The M500 microphone is easily used with a tablet PC or laptop to record bat calls and other ultrasonic signals with the highest quality.
The M500 USB Ultrasound Microphone comes in a small and durable aluminium enclosure. It utilizes the same advanced electret microphone technology as the well-known D500X detector and can be used both in directional and omnidirectional modes (with or without the directional horn).
Low-noise technology, high sampling frequency and efficient anti-aliasing filter provide highest quality recordings.
The microphone comes with a free 'Lite' version of the easy-to-use BatSound Touch recording program that saves the recordings as 16 bit wav files. Real-time display of the waveform and the spectrogram as well as real-time monitoring of the bat calls are also available. The program offers various triggering modes; manual and automatic, with or without pretrigger, level triggered or frequency triggered operation.
