A filter is a manipulation tool which can alter the relative balance of rates within a sound.
What is a filter?
A filter changes the frequency of making a sound by making parts of it. Filters allow you to focus on these parts of the world, or to take away parts that you do not like, such noise or ‘hiss’. As we learn in Pitch and Soundscape Music , sounds are often made up of many different frequency parts.
