Hi Mike, Frank and Birding-aussers,

I am in the process of doing something similar with a MP3 player, again with
1GB capacity. In my case I am only entering a smaller reference library of
calls which I will divide into  several folders to make the calls easier to
access. Like you I have poor hearing, it is fairly normal at lower
frequencies but very limited with higher frequency calls.

I am currently experimenting with "Audacity" attempting to edit some calls
to reduce the loudness of the announcement preceeding each call while making
the actual call louder. I find I can do this but only to a limited extent
before the player starts to distort the call. Strangely the more edited
calls still sound O.K. on my computer. Perhaps I am exceeding the dynamic
range of the "el cheapo" player I bought. More work to be done!

Bruce Cox.
