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. Avisoft Bioacoustics e.K.
