Simple Yet Powerful DSP
Behind the single knob lies a carefully engineered signal chain that delivers professional-grade saturation without aliasing or artifacts.
Parameter Smoothing
20ms ramp smoothing on the drive parameter prevents zipper noise during automation and knob movements.
4x Oversampling
Signal upsampled 4x using FIR equiripple filters before nonlinear processing, pushing aliasing harmonics well above Nyquist.
tanh Waveshaping
Core saturation: tanh(drive × x) / tanh(drive). Normalized sigmoid that generates natural even and odd harmonics — warm, tube-like character.
DC Blocking
1st-order highpass at 20 Hz removes DC offset introduced by asymmetric saturation. Clean output, no rumble.
Makeup Gain
Automatic gain compensation keeps perceived loudness consistent regardless of drive amount. No manual level matching needed.
Stereo Metering
Real-time LED-style input/output level meters with thread-safe atomic reads for accurate visual feedback.
Under the Hood
Built with JUCE 8 and C++17. Every DSP algorithm crafted for authenticity and performance.
tanh Waveshaping
Smooth S-curve saturation that naturally models tube amplifier behavior. No harsh digital artifacts — just warm, musical harmonics.
4x Oversampling
FIR equiripple anti-aliasing filters at 4x sample rate. Nonlinear processing without aliasing artifacts even at high drive settings.
DC Blocking
1st-order HPF at 20 Hz removes DC offset from asymmetric waveshaping. Clean signal path, no subsonic buildup.
Makeup Gain
Automatic gain compensation ensures consistent output level regardless of drive amount. No manual level matching required.
Stereo Metering
Thread-safe atomic level metering for both input and output. Real-time visual feedback with smooth ballistics.
Plugin Delay Compensation
Reports oversampling latency to the DAW for proper PDC. Perfect phase alignment in complex signal chains.
