These tools are for fellow bat detector designers and other ultrasonic hardware hackers. With these it is possible to test ultrasonic capabilities of sound cards. Once you know you have a sound card capable of recording and/or playing ultra sound these tools can then be used for tesing other hardware.

If you have a soundcard capable of recording ultra sound this applicaton can emulate a heterodyne bat detector. With it you can convert ultra sonic sounds in the range 15kHz to 95kHz (with a 192k sound card) into audible tones.

With the addition of some inexpensive home built hardware it is possible to use a PC running this software into a high speed ultrasonic recorder.
