Many of you know that I use a "Birder's hearing aid" called a  Songfinder 
because I have no high frequency hearing. I Couldn't hear a warbler  if he 
sat on my cap.  The Songfinder picks up only high frequency sounds  and 
reduces the frequency (pitch) by half, into a more normal hearing range  where I 
can hear them. 
I recently had a brainstorm (I know, that's dangerous) and  figured out how 
I could plug my sound recorder into the Songfinder so I can  record the 
bird songs more or less as I hear them. Below is a track featuring a  Canada 
Warbler and his friends, (2nd Canada, Waterthrushes, BT Green, etc.)  the way 
it sounds to me. You might be surprised what I hear, especially if your  
hearing is suspect. For whatever reason it's not exactly the same as when live, 
 but close enough. The speed of the playback is not changed, only the 
frequency  (pitch) of the high sounds).
I've also included a track of the same bird recorded  "normally", so you 
can see the difference.  And a bonus normal track - of a  Boston Hollow BT 
Blue singing his faux Cerulean song. If you want to listen,  click "download", 
then "play" for each track.
