Easy to install, BatScan will record and play back sound samples through your windows compatible sound card. However, a sound card is not necessary in order to analyze and display audio spectrograms.
BatScan processes PCM format digital audio data such as .wav sound files. Default settings have been optimized for use with Batbox Duet.
