My own preference for reasonably simple spectrogram programs would be 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.

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, measurement capabilities, etc. The programs used by most researchers would be more complex than necessary and potentially confusing or intimidating. "Simple" 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. ___________________________________________________________________ Russ Charif [EMAIL PROTECTED] Bioacoustics Research Program http://birds.cornell.edu/BRP/ Cornell Lab of Ornithology PHONE: 607-254-2408 159 Sapsucker Woods Rd.
