Reviews and feedback

Yves Tupinier 2Interview of Mr Yves Tupinier, an eminent and respected French bat biologist and friend, who participated in the development of the SoundChaser and in situ tests.

How does the SoundChaser compare to other traditional batdetectors like the D240X, for example ?
“The main difference is that the SoundChaser combines features of traditional batdetecting tools (heterodyne /time expansion), signal visualization in real time features (oscillograms, spectrograms) with integrated recording functions (raw sound in wav format, trigger..) much more practical than what has been used till now. This makes it a professional real-time batdetecting tool that is very pleasant to use in the field.”

Al Milano (best - compressed) The renown American batdetector specialist, Alfonso Milano, just published his review of the SoundChaser on his blog.

“The SoundChaser is fairly easy to start using and enables users to record wildlife sounds with a great deal of accuracy. The application is very versatile, featuring modules which may be easily loaded/unloaded.” .

Thomas DarnisTest of the SoundChaser by Mr Thomas Darnis, a mammal specialist at the ONF (National forestry office) :

“This software is simply revolutionary in the chiropterology world.  Paired with the now famous Dodotronic 250 K microphone, it enables you to hear bats in heterodyne while viewing high quality color spectrograms, all in real time from 0 to 125 Khz. It allows you to save sequences while still recording live feed. These sequences can be analyzed right away according to the method explained in Michel Barataud‘s book “Echologie acoustique des chiroptères d’Europe”, published in 2012. The sequences can be chosen by the observer or recorded by setting the trigger’s threshold. The latter is particularly efficient because it continuously adapts to ambient noise, which avoids inappropriate recordings. 

In a nutshell, this software can do everything: from heterodyne, to direct sound and time expansion ; from viewing spectrograms and oscillograms to extensive analyzes including the frequency of energy peaks, all of which on Windows 7 or 8  or on a tablet. At the end, thanks to limiting or even avoiding hours of post-processing, it saves you an incredible amount of time identifying species and contact counting. An image for the experts? A D1000 connected to Batsound, live and in the field: the best for less than 800 €“.


North Yorkshire Bat GroupEnglish bat specialist Mrs Brigitte Donoghue, who works at the North Yorkshire Bat Group (UK), is currently testing the SoundChaser and will publish her review soon.

So far she says: “I have had a chance to use the software and it is very good.  I think it would be very useful for bat walks and other public events.”


Feedback from other users

  • “My goal is to have the least work possible and the SoundChaser meets this requirement by allowing me to save time. I have been able to detect and record remarkable species thanks to the scan (Barbastello and Rhino that I would surely have missed with an SM2). The SoundChaser is also very useful for entomology.” (Frédéric Plana, Hysope environnement, uses the SoundChaser on an Iconia W4)
  • Excellent interface that has no equivalent on the market (Jean Paul Ucrun)
  • “There are very interesting things in this tool, in particular its adaptability. You can record for how long you want when you want, you can easily load additional features, and soon we’ll be able to geolocalize recordings.”
