Lang,
Yes I'd be interested to hear your wave file of insects.
I record insect sounds at 48kHz on DAT, then I input these (in real time)
via analogue connection to my iMac at 44.1, and then process that file in
Peak. Some of my insect sounds are 12-13 kHz. These sound as good as the
original, I think.
I presume you are transferring your sounds digitally to your computer? The=
n
changing the sample rate in Peak?
This may not be at all relevant to your situation Lang, but some time back =
I
had difficulties in properly converting some sound files to half speed, in
Peak LE VST. The converted sound was very strange, tinny and echoey. Then
I found a solution. To make a half-speed file I selected keys "Command I"
then halved the sample rate from 44.1 to 22.05 (and doubled the length of
the file), to give me the half-speed file. But the sound was tinny. So I
then went to DSP/"Convert Sample Rate" and converted the file back to 44.1.
The file still played at half-speed but the sound quality was restored!
Maybe this is just an iMac thing, but thought it might be of interest.

Subject: Re: "noise maps" of cities in Europe?
Speaking of NOISE. This morning, as I was getting in my car to go to work, =
I
glanced up in the sky and was astounded at the number of jet trails. I
counted exactly 10 trails. These are all high-flying jets that have nothing
to do with my hometown of Ithaca. It is so incredibly annoying. It was only
8 am, and already the sky was full of noisy silver birds.
Lang
Yes. There are several. Most notably in R. Murray Schafer's
publications on noise that refer to the European and UN standards
generally addressed and often followed in the more civilized nations
of Europe.
