# DSP Stages List

This a list of all the supported stages that can be used with the DSP pipeline tool:

- Biquad Stages: can be used for basic audio filters.

  > - Biquad

  > - BiquadSlew

- Cascaded Biquads Stages: consist of several biquad filters connected together in series.

  > - CascadedBiquads

  > - CascadedBiquads16

  > - ParametricEq8b

  > - ParametricEq16b

  > - NthOrderFilter

- Compressor Stages: allow for control of the dynamic range of the signal, such as reducing the level of loud sounds.

  > - CompressorRMS

- Compressor Sidechain Stages: use the envelope of one input to control the level of a different input.

  > - CompressorSidechain

  > - CompressorSidechainStereo

- Envelope Detector Stages: measure how the average or peak amplitude of a signal varies over time.

  > - EnvelopeDetectorPeak

  > - EnvelopeDetectorRMS

- FIR Stages: allow the use of arbitrary filters with a finite number of taps.

  > - FirDirect

- Graphic EQ Stages: allow frequency response adjustments at fixed center frequencies.

  > - GraphicEq10b

- Limiter Stages: allow the amplitude of the signal to be restricted based on its envelope.

  > - LimiterRMS

  > - LimiterPeak

  > - HardLimiterPeak

  > - Clipper

- Noise Gate Stages: remove quiet signals from the audio output.

  > - NoiseGate

- Noise Suppressor Expander Stages: control the behaviour of quiet signals, typically by tring to reduce the audibility of noise in the signal.

  > - NoiseSuppressorExpander

- Reverb Stages: emulate the natural reverberance of rooms.

  > - ReverbRoom

  > - ReverbRoomStereo

  > - ReverbPlateStereo

- Signal Chain Stages: allow for the control of signal flow through the pipeline. This includes stages for combining and splitting signals, basic gain components, and delays.

  > - Bypass

  > - Fork

  > - Mixer

  > - Adder

  > - Subtractor

  > - FixedGain

  > - VolumeControl

  > - Switch

  > - SwitchSlew

  > - SwitchStereo

  > - Delay

  > - Crossfader

  > - CrossfaderStereo

  > - Router4to1
