Hi,

 



 I was wondering if the group has experience with remote sound recorders 
analogous to camera traps that you can leave for about one month. I would want 
to record nocturnal owls, bats, hyrax, bushbabies here in East Africa.  Either 
one that can be triggered by sound or programmed to record a sound window of  
say 2 hours per day to limit battery time. Does anyone have any recommendations?

 



 

 Regards Andrew

Hi Andrew,

Ultrasonic versions of what you describe are used extensively for bat
research and monitoring and there are ones designed for use in the audible
frequency range as well. The Wildlife Acoustics Song Meter range should be
suitable for the kind of work you want to do:
http://www.wildlifeacoustics.com/

They're pretty expensive though - hopefully someone else on the group may
know of a cheaper option!

All the best,

Tom

Yes. Bracket and copy the bat sequence. Then go to the drop-down menu File, 
select New, and paste the sequence. With the sequence still bracketed, go to 
drop-down menu Effects, select Time and Pitch, then choose Stretch and Pitch 
(process). Uncheck the box Lock Stretch and Pitch Shift. Set Pitch Shift to -20 
(semitones) and you should have bats within comfortable hearing range. Good 
luck.

Hi, I think the best option to "hear" the structure of bat calls is to use
the function "adjust sample rate" to lower the playback sample rate. This
reduces the frequency range of the recording and expand the time
accordingly, thus allowing to perceive the thin structures of calls. If you
need to maintain the same duration the best option is to perform an FFT
shift of the frequencies, but it seems Audition is unable to do this.
Apparently it should be possible to catch a frequency region (by a
rectangular expanding box or by using the lazo) and copy it elsewhere, e.g.
at a lower frequency position, but it does not work. Someone has a solution
?

Lowering the frequency while maintaining the time scale is a really great 
feature of Audition as I described earlier. We do that all the time (�cause, 
unfortunately, I�ve lost the top octave of my hearing range, now). No kidding, 
it�s pretty amazing. If you need help, I am happy to personally walk you 
through the process on Skype. Takes about 2 minutes, total.

Hi Bernie,
    yes, your method works pretty well, however my preference is for a time
expansion to better perceive time details.

As for the direct downshift of high frequency sounds, in our recording
software it is possible to record ultrasounds and to hear them downshifted
by fft in real-time. With the cpu power now available even on tablets, the
software performs in real time the methods described more than 15 ago for
file analysis.

I agree, Gianni. I was just confirming the possibilities with commonly 
available software. It should be noted that one can also time-shift the 
signals, as well, with Audition. Just leave the LOCK STRETCH AND PITCH SHIFT 
box checked. As you say, it�s not possible in real time, though. However, Lang 
Elliott, because of hearing problems, has designed and built a system that will 
accomplish what you describe, though. It�s called the SongFinder and can be 
looked at, here:  http://hearbirdsagain.com If things keep regressing for me as 
they have, hearing-wise, I�ll be needing one of those soon enough.

If something like a Songfinder is an acceptable solution, there are far cheaper 
bat detectors available. I bought a "Discovery Kids Ultrasonic Detector" on 
eBay for about $40. It's a heterodyne detector, and is of course a toy compared 
to some, but it seems to work ok. I suspect though, that a software solution 
would be better.

Thank you Bernie and Gianni
Gianni suggestion would be so simple but your are right, it doesn't work 
in auditions, in my versions any way.
Bernie, you got me in the right direction. I suspect our versions were 
different as the last step wasn't there. After a bit of playing around, 
I got the results I was looking for.
The exercise was, early one morning I recorded some bats which were 
coming close. The echo was recorded which of course, I couldn't hear 
plus their wings/ feeding noises. The aim was to bring the echo part 
down to hearing range and blend with wing/ feeding noises. The result 
wasn't perfect but at least I'm on the right track.
Cheers
David

I forgot to add that you first need to see the bat vox in spectrogram mode in 
order to bracket it.

BK

********************************************

Yes. Bracket and copy the bat sequence. Then go to the drop-down menu File, 
select New, and paste the sequence. With the sequence still bracketed, go to 
drop-down menu Effects, select Time and Pitch, then choose Stretch and Pitch 
(process). Uncheck the box Lock Stretch and Pitch Shift. Set Pitch Shift to -20 
(semitones) and you should have bats within comfortable hearing range. Good 
luck.

I'd say they're more of an intense bone-marrow sound ;) For
me maybe the most impressive exposures on remote Fiji
islands were the bats during sunset: hundreds that would
dive/swoop/respond to your mimicked squeeks while on their
way home!


On an island, a place of edges, the ocean provides a counter-narrative, 
nonlinear in
what it reveals; "time's arrow" is modified by the rhythmic cycle of the sea as 
it
encounters, and ever transforms, the shore. Historical, archaeological, or even
narrative knowledge is challenged by its meeting with the sea that offers up 
its own
kind of knowing. We need to stretch, even confound, our usual frames to take 
account
of such knowledge.

Global Islands Project -- ongoing series of multi-media 
pdf-ebooks/field-recordings -- a
pastoral, pictorial and phonic elicitation of island parameters. An intensive
examination of small islands and their paradigmatic solutions to globalism...
Ethnographically a shared world of historical experience -- not the 
romanticized and
divided universe of them and us.

Your feudal-world is based on mutual relief at your common corruption. Maybe 
some
cultures are based on even worse. But that wouldn't change the bad faith of it 
and as
years go by, you wake at night in terror of your whole life being an act of 
shattered
faith, where everything is self-interest and nothing more, where every human
interaction is driven by a silent, even subconscious calculation of some 
ulterior
motive, to the point that a sea of bad faith has taken over your whole life, 
there's no
small island left from which you can even try to build a bridge of good faith, 
because
even that effort becomes suspect, even good faith is nothing but 
self-interested, even
altruism is nothing but solipsistic, even your professed agonizing right here 
right now
is nothing but a gesture, made to the conscience in order to assure it that it 
exists.

Deglobalisation is not a synonym for withdrawing from the world economy. It 
means a
process of restructuring the world economic and political system so that the 
latter
builds the capacity of local and national economies instead of degrading it.
Deglobalisation means the transformation of a global economy from one integrated
around the needs of transnational corporations to one integrated around the 
needs of
peoples, nations, and communities. We cannot talk about construction without
deconstruction, reintegration without disintegration.

The world (universe) is mostly filled with the black hole (or the vast and deep 
sea )
of the forgotten. Compared with this, the world of memory is only a small 
island in
the vast "sea of oblivion."

A traveller, who has lost their way, should not ask, 'Where am I?' What s/he
really wants to know is, 'Where are the other places?'

Vientos del pueblo me arrastran

You cannot politically defy the institutions when all you really wanted
was to be clasped to their bosoms and hope in time to be cherished under
the very framework of oppressive values you are thinking of overcoming.
That would be co-optation, revolution only in the sense of a circulation
of elites rather than the extirpation of the very impulses of elitism.
