Awesome to hear Ivano! This is great news. Do you have any idea about
when it might be finished?
Also - do you have any sample recordings from your current Ultramic
(assuming it is going to use the same Knowles MEMS sensor)?
Thank you,
Jonas

Can you give any indication of price, Ivano? If I upgrade, I was thinking one
of your mics might be more versatile that the Echo Meter Touch. That one seems
like good value, but I don't like to be locked into using an iPhone. The
current Utramics can be used with iPhones, PCs, etc, can't they?

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.

Hi Jonas
I'm just working on it.
There's a problem with the synchronization from the usb buffer request from
the PC and the serial audio interface that receive the samples from the ADC.
In this week I'd receive the first prototype board so I can do the real
test. At the moment I'm working with the waveform generator, it's the
"worst case" for the ultramic so if it works well it'll do better in the
fileld use.
For this device I'll use the MEMS sensors from Knowles, for the WaveShark
and WaveFalcon I'll use waterproof connector so eveyone can attach their
own microphone
Regards
Ivano

Hi Peter,
You can take a look at the price in my website: www.dodotronic.com
At the moment it's not compatible with iOS but the problem can be easily
solved, I'll send a sample mic to the author of Ultrasonic app.
Echo Meter Touch is a good product but with a different application field
and different characteristics.
The main problem with Ultramic250k and Ultramic200k is the compatibility:
they are not supported by some new OS such as Win8 and WIN10
This is the reason why I'm working hard to find a solution to this problem.
All OS support the multiple of standard sampling rate such as 48, 96, 192
and obviously 384 khz.
Ultramic ADC can reach 500 khz but I still must test this frequency on
different OS, surely it's not supported by windows but probably it'll be on
Apple and Android (linux included)
Regards
Ivano

As far as I am aware, the upper limit for asynchronous USB data transfer on
Android is 384 KHz - I would be surprised it iOS was any different here.
Frankly, the biggest issue with Android is the shear diversity of devices,
and that any device needs to support USB OTG (USB Host) to power the
external mic, whether it be a Dodotronic, Pettersson, or miniMIC.
I've personally been running the Dodotronic mic on Samsung S3 and S5, on a
Moto G first gen, and on a Nexus 7 3nd gen. The Dodontronic 250 even runs
on a bargain Lenovo Tab 2, although that tablet seems to have problems with
higher sampling rates beyond that.

great news about the ultramic. I look forward at the 384k version to
override the win 8/10 problems with SeaWave. I'll release a version for
tablets with bigger buttons and controls !
I'm not an expert of Android. Which is the best application for the
UltraMic ?

I'll try and post a recording today. Depending on your intended usage, would it
be acceptable to just use noise removal? Aggressive noise removal is normally
undesirable because of the unpleasant artefacts it creates, but because we
can't know what bats really sound like, who's to say they're unpleasant in this
case?

Here's a recording made with the Discovery Kids detector:
https://soundcloud.com/petershute/bat-recorded-with-discovery-kids-ultrasonic-detector
It was recorded on a Sony PCM-M10 via a headphone jack I fitted myself to the
detector. Note that I fiddled with the volume and frequency controls on the
detector during the recording. I've noted the point where that begins with a
comment. I'm not sure how long the fiddling continued, not more than a minute
or two, I think.
No edits other than converting to mono, as it was recorded on the left track
only.
Question. Seeing as this detector was so cheap, if I buy another and use it to
record to the other track, would I have usable stereo?
