It is worth noting that the cut-off frequency is not the point at which attenuation begins. You use a pass filter’s cut-off frequency as a reference for the point at which frequencies to one side are filtered and to the other side are allowed to pass. Let’s look at each of these controls in further detail… Cut-off Frequency: They are the filter’s cut-off frequency and the filter’s slope. Simultaneously, it filters out the frequencies that are higher than that point. Simultaneously, it filters out the frequencies that are lower than that point.Ī ‘low-pass filter’, also referred to as a ‘high-cut filter’, allows only frequencies that are lower than a certain point to pass through. It allows only frequencies that are higher than a certain point to pass through. High-pass filter:Ī ‘high-pass filter’, also referred to as a ‘low-cut filter’, does exactly what the name suggests.
In this article, I’ll explain what pass filters do, how you can use them, and the benefits of doing so. Those are high-pass filters (HPF) and low-pass filters (LPF). There are two main types of pass filters that are used in music mixing. parametric EQs and shelving filters), a pass filter allows you to filter out portions of the frequency spectrum. That’s because, unlike other EQs which turn frequencies up or down (e.g. A pass filter is a really useful tool in audio mixing.
