WARM / plugin 02
harmonic saturation done right.
add analog warmth and character to anything. tape, tube, transformer. three saturation circuits that actually sound different. precise harmonic control, not random distortion.

features
what makes WARM different.
three real characters
tape is warm and gritty. tube adds rich even harmonics. transformer goes deep with asymmetric character. they actually sound different.
precise harmonic control
each harmonic is controlled independently. not random distortion. precise harmonic architecture.
spectral-aware drive
per-band spectral pre-gain shapes the signal before saturation. the spectral display shows exactly what's happening.
program-dependent response
an envelope follower modulates drive with input level. louder signals push harder, like real analog circuits.
under the hood
the signal path.
spectral pre-gain
STFT analysis with 40 ERB bands shapes the signal before saturation. each frequency region gets independent drive control via the spectral display.
per-character soft clipping
tape uses symmetric tanh. tube uses a bias-shifted sigmoid that naturally generates even harmonics. transformer adds a quadratic asymmetry term for deep even-harmonic richness.
Chebyshev polynomial waveshaping
7th-order Chebyshev polynomials give independent control of each harmonic. the fundamental is always protected. only harmonics 2-7 scale with drive.
antiderivative anti-aliasing
2nd-order ADAA with 2x oversampling for ~52 dB alias rejection. bypassed at high sample rates. alias-free saturation without wasting CPU.
K-weighted auto-compensation
loudness-matched output using ITU-R BS.1770 weighting. the saturated signal never sounds louder than the dry. you hear the character, not the volume.
