Common filter types used in audio synthesis include:
* Low-pass (high-cut) filter: - removes higher frequencies
* High-pass (low-cut) filter: - removes lower frequencies
* Band-pass filter: - removes frequencies outside a given band
* Notch filter: - removes frequencies within a given band
* Shelf filters: - raise or lower frequencies above or below a cut off point.
* Peak filters: Raise- raise frequencies within a given band
* Formant filters: - raise multiple peaks, often in such a way that they mimic the human voice.
* State variable filters - e.g. include simultaneous low-pass, high-pass and band pass outputs as well as voltage controllable cut off frequency and resonance (Q)
 
There are many ways to implement most filters, and each has its own specific audio characteristics or flavour. Some common features across most filter types include:
