1 Notes
Development: The BATLOGGER was developed in a cooperation of the Swiss Federal Research
Institute WSL and the University of Applied Sciences orthwestern Switzerland FH W, with financial help
from the Environmental Research of the Swiss Federal Office for the Environment FOE .
Environmental conditions: The BATLOGGER is housed in a robust synthetic case for measuring
devices, ant it is operated through a polyester foil keyboard. With the many openings for GPS,
microphone, memory card, charging plug etc., it does only reach imperviousness level IP 30 and
therefore is not protected against water. When used in the field, unobserved and for extended periods of
time, the logger should be stowed in a waterproof box (Strongbox Part # 212.006) or bag, with the
microphone externally connected through a cable.
Microphone / ultrasound sensor: An active electret microphone is used as plug-in ultrasound sensor.
Attention has to be payed to a proper fitting of the microphone in its plug. The microphone itself can be
damaged by water. It must be protected from rain and extreme humidity, and it requires corresponding
positioning. For special recording purposes, the microphone can be connected with the logger through a
shielded stereo audio cable of no more than 2 m length.
Speaker A: The speaker can also be used for monitoring during recording. Depending on environment
and volume this may lead to acoustic feedback (loud whistling). In this case, reduce the volume and hold
the BATLOGGER further away from reflecting objects such as walls or your own body or use
headphones.
Li-Ion battery: The internal power is provided by a lithium-ion battery of 3,6 V and 4600 mAh. When
transporting and storing several BATLOGGERs together, the corresponding regulations have to be
followed.
Storage media SD / SDHC – card: The BATLOGGER uses SD / SDHC cards of up to 32 GB capacity
as storage media. Test have shown, that cards of different vendors may vary in writing and erasing
speed. We refrain from giving recommendations for specific products or vendors, as offered sizes and
technologies change constantly, which may also influence card performance.
Legende for display illustrations:
On the following pages the operation of the BATLOGGER is explained using symbolic representations of
the LCD display. The illustrations are only for the sake of clarity and understanding, and do not
necessarily reflect what you see on the device.

2 Overview
2.1 General
The BATLOGGER is a data logger, which records ultrasound vocalisations of bats in real-time, and stores them for
later processing on a SD / SDHC memory card.
The logger performs a real-time recording to internal RAM and subsequently stores the recordings, that fulfil certain
criteria, as sound data (sequences of echolocation calls) onto SD / SDHC card.
Apart from the bat calls, which are stored as WAVE files, additional information is written in text format into a “.xml”
file, which stores all the settings of the BATLOGGER at the time of recording, including time, date and location of
the recording (GPS data), and the temperature of the logger.
To allow a later overview over all deployments of the BATLOGGER, its operating state is being written to a “LOG”
file on the SD card.
2.2 Device variants
The BATLOGGER is offered in a slightly extended version since the end of 2012 (Model: BATLOGGER M). It
additionally includes an integrated mixer for live monitoring of the bat calls during recording. BATLOGGER M has
speaker holes on the top, 3-line display and has Part #: 212.013 on the nameplate.

2.3 Data storage
The audio files are stored on memory card as #****.wav files (where # = 4 digit serial number of the logger), with
consecutive numbering (****). For every #****.wav file, an #****.xml file is stored, which contains all parameter
settings, date, time, geographic position and temperature at the time of recording of the corresponding WAVE file.
Ultrasound data of the microphone are first written to the internal Random Access Memory (RAM) of the
BATLOGGER. After termination of a single recording sequences (Recording...), the data are stored automatically
from RAM to the SD card (Saving... #****.wav). During this storage time (duration depends on file size and card
type) ), the BATLOGGER is blocked.
2.4 Recording
The BATLOGGER can be operated in different ways. As a basic principle, when the logger is in ”Record” mode, the
signal from the microphone is constantly written to internal RAM (Sampling...).
If the logger is set for continuous recording, the RAM is filled with data and thereafter data are written to the
memory card. As the loggers RAM is limited to 32 MB, the length of a single recording sequence can not exceed
approx. 53 seconds, but can be set to less. Subsequently this recording sequence will be written as #****.wav file to
the SD card and a new recording will start, thereby overwriting data in RAM. The time required for data storage to
the memory card is largely depending on the file size but also on the type of card. In general the writing of the file
BATLOGGER Manual Elekon AG ov. 2012 4/28

should require significantly less time than the recording itself.
In manual recording the triggering has to be performed through the key pad and may also be stopped this way. If
a manual stop does not occur, the recording will stop automatically after a user selectable manual trigger time
(default = 10 sec), and the #****.wav file be written to memory card.
In automatic recording the signal from the microphone is constantly monitored and the recording started
automatically, when a triggering event is registered (detected ultrasound signal). The duration of such recordings
depends on the presence of the triggering criteria. The default setting allow for a recording duration which includes
0.5 seconds before the first and 1 second after the last trigger event (pre- and post-trigger). With the default
settings, the shortest recording duration is therefore 1.5 seconds, which corresponds to roughly 1 MB of data on
the SD card.
2.5 Check and play of recorded #****. av files
For immediate control, single stored audio files can be replayed through headphones in time expansion mode.
Ultrasound signals are slowed down by a user selectable factor x (default x = 10). A stored sequence therefore
requires an x-fold playback time of the original recording to monitor. Only recorded files can be played back and
listened to. Additionally recording details of a file such as date, time, length, peak frequency and more can be
displayed.
Single recordings on the memory card can also be erased through this mode. Erasing the complete memory card
must be achieved by formatting it (Settings menu).
2.6 Global positioning and time recording / GPS
The BATLOGGER is equipped with a GPS receiver. Its positioning and time data are stored in parallel to the
#****.wav file in a corresponding #****.xml file, and into a Google-Earth -.kml file. Further on, the travelled track can
be recorded to a GPX file.
2.7 Recording the mode of operation of the BATLOGGER
For later control of a BATLOGGER's state, its mode of operation is sequentially written to memory card into a
separate "log"-File (BATREC.log). This ”BATREC.log” file is constantly added to, and will not be overwritten.
However, formatting the SD card will also erase this log file.
BATLOGGER Manual Elekon AG ov. 2012 5/28

3 Preparation

5.3 Crest- und Period – Trigger (”Automatic” recording)
Proceed with key in the main menu to ”Start Record”.
In the setup menu, the trigger mode has to be set to
2 = Crest Adv, 3 = Crest or 4 = Period
(see page 15)
With the key to ”Recording” mode (directly or after warning of missing GPS).
If no valid GPS time is available, the BATLOGGER asks
for confirmation of the start of the recording without GPS data.
With the key , the recording mode is initiated.
The BATLOGGER is in sampling position and
awaits a trigger event (Crest or Period). In this
state, the BATLOGGER continuously digitises
signals from the microphone into internal RAM,
circularly overwriting old data (ring buffer)
(The ”5” on the display indicates present Crest factor)
Here, manual triggering is possible too: ( )
If a trigger event is detected, the BATLOGGER
displays the activity (peak frequency) and, if
Autorecord is enabled, switches to
”Recording” and stays in this mode, until
the trigger event disappears again and the
”post trigger time” has passed. The detected peak
frequency is displayed continuously.
Afterwards it switches to ”Saving”.
The recorded data, including the pre-trigger time,
are stored as * wav file and corresponding meta
information as * xml file onto SD card. Storage time
depends on the recording duration and SD card used.
During storage, the frequency that triggered the event
is displayed. This is a first hint for species recognition.
After storage, the BATLOGGER automatically returns to ”Recording”.
Automatic recording can be cancelled (back to ”Start Record”) with the keys and .
5.4 Live monitoring A
Is the BATLOGGER in record mode and live monitoring function is enabled (see page 16) the ultrasonic sounds are
output live on the speaker or headphones. Here, the bat calls are transformed into audible range after the mixer-
principle (heterodyne). The mixer is adapted automatically and continuously to the currently detected frequency of
the calling bat.
The volume can be adjusted during operation.
With the key in the record mode to “Volume”.
With the key the volume is lowered, with the key raised.

5.5 Delayed recording (Recording in time windows)
Proceed with key in If a time window is defined in the “Setup”, and at least 1 day is
the main menu to ”Start Record” activated, the BATLOGGER will start directly into ”Sleep” mode. If
preset starting time has already passed, sampling immediately starts.
With the key to ”Recording” mode (directly or after warning of missing GPS).
If no valid GPS time is available, the BATLOGGER asks
for confirmation of the start of the recording without GPS data.
With the key , the recording mode is initiated.
The dark display indicates the sleep mode and the
”wakeup time”. After wakeup normal recording
operation resumes with the pre-chosen trigger
mode until the end of the set time window.
Sleep-Mode can be cancelled with the key (confirmation: ”Aborted by User”)
Example:
•r. Days = 2
•T1 Start = 20:30 T1 Stop = 01:30
•T2 Start = 04:00 T2 Stop = 07:30
5.6 Interval recording (Recording in intervals)
As with time delayed recording time windows have to be defined and a number of days must be set. When also a
recording interval is entered, then the BATLOGGER switches to record mode at the start time, but only for a single
recording or max. for one minute.
Then further recordings are blocked for the programmed number of minutes (”RecIntvl” / default = 0 = off). This is
followed by another record mode. This interval operation continues to the end of the time window. For this interval
operation the various trigger modes can be used.
Example:
•Rec Intervall = 3

Example: 10
The recordings are played slowed down 10 times (time expansion and frequency division).
Thus the ultrasonic sounds are audible (e.g. 45 kHz -> 4.5 kHz)
The real-time playback enables the output of the original ultrasonic sounds. This can be
useful for demonstration purpose for example. Pay attention to connect a speaker with
appropriate ultrasound capability.

8 Files
8.1 The audio data file ”xxxxxxxx. av” (e.g. 10160233.wav)
After completion of recording into internal RAM, the stored data is written as standard audio WAVE file onto the
inserted SD card with the file name ”xxxxxxxx.wav”. (e.g. 10160233.wav)
The first four digits identify the serial number of the BATLOGGER and the following four digits exhibit the
consecutive number of the recorded files on the inserted SD card.
The above example therefore identifies the 233th recording on this SD card of the BATLOGGER with the serial
number 1016.
The *.wav file contains all the uncompressed raw measurement values of the analog to digital converter and a
“header”, which is specific to the wave format. This “header” contains, amongst other information, the sampling rate
of the digitiser.
Concurrent with these recorded wave data, a file containing meta information about the recording (see below) is
saved to SD card with the name *.xml (in our example 10160233.xml).
The standard *.wav files can be read and opened with general audio software or bat specific sound analysis
programs. It may be displayed as time signal or spectrogram. The latter offers best possibilities to identify species.
Elekon AG offers a specific analysis software for Windows PCs: BatExplorer. It can be found on the included SD
card or can be downloaded from www.batlogger.ch.
WSL offers BatScope, a Mac software tool for management and preview of recorded data, which will eventually be
extended to bat species identification: see http://www.wsl.ch/fe/biodiversitaet/produkte/batscope/ or [email protected]
