A filter is an audio effect that removes selected frequency ranges from a track. DJs often use filters to simplify transitions or gradually introduce musical elements.
Filters are usually referred to by their type and the frequency band they impact (e.g. high pass, or low cut).
Common types include:
- Pass - Emphasizes a specific frequency range
- Cut - Cuts a specific frequency range
- Notch - Allows only a specific frequency
Common bands include:
- High / Hi - highest frequencies (high percussion)
- Middle / Mid - middle frequencies (vocals, instruments)
- Low / Lo - lowest frequencies (bass, kick)
