There are five main types of filter: low-pass, high-pass, band-pass, band-stop and notch. This might because there is a perceived problem with the signal, to enhance it, or to help it blend in with other signals better.Īnd the tools we use to do this are filters and equalizers. Often it is desirable to boost some frequencies and perhaps cut others in level. Note the difference in capitalisation between the full name of the unit and its abbreviation. 'hertz' (Hz) means 'vibrations per second'. Low frequencies represent low notes, high frequencies represent high notes and overtones. An audio signal consists of a range of frequencies from low (20 Hz) to high (20,000 Hz). But how are they different, and how should they be applied? Both EQ and filters alter the frequency response characteristics of a signal.
