(Above, the microphone that I named TETA, an original DIY stereo microphone.)
Various types of microphones can be used to record sounds in nature, from a simple dynamic monophonic microphone (very few actually used in recent decades), to complex stereophonic systems, very often Do It Yourself, to adapt them to the specific needs of personal taste, or depending on of the environment in which one operates. Moreover, there are particular microphones that allow to record the frequencies in the ultrasonic band, these are the so-called ultrasonic microphones, actually quite rare in their placement on the market.
