Blend the dry signal with a heavily compressed, makeup-gained copy — upward compression that lifts quiet detail while the dry path keeps its punch, built from FFmpeg.

Run audio through a simulated tape machine: tanh magnetic soft clipping, speed-dependent head bump and HF rolloff, wow & flutter, and tape hiss — with 3.75/7.5/15/30 IPS presets.
audio-analog-tape-saturationMedia
Add single-ended tube-preamp coloration: an asymmetric waveshaper whose bias control sets the even-harmonic warmth, with drive, tone tilt, dry/wet mix and output trim.
