What is another word for high-pass filter?
Pronunciation: [hˈa͡ɪpˈas fˈɪltə] (IPA) 
A high-pass filter is an electronic circuit that allows signals with high frequencies to pass through while blocking those with lower frequencies. It is commonly used in audio processing to remove low-frequency noise or to selectively amplify high-frequency signals. However, there are different names for this type of filter depending on its application. Some synonyms for high-pass filter include low-cut filter, treble filter, high-frequency filter, and bass-cut filter. Each term implies a specific purpose and range of frequencies for the filter, but they all ultimately serve to eliminate unwanted signals and enhance the quality of the audio output.
