Dear all,

Further to this post I've ordered, but yet to receive, an iPod nano for field playback - to resolve the playback issue I'm trying the Logitech mm28 speaker, runs off AC & AA batteries - by all accounts and reviews it might be a bit big but it may have the grunt to provide a decent sound in the scrub.

I'd be interested in the views of anyone who has tried iPods for this purpose - I'm also interested in any audio editing software that is (a) easy to use and (b) free or cheap that will allow me to edit the announcements and also record repeats of the calls ...

Cheers and best from n-w of Alice Springs, where it is raining and cool.

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!

Hi Frank,

I have a HP IPAQ RX1950 with a 1 gig RAM chip installed.
I downloaded the shareware program DB Anywhere which allows you to
Access databases to the pocket PC and have so far set up records for all
the birds on the BA Australian list (about 830).

I have added photographs of every bird on the list, about 100 of my own,
others mainly found on the internet or in books, obviously a lot of these
are copyright so I can only use them for my own private use.

I have also added about 90 bird calls from  a CD as well as using the
to record some of my own then transferring them to the database.
Unfortunately, my hearing range is severely limited, so bird calls are not
of much use to myself, however the above does work.

The IPAQ is quite useful for birding as you can use it as a digital voice
recorder to take notes in the field, tick lists, record birds, look up
photos (as long as the light is not too bright) etc.
