Sound Analysis - Avisoft Bioacoustics

Sound Analysis
The sound files created by Avisoft-RECORDER can be easily
analyzed in the Avisoft-SASLab Pro sound analysis
software. Time-expanded bat calls can also be acquired
through a standard sound card using the integrated real-time
recording spectrograph. This software allows rapid analysis
and supports a wide range of analysis (and synthesis)
options. It is probably the most powerful software tool that is
currently available for bioacoustic research. Many features
are specifically designed for bat sound analysis (zerocrossing analysis, instantaneous frequency and compressing
of long call sequences).
Various cursors support quick measurements. A powerful
automatic parameter measurement option can further
accelerate investigations. Among the parameters that can be
measured automatically are call duration, dominant
frequency, start and end frequencies. The software can also
be configured for subsequent automated call classification.
Additionally, various statistics can be derived from these
parameters.
Spectrograms and waveforms can be printed at high quality.
For printing long call sequences at high resolution, the
printout can be spread over several rows and pages.
Avisoft-SASLab Pro is the best choice for researchers
interested in advanced sound analysis and synthesis.
What are the advantages of the
UltraSoundGate system over
other bat detectors?
The 16 bit A/D conversion with integrated adaptive AAF filter
and the newly designed high-quality microphones enable highquality recordings with superior signal-to-noise ratios and low
distortion.
The integrated peak level meter (consisting of 5 LED's) helps
adjusting the recording level appropriately (for preventing both
overload and too soft recordings).
Unlimited continuous recording time (the only limitation is the
size of the computer harddisk).
Real-time spectrogram display with optional automated call
parameter measurements and classification.
A TTL-compatible digital input allows to synchronize the sound
recordings with other signals (e.g. video).
Due to the sturdy construction of all its components, the
UltraSoundGate system will work reliably even under rough
field conditions.
The accomanying RECORDER USGH software can
simultaneously acquire weather and GPS data from third-party
devices. The collected coordinates, which are saved into
common .gpx or .kml log files, can be imported easily into GIS
applications such as Google Earth.
A versatile XML-based metadata input tool providing userdefined database fields with optional validation capabilities
allows to enter the documentation already in the field. This
metadata information is stored directly into the .wav files (into a
custom dXML RIFF chunk), which means that it is tighly
connected to the original recordings.

The UltraSoundGate system has been developed by
Avisoft Bioacoustics having more than 24 years of experience in
designing animal sound analysis software, digital signal processing
systems and ultrasound recording / detecting equipment.
The accompanying Avisoft-RECORDER USGH software
saves the incoming sounds onto the PC harddrive and
provides a real-time spectrogram display, numerous
triggering options including sound-activated and timer
controlled modes. A GPS data acquisition option supports
the geographic documentation of field surveys.
Recording ultrasound has never been easier!
