This instrument microphone from Audix samples sounds at a higher rate than other microphones.

Applications for the Audix D4 hypercardioid dynamic microphone include kick drum, timpani, toms, piano, sax and any other instrument requiring precise low frequency reproduction. The D4 utilizes an entirely new capsule specially designed to capture high SPL instruments with extended frequencies below 100 Hz. By employing sub-impulse technology that samples sounds at a rate higher than other mics, the D4 captures a truer image of the original sound than previous generation kick drum mics - this mic is flat down to 63 Hz, with a slight bump in response at 80 Hz, and a gentle roll off below 40 Hz. From 80Hz up to 1 K, the D4 is extremely linear. Frequency Range 38Hz-19 kHz response, 144 dB handling. Comes with carry pouch and mic clip.
