That is interesting Mike
There are a number of programs that you can use to filter out unwanted
noises but they certainly do not eliminate them completely and depending on
how much noise you are putting up with, this can at times make the sounds
very hollow.
You say that you are using Tape to record with? Most people on this group
have gone digital, IE: minidisk, DAT or Flashcard/hard drive recorders.
Where are the location/locations of the bird/birds? Can you move them away
from there current place? (I presume they are in some kind of cage?)
I think to do the job properly, you would have to upload your sounds to
computer, with a tape recorder you would have to go analog through a sound
card and with your given noise pollution I would not be too confident of th=
e
results this way.
There are many good filtering programs within wave editing software, I use
Adobe Audition 1.5 and I have found this to be very satisfying. Macintosh
users will use other programs with the same results. Wave comes to mind als=

Subject: [Nature Recordists] Introduction & Difficult Speech Problem
Howdy all,
You can call me Mike (not in stereo at this time); my
location is Clearwater, Florida and my name is Michael
Dalton. I joined the group at the suggestion of Raven
Simons of Performance Audio in Salt Lake City.
As a kid, I first experimented and repaired wire
recorders. During my teen years I was active in
amateur radio and obtained a commercial broadcast
license. As a result I have done limited work in
studios at commercial stations. For many years I
operated a high-fidelity sound store offering quality
products, repair, and other services.
My formal education is in physics, but I now work in a
completely unrelated area: exploring interspecies
communication. The subject of my investigations and my
writing is a Blue & Gold macaw, a large, tropical,
parrot-like talking bird.
After making what I considered to be "routine" tape
recordings of my bird's utterances, I discovered that
most people do not understand a bird's impromptu
speech. Part of the problem is that my recordings
contain automotive traffic noise from a street
adjacent to the recording location. While the noise
had little effect upon my ability to hear the words,
listeners are annoyed and distracted by the background
noise.
Are there other recordists who can decode speech
embedded in noise? Does anyone have similar
experience? Keep in mind that the bird has an
extensive vocabulary and so her words are often
difficult to grasp. She also pronounces some words
sloppily.
I would like anyone who has interest in speech and
knowledge of speech recovery from a noisy environment
to communicate with me at my e-mail address. I am
interested in digital (or other) noise reduction to
make the speech more intelligible to the average
listener too. Suggestions are welcomed.
Thanks for allowing me into your group. Any help in
wrestling with the speech recognition problems and
noise difficulties outline above will be greatly
appreciated.
Sincerely,
Michael (Mike) Dalton
Florida
