This is the most up to date version of Batsound.

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.

Features include;

* An easy-to-use and powerful tool for analysis of bioacoustic sounds.
* Support for Windows XP, Windows Vista and Windows 7.
* New recording and playback routines. Separate "Recording Status" dialog box showing the status and enabling pause/resume recording. Pause function also added for playback.
* Functions to facilitate using files generated with the D1000X detector:
* Support for larger files
* "Play Speed" function to allow playing files with high sampling rate at reduced speed (i.e. as a time expanded file)
* Display of "File Properties", including any GPS data that was stored in the file.
* New file formats for improved compatibility with other sound editor programs.
* Import function to enable opening other file types than wav (e.g. mp3). This requires a codec for the desired format (which most computers already have).
* "Open Next" function opens the next file relative to the current active file (in alphabetical order).
* More than one file can be opened in the Open File dialog box.
* Support for higher sampling frequency (recording up to 192 kHz, playback up to 768 kHz) and bit depth (up to 32 bits). This requires that the sound card supports the chosen sampling frequency/bit depth.
* Commands to move the cursor to the beginning/end of file.
* Min and max frequency can be chosen in "Spectrogram Settings - default" dialog box.
* Various minor changes and bug fixes.

BatSound is optimised for analysis of time expanded bat calls (i.e. those made by a Time Expansion detector such as the Pettersson D-240X). It can be used with a Frequency Division detector (such as the Pettersson D-230), but the resolution in the diagrams will be lower. This is a consequence of the fact that each bat call from a Frequency Division detector is shorter than that of a Time Expansion detector. Manually decreasing the FFT (Fast Fourier Transform) size in Batsound for the spectrograms is sometimes required with Frequecy Division signals in order to improve the appearance of the diagrams.
