Filter Banks

Filter banks are systems that split an audio or signal into multiple parts, each containing specific frequency ranges. Think of them as a set of sieves that separate a mixture into different layers based on pitch, allowing more detailed analysis or processing of each layer. This is useful in applications like audio equalization, noise reduction, and signal compression, enabling targeted modifications or analysis of different frequency components within a complex signal. In short, filter banks efficiently decompose a signal into manageable, meaningful pieces for better processing or understanding.
