BatSound is an efficient, high-performance tool for various types of sound analysis. It is suitable for sound analysis in general, but also includes a number of features particularly useful to analyze bat calls recorded from a bat detector.

Feature set

* An easy-to-use and powerful tool for analysis of bioacoustic sounds.
* Real-time spectrogram analysis mode with high-quality spectrogram and/or oscillogram running across the screen with simultaneous recording of the signal to the hard disk.
* Spectrogram, Power spectrum, Zero-crossing, Pulse Interval and Pulse length analyses from recorded sounds.
* Supports any Windows compatible sound card.
* Digital filtering for improving sound quality of recorded sounds.
* Printing or clipboard export of diagrams.
* Various cursorsfor marking and coordinate measurements, text annotation etc.
* Time expansion factor to give the true time and frequency scaling in signals from time expansion bat detectors.
* Multiple windows can be displayed at the same time to compare different signals or analysis results.
* Playback of sound files with time position cursor.
* The Virtual Bat Detector mode plays time expanded sound files as heard through a heterodyne bat detector.
* User defined spectrogram color mappings.
* Optional grid lnes in oscillograms and spectrograms.
* The "Pulse Characteristics Analysis" command enables automatic extraction of many important signal parameters, such as:
- Pulse duration
- Pulse start time
- Pulse end time
- Maximum frequency
- Minimum frequency
- Frequency at maximum amplitude
* The Automatic rcording mode turns the computer into a versatile "voice activated recorder", i.e. it starts recording to files as soon as the sound level exceeds the chosen threshold level.
* Comprehensive on-line help is available, reducing the need to consult the printed manual.
