Distortion

@maru/distortion-bitcrusher

Sample-rate and bit-depth reducer: anti-imaging one-pole, held-sample phase accumulator, quantization steps, boost and dry/wet with boost compensation.

@maru/distortion-chebyshev

Chebyshev first-kind polynomial waveshaper over the shared fixed-4x oversampled interpolation and FIR decimation stage.

@maru/distortion-classic-amp

Classic nonlinear amp v1 pre-cabinet voice: input high-pass, pre-emphasis, 4x oversampled preamp and power waveshapers around a three-band tone stack…

@maru/distortion-color-shaper

Wet hard clipping, asymmetric saturation and rectification with tone/DC filtering.

@maru/distortion-decimator

Wet-only DaisySP Decimator port: raw sample-and-hold cadence and defined fixed-point bit clearing without filtering or added latency.

@maru/distortion-direct-overdrive

Direct zero-latency DaisySP overdrive with bounded drive-dependent gain and soft clipping.

@maru/distortion-drive

Canonical fixed-4x rational-drive transfer, FIR state, tick and reset semantics.

@maru/distortion-jitter-reducer

Deterministic sample-and-hold reducer with sampling-clock jitter.

@maru/distortion-octave-divider

Thresholded zero-crossing octave divider with envelope, tone and DC filtering.

@maru/distortion-oversampled-waveshaper

Canonical fixed-4x oversampled waveshaper transfer, FIR state, tick and reset semantics shared by kernel nonlinear units.

@maru/distortion-rational-soft-clip

DaisySP/stmlib rational SoftLimit x(27 + x^2)/(27 + 9x^2) and its +/-3-bounded SoftClip in the source's f32 operation order, as the CHOMPI firmware uses them.

@maru/distortion-sample-rate-reducer

DaisySP SampleRateReducer (MIT, from Mutable Instruments Plaits): a phase accumulator re-samples the input at a 0..1 ratio of the host rate, places each held value at…

@maru/distortion-taper

Tape processor: nine-control cook, companding encode/decode, flutter fractional delay, bias slew, mid/sub split, head-bump resonators and stereo soft clip.

@maru/distortion-tone-shape

Tone-15.1 rational distortion transfer with an f32-rounded result, silence gate and a bounded drive amount.

@maru/distortion-triode-stage

Bounded static triode load-line solver and prepared tone/DC filtering.

@maru/distortion-voiced-overdrive

Wet voiced drive composing canonical transfer, input low-cut, tone filtering and output trim.

@maru/distortion-voiced-wavefolder

Wet wavefolder composed from the canonical Daisy fold, post-fold RBJ DC blocker, ToneFilter and output trim.

@maru/distortion-wavefolder

DaisySP periodic triangular wavefold with signed pre-gain and offset.
