Frequencies under 20hz get harder and harder to hear and capture with a microphone the lower the frequency goes. In this video I record frequencies all the way down to 10hz all recorded from a Skar SDR 15" Subwoofer. I could go even lower and record single digit infrasonic frequencies. Watch the video to find out how I did it. Please leave a like and subscribe for more audio related content and more.
