I am recording nature to be played at an art show where the artists'
subject matter is a river and surounding area.

A local battery store suggested I use an "inverter" with a deep cell
battery. Anyone ever tried this and does it work well.

The alternative would be to buy a field recorder, but those seem kinda
expensive for the limited use it would see.

Thanks,

John

A good one will work well. One of the cheap "modified sine wave" ones
will be a trip to noise hell, with RFI spewing out in all directions.

So, rent one. Whoever rents film gear in your area will have a film sound
kit for rent.

Been there, done that. Scott's absolutely right. Look for
an inverter that is "Pure Sine Wave" and make sure they mean it.

It's not just RFI on the modified sine wave boxes, there is
plenty of junk in the audio baseband that is _very_ hard to
keep from feeding through even a good power supply into high
gain audio circuitry.

What about installing Audacity on a laptop (Aud is free, assuming one
has a laptop) and renting a mic for the day?

Once you have determined to what you will record, be prepared for some
real challenges. Nature is a very very quiet instrument! As a result,
you may find yourself having a hard time minimizing all of the noise
that is present. I tried this in cottage country, thinking that by
getting up at 5 in the morning I would get a lot less noise. Well
I did, but a motorboat 5 miles away is louder than the sound of the water
lapping on the shore 20 feet away. And somewhere there is always a pump
going, bringing water up to cottages.

If I ever do this again, I will try to go as far into backpacker country
as possible. And I will bring quieter mics and a recorder that doesn't
make acoustic noise.

Be sure to include an absence of power boats, as well.

I can tell you from personal experience some backpacker and canoe places
that won't work: Woodland Caribou and Boundary Waters. The common thread is
that they lease property to semi-permanent private camps within their
borders. The private camps have generators. It seems like you can hear them
for up to 20 miles.

OTOH, Quetico (the Ontario mirror of Boundary Waters) could work, because it
doesn't allow interior permanent camps, and it is big enough to get well
over 20 miles from every border. There are only about 6 jet flights that
overfly it every day and very few military training flights. The places the
float planes fly to are generally localized and infrequently flown, as long
as there are no fires.

True solitude is getting to be rare and expensive.

I've always wondered how many US recordists took advantage of the no fly
days following 9/11 to gather nature sounds. Don't think there will ever be
another similar opportunity in the United States.

I thought about it at the time, but I had too many appointments that I would
have needed to cancel.

I'm sure that a few did though.

Personally i think that "No Fly" would make a great holiday.
