Binomial QMF

Binomial QMF stands for "Binomial Quadrature Mirror Filter". It's a type of filter that is used in digital audio applications to split an audio signal into separate "bands". It does this by using a combination of mathematical equations (called "quadrature filters") and special mirror images (called "mirror filters"). The result is a filter that can make it easier to separate different frequencies of sound within an audio signal so that they can be altered or removed.
