It was designed for the special needs of bioacoustics, but it can moreover be used for any other audio signals. Possible applications are: Long-term monitoring and recording of sensory events both in the laboratory and in the field. High-speed harddisk-recording with sampling rates up to 1 MHz* with various data vanquishment boards (Avisoft-UltraSoundGate, National Instruments and soundcards or audio interfaces (up to 192 kHz). Pre-trigger recording of sporadic unprepossessing vocalizations in the field (either manually or streamlined using one of the various triggering options : threshold / transmission / digital input / timer / time program ... ). Individual triggering and saving of single channels from multichannel soundcards or data vanquishment boards. Multichannel real-time spectrographic exhibit (frequency [kHz] vs. time [s]). Multichannel real-time spectrum exhibit (amplitude [dBFS] vs. frequency [kHz]) with temporal averaging and temporary peak hold. High-pass filtering for attenuating low-frequency noise. Real-time sensory monitoring of ultrasound signals by using heterodyning, aliasing or envelope tracking techniques. Playback through both standard audio interfaces and National Instruments DAQ devices, optionally with playlist functionality. USV monitoring option for counting and measuring rat or mice ultrasonic vocalizations. Batch mode for processing large numbers of animals in USV drug testing procedures. Acquiring GPS location data from NMEA 0183 or Windows Location API uniform GPS receivers and logging the geographic locations of the recorded .wav files into metadata chunks and into separate .gpx, .kml or .shp files (automatic geotagging). The defended BatUndeniabilityTrigger Filter tool can distinguish bat echolocation calls from other unwanted signals, such as insect noise. An streamlined undeniability parameter measurememt tool can quantify various undeniability parameters and classify the calls based on these parameters in real-time. The created log files provide a quick overview on the recorded data, which can moreover be hands transferred via low-bandwidth internet connections (these log files are much smaller than the original .wav files). Customizable metadata input tool for embedding user-defined database records directly into the recorded .wav files. These embedded data records can succeeding be accessed from SASLab Pro and subsequently integrated into a metadata base. Real-time weather data logging (into dXML and bext .wav file metadata chunks) from Kestrel 4xxx Pocket Weather Tracker, Davis Instruments Vantage Pro2 / Vue / Envoy and Airmar LB150, PB150, PB200 series devices and many other worldwide PC weather stations through a generic real-time log file interface option HID TEMPer, Weather Station Data Logger, Cumulus, Weather Display, Heavy Weather, KlimaLogg Pro). * The maximum sampling rate for real-time exhibit and streaming to disk depends on the type of vanquishment workbench and computer performance (USB, PCMCIA or PCI board, processor speed, graphics adapter, disk transfer rate, ...) Data spritz scheme Avisoft-RECORDER screen shot configuration diolog box Up to 8 channels, each sampling at up to 1 MHz can be monitored simultaneously. Optionally, Avisoft-RECORDER can record from up to 32 audio channels. Each waterworks can be triggered separately by variegated trigger events. An trigger event can be the exceeding of a unrepealable energy threshold within a pre-defined frequency interval. This mechanism prevents triggering caused by undesired disturbance signals outside the frequency range of the unprepossessing vocalizations. Additionally, an entropy parameter can be used to discriminate between noise and pure-tone signals. For increasingly sophisticated signal filtering, the Avisoft-SASLab nomenclature facility may be used. Alternatively, trigger events can be keystrokes, joystick sawed-off hits or timer intervals. Once a trigger event has occurred, the prescribed channel(s) will be written into numbered WAV-files onto the nonflexible momentum as long as the trigger event is active. In order to capture sounds preceding the trigger event, a pre-trigger elapsing can be specified. Additionally, a hold-time can be specified to prevent wearing up of related sound elements. The created event files are time-stamped (at sample clock resolution) enabling subsequent re-assembling into larger continuous files for precise temporal analysis. Sound-activated recording can be restricted to user-defined periods of time (and optionally putting the computer to sleep in order to save power).The well-timed Avisoft-SASLab Pro sound wringer software and the LOG file output support quick navigation through the captured sound files. For single-channel applications a special low-cost version is available. Both standard audio interfaces and National Instruments DAQ devices can be used for playing when .wav files. Playing a .wav file can be initiated simply by dragging the desired file into the RECORDER using window. There is moreover a versatile playlist full-length enabling streamlined playback of long file sequences. playlist screen shot The USV monitoring option provides instant results on the uninventive ultrasonic vocalizations. Various descriptive statistics items such as the total number, total duration, midpoint elapsing or standard deviation of the detected USVs can be reported. USV monitoring screen shots GPS data logging screen shots System Requirements Operating system: Microsoft Windows 10, 8.1, 8, 7 or Vista including Intel-based Apple Macintosh running Parallels or Boot Camp Analog input: Soundcard or audio interface with worldwide MME/WDM driver, UltraSoundGate, National Instruments E, M or X-series DAQ device with 16-bit resolution (conventional NI-DAQ or NI-DAQmx driver)*, Data Translation* or Measurement Computing* data acquision devices For GPS data logging, a GPS receiver complying with the NMEA-0183 data protocol or the Windows Location API is required (either a Bluetooth GPS receiver, a USB GPS mouse, a handheld GPS unit or just a computer with integrated GPS/GNSS capabilities) * Please note that the operation of these data vanquishment boards is not unchangingly straightforward. Decent knowledge and wits is required to connect the analog inputs (and outputs) properly. In contrast, worldwide soundcards and the Avisoft-UltraSoundGate devices are much easier to handle.
