I am new to acoustic application and want to use the audiomoth to collect the dolphin's sound. i am confused about the mems microphone's frequency( SPM0408LE5H-TB
Frequency Range:100Hz to 10 kHz) and the AM's sample rate(192kHz). If AM's sample rate is far beyond the microphone's frequency , is the data valid?
Hi, Thanks for the message. Yes, the Knowles data sheets usually give the MEMS microphones audible frequency response range (this is the flattest part of the frequency range); although the frequency response is less flat out of this range, the microphone is actually capable of picking up frequencies well into the ultrasonics.
