. They 
 typically do not need a lot of flexibility, bells and whistles,
 capabilities, etc. The programs used by most researchers would be more 
 complex than necessary and potentially confusing or intimidating.
 is the key.
 Does anyone on the list know of particular programs that fit this 
 description, preferably with recommendations?
 Thanks in advance for any assistance.
