WebMain indicates that high-pass filters are commonly used for directional microphones which have a proximity effect—a low-frequency boost for very close sources. This low-frequency boost commonly causes problems up to 200 or 300 Hz, but Main notes that he has seen microphones that benefit from a 500 Hz high-pass filter setting on the console. WebIt's hard to demonstrate this with audio, but very easy with images. Here's an example original image, filtered with both a near-ideal high-boost filter and a 1st-order butterworth high-boost filter: Original Image. Ideal Filter. Butterworth Filter. As you can see, the butterworth filter looks much better, despite not being ideal.
