System Integration

Avisoft-UltraSoundGate is fully integrated into the sound recording and analysis applications Avisoft-RECORDER and Avisoft-SASLab Pro.
Avisoft-RECORDER provides the following key-features in conjunction with UltraSoundGate:
  • Multichannel real-time spectrogram display (0% - 87.5% overlap), waveform envelope display, energy waveform within selected frequency range,
  • Pre-tigger harddisk-recording with widely selectable trigger options. Trigger event threshold definition for sound-activated recording can be done graphically by mouse,
  • There will be no limitations on the duration of continuous recordings (harddisk space rather than RAM size limits the duration of single recording sessions),
  • ASCII-format LOG file containing date, time and duration of each recorded event and optional text comments,
  • Manual triggering by the UltraSoundGate button,
  • External triggering through the UltraSoundGate digital input (TTL-compatible, 2.5mm mini jack). This external signal can also be used to enable/disable the sound-activated recording mode.
  • Multichannel recording with UltraSoundGate 416Hb/416H/816H/1216H with either separate triggering of each channel (separate .wav files for each channel) or simultaneous triggering for all active channels (one single multichannel .wav file containing all channels). The latter configuration is suited for passive acoustic location of animals because all channels are packed into a single data stream, which secures the phase relationship between all channels.
  • Automated call parameter measurememt tool
  • Real-time acoustic monitoring through the soundcard (heterodyning or aliasing technique).
  • High-pass filtering for rejecting low frequency noise.
  • The Bat Call Trigger Filter can efficiently prevent triggering unwanded noise.
  • Acquiring GPS location data from NMEA 0183 compatible GPS receivers and logging the geographic locations of the recorded .wav files drectly into .gpx, .kml or .shp files.
  • Real-time weather data logging from external temperature sensors / weather station devices.
  • Time program for putting the computer to sleep in order to save power and limit the recordings to predefined time intervals (optionally relative to sunrise or sunset).
  • LANC/SMPTE time code signal tracks (fed into the DI inputs) can be used to synchronize the recorded .wav files with video or to synchronize several (distibuted) UltraSoundGate units.
