One thing I have wanted to try is using a digital sampling
keyboard (like Herbie Hancock uses) to sample bird calls and
then play them back. I know you get interesting results
just playing a tape recording of the bird. But it would
be great to be able to choose a portion of a call or a specific
call for a specific situation. Check out the STOKES Bird
behavior books for some listings of calls and behaviors. As
for actual call waveforms I have no idea where to look.

I have an Amiga computer with a sound digitizer and software that lets you graph the sound waves and play around with them, cut and paste, slow down, speed up, mix, etc. I used it on my budgie. I recorded a few of his chirps. When I played them back he went nuts. Started singing and flitting around his cage. After a while I noticed that he would answer the recorded call with the same call. If I played chirp 'A' he answered with a chirp 'A'. I talked to him for about 45 minutes. After a while though he quit answering. I think he got wise that it wasn't a real bird he was talking to. > > And what is the structure of complicated bird song.

His chirp graphed out to look about as complicated as you would see looking at a similar graph of a human voice. Many harmonics. Looks like an EEG scribble. It would be very difficult to synthesize such a sound from scrap. > > Any help on this matter would be appreciated. > > Thanks, Your welcome. -- John Sparks | {rutgers|uunet}!ukma!corpane!sparks | D.I.S.K. 24hrs 1200bps ||||||||||||||| sparks@corpane.UUCP | 502/968-5401 thru -5406 As far as we know, our computer has never had an undetected error.
