What the experts say |
| |
"The combination of these features means that the software pretty much lives up to the claims made in the advertising flyer that it is easy and intuitive to use." ... "Avisoft provides cheap, powerful sound analysis for PC's." ... "If you already have an IBM-compatible computer of the appropriate specification, then Avisoft is a most attractive package."
Peter K. McGregor, Nottingham University and Jo Holland, University of Copenhagen: Review in Animal Behaviour, 1995, Vol 50, No 10
"I find Avisoft is a joy to use. The facility and speed with which the user can assess long recordings using the real-time display, prepare and print sonograms and other spectra quickly or export them to other Windows applications, while in full control of the analysis and display parameters, makes this an invaluable programme for bioacoustic research and education."
Richard Ranft, National Sound Archive London: Review in Bioacoustics 1995, Vol. 6, No 3
"I’ve been looking for a number of years for a software package that allows the user to simply rub out superfluous portions of the sonogram and with SASLab Pro I have finally found one."

Avisoft-RECORDER |
| |
The new dimension of PC-based Multichannel Triggering Harddisk Recording |
| |
可針對單一或多途徑的軌道錄音觸發最原始且活躍的聲音。為soundcards 和high-speed data acquisition boards提供一個寬廣的範圍，並且可適用各種版本錄放音的工具。 |
 |
| |
|
| |
Possible applications are:
- Long-term monitoring and recording of acoustic events both in the laboratory and in the field.
- High-speed harddisk-recording with sampling rates up to 1 MHz* with various data acquisition boards (Avisoft-UltraSoundGate, National Instruments, Data Translation, Measurement Computing (formerly ComputerBoards), ines) and soundcards (up to 192 kHz).
- Pre-trigger recording of sporadic animal vocalizations in the field (either manually or automated using one of the various triggering options : threshold / manual / digital input / timer / ... ).
- Individual triggering and saving of single channels from multichannel soundcards or data acquisition boards.
- Multichannel real-time spectrographic display.
- Real-time acoustic monitoring of ultrasound signals by using heterodyning, aliasing or envelope tracking techniques.
- Real-time frequency measurements, that can also be issued by voice messages.
- Recording front-end for Avisoft-SASLab Pro.
- Playback with both standard soundcards and high-speed output streaming devices.
- USV monitoring option for counting and measuring rat or mice ultrasonic vocalizations.
- Acquiring GPS location data from NMEA 0183 compatible GPS receivers and logging the geographic locations of the recorded .wav files into .gpx or .kml files.
