That sounds interesting, but I've got a pc so I can't try it.=0D
=0D
The idea of it is to learn to recognise bird calls? I've often thought it w=
ould be handy to be able to quickly select sections of recordings of simila=
r sounding birds, and be able to play the sections one after the other in a=
 loop so you can hear the differences.=0D
=0D
Can your program do anything like that?=0D
=0D
I like the idea of being able to grab recordings from xeno canto.=0D

After last week=E2=80=99s discussion of ways to master birdsong, I decided =
to draft up a little app that would work like musical ear training, so I=E2=
=80=99ve made it available for download. It only is compiled for OSX for no=
w; I may be able to compile it for windows later.=0D

It=E2=80=99s simple to operate but here are the details of making it work.=
=0D
=0D
At the top you can turn on the bird track in the square toggle box, and add=
 in tracks of water and wind which help with the overall blend and make it =
more naturalistic (since these particular bird files are not smooth edits).=
 You can use the "open" buttons to loop your own background files (wav and =
aiff only). Levels are controlled just below so you can make your own mix.=
=0D
=0D
On the left are the 3 controls. Density is the number of birds that will ap=
pear in any given time frame, so you can start with few birds and work up t=
o a forestful. Variety allows you to let in only some of the birds, and gra=
dually increase the species diversity. However, in the current implementati=
on, it is only affecting the files as they appear in alphabetical order (to=
p of the scale is all files included, bottom is only the first file). There=
 are 28 files in the current package, representing 5 or 6 birds. They are j=
ust some placeholders to show how it might work. If people like this, I can=
 start working on ways to read from any folder you select on your disk, and=
 eventually to go to a source like xenocanto and bring web-based files into=
 the mix.=0D
=0D
The final control is distance. The birds are randomly placed into a 360-deg=
ree binaural field (put on your headphones!) and are random distances from =
your head in the center of the field. Top of the scale is entirely distant =
(you probably won=E2=80=99t hear them they are so far away!), and bottom of=
 the scale is randomly from very close to the full spectrum of distance ava=
ilable.=0D
=0D
The display on the right provides various indications of what is happening.=
 The largest spectrogram is a composite of all the birds. The bottom five s=
how the last five audio files that have played, individualized to help with=
 recognition. The filenames appear to the left as your verification of ID, =
though eventually I should be able to extract metadata and put more user-fr=
iendly data into this field. I can also make it appear on a delayed basis, =
so you can attempt your own ID before it appears,=0D
=0D
The circular indicators show the direction in the binaural field where the =
bird was placed by the spatial randomizer.=0D
=0D
Let me know if you like it and if you have any suggestions!=0D
=0D
Thanks=0D
