Thanks Peter,
I looking forward to your recordings.
I currently use Magenta Bat-5, which is a heterodyne as well and it is
unfortunately quite noisy.
So that is why I am researching the more “higher-end” options out
there…
Regards,
Jonas

to give you an answer it is important to know if you just need to hear if
there are bats around, in such a case a very cheap heterodyne bat detector
is enough, or if you want to make high quality recordings.
To make good recordings it is much better to use a digital bat detector
with high sampling rate direct recording to a memory card. Some also have
"traditional" options to listen to the ultrasounds being recorded by
heterodyne or by zero-crossing based frequency division. To stay cheap, if
you can use a laptop for recording, I could suggest an ultrasonic
microphone with usb interface. A good affordable option is the dodotronic
ultramic. On the net you can find interesting projects based on the
ultramic and raspberry PI to build a low cost ultrasonic recorder.

Thanks Gianni for the tips.
Yes - the sound quality is very important to me. So I wonder how does
freq. division / heterodyne / time stretching sounds on better bat
detectors, or whether is the laptop + high sample rate recording the
only option for me.
I have a good recorder for regular recording (Sound Devices 702) and it
can record in 192kHz sampling rate, so maybe a device which would output
both demodulated and original signal would be great for me (so I could
possibly record/monitor both at the same time).
Also - would be interesting to see AES-compatible high frequency digital
mics.. maybe a future upgrade idea for Dodotronic? :)

Jonas

if you want to stay compact with a hand-held device I'd suggest a bat
detector with direct continuous digital recording to SD card. The so called
"time expansion" it is just a trick of some old digital bat detectors that
record an ultrasonic call and immediately after they reproduce it at slower
rate. Modern digital bat detectors continuously record to a memory the full
spectrum of the signals and at the same time do some type of frequency
conversion to provide audible feedback (zero crossing, frequency division,
heterodyne, time expansion). Digital recording at high sample rate with a
digital bat detector or an ultrasonic USB mic connected to a computer is
the only valid solution to get high quality recordings.
Unfortunately the SD 722 (or at least mine) at 192 kHz has a not optimal
frequency response. See http://www.unipv.it/cibra/res_techtest_uk.html
Dodotronics, Petterson, Wildlife Acoustics offer ultrasonic microphones
with interface to PC/Mac/Tablet. If you know other makers, please let me/us
know.

In that case common electret microphones (which can be found in most
inexpensive bat detectors) should be avoided. Better results (lower noise floor
and flatter frequency response) can be obtained with true condenser
microphones. This one for instance can be attached directly to field recorders
such as the Sound Devices 702:

Dear Raimund,
do you have any sample recordings made with this setup?
It doesn’t need to be bats - I am going for all kinds of ultrasonic
sounds (including insects).
And I guess there is no way to have a demodulator with this setup for
monitoring purposes?
Regards,
Jonas

Hi Jonas,
Here are a few recordings that were made with the CM16/CMPA microphone
connected to an UltraSoundGate USB microphone at an original sample rate of 250
kHz (taken from http://www.avisoft.com/sounds.htm). The phantom-powered version
of the microphone (CM16/CMPA-P48) would produce similar recordings.

Yes that is true. You would only have the level meter on the recorder as a
signal indicator. It might therefore be useful to use a cheap heterodyne bat
detector in parallel.

Raimund

Thank you very much Raimund.
I have to say the noise seems to be still quite an issue. I am probably
too spoiled by the regular frequency range and what is currently
possible with low-noise microphones. Anyway - thank you very much for
your time and responses! Your products are definitely on my shopping
list for the future.

I am new to this group so I hope it's ok to mention this, but I've developed an
Android app that - in conjunction with an ultrasonic mic such as any of the
Dodotronic mics or Pettersson Elecktronik's new M500-384, will record full
frequency spectrum signals (within the limits of the nyquist frequency of each
mic, of course). In the case of the M500-384 with a sampling rate of 284 kHz,
that's an upper frequency of 192 kHz.
The app shows a real-time spectrogram and wave amplitude display, supports
rea-ltime monitoring in the audible range via frequency division or heterodyne
tuning (either manual or automatic), and in addition, supports time expansion
in playback mode. Of course, the app also supports recording through the TRRS
jack, but those recordings are not ultrasonic.
The app will also automatically geotag recordings, and you can set a trigger
to automatically record if a signal is within a specified frequency range and
intensity. It also supports a timer, and I am just about to upload a new
version that supports remote notification via SMS messaging and email when an
automatic trigger is fired.
It runs on smart phones (e.g. Moto G 1st gen, Samsung S3, Samsung S5) and
tablets that support USB Host mode. I currently charge $5.99 through the Google
Play Store - for that price, you can install it on as many of your Android
devices as you'd like as long as the account is the same as the Google Play
account.
Believe me, this isn't really a profit making endeavor - but as it former
biologist and now software developer, I developed it for my own use recording
bats here in the Pacific Northwest, and the income helps defray some of the
cost of new testing equipment, and several mic manufacturers like Lars at
Pettersson and Ivano at Dodontronic have been incredibly supportive. And while
I am constantly adding features, the intent has never been to supplant existing
desktop analysis systems, but rather complement them by providing a convenient,
cost-effective way to record ultrasonic sounds.
Anyways, I mention it because if you already have an ultrasonic USB mic, the
app provides an easy way to record with your smart phone. In fact, I just
received a miniMIC and I will be working to support that in the next few days.
More info about the app is at my website Digital Biology
http://www.digitalbiology.com - it's called 'Bat Recorder'.

Hi all
I'm actually working on a new Ultramic with 384khz sampling rate and with
integrated micro sd card so in order to record you only need this device
and an external power supply. I'm trying to make it waterproof so it can be
left outdoor. Since the firmware can be upgraded remotedly all the feedback
and requests from users can be taken into account for future improvements.
Last but not least I'm tring to keep it cheap so everyone can use it
