There are six types of parametric audio filters:
•
High Pass Filter
•
Low Pass Filter
•
Bass Shelf
•
Treble Shelf
•
EQ
•
Notch
The filters may be used alone or in combination to adjust for room
acoustics, furnishings, and speaker deficiencies to achieve the desired
flatness.
High Pass
A high-pass filter passes on a majority of the high frequencies to the
next circuit and blocks or attenuates the lower frequencies. Sometimes
it is called a low-frequency discriminator or low-frequency attenuator.
A high-pass filter circuit passes all signals that have a frequency higher
than the specified frequency, while attenuating all frequencies lower
than its specified frequency.
