Mixers, Math and Utilities

Signal mixing, arithmetic, dynamics and nonlinear utility processing.

Mixers

Signal summing, mixing and panning modules.

ModuleDescription
MixTwo-input mix/feedback utility.
InputSwitchClick-less N-input audio signal switch — selects one of N inputs to the single output.
OutputSwitchClick-less audio signal output switch.
CrossfadeCrossfades between two audio inputs based on a modulation signal.
MixerDynamic multi-input mixer.
StereoMixerDynamic stereo mixer with pan controls.
SurroundMixerQuadraphonic mixer with gain, left/right pan and front/rear pan per input.

Math

Audio-rate math and level utilities.

ModuleDescription
AddSignal adder.
MultiplySignal multiplier.
SubtractSignal subtractor.
DivideSignal divider.
Lin2DbLinear to decibel converter.
ClampClamps an audio signal between minimum and maximum parameters.
ScaleAudio signal scaler (attenuator). Multiplies the input by a linear amplitude factor (amp). Range: -1.0 to 1.0.
InvertInverts the audio signal by negating it or mirroring it around 0.5 (1.0 - input).
ConstantOutputs a fixed constant audio-rate value. Useful as a DC offset or as a static signal source.
GainAudio gain control.

Dynamics

Envelope-driven gain and level-shaping modules.

ModuleDescription
EnvFollowConverts an audio-rate detector signal into a smoothed unipolar envelope.
AmpModMultiplies an audio signal by an audio-rate gain signal.
DuckCombined detector, envelope follower and amplitude modulator for ducking delays, reverbs and feedback paths.

Waveshapers

Nonlinear audio shaping and digital degradation modules.

ModuleDescription
ClipAudio waveshaper with hard clipping plus tanh, atan and soft-knee modes. Supports symmetric and positive-only asymmetric shaping.
Bit ReducerMono audio bit-depth reducer. Quantizes amplitude to a selectable number of full-scale levels without sample-rate reduction, dither or filtering.
Sample Rate ReducerMono sample-and-hold sample-rate reducer. Holds audio samples at a selectable update rate without bit reduction, interpolation, dither or filtering.
