BIGULATOR | 一款罕见模拟母带削波器的电路模型。Biqulator 是一款模拟母带削波器的电路模型，展示了滚动增益衰减显示、传输曲线和控制面板。它

精心打造了一款鲜为人知的模拟母带削波器模型，这款削波器音量很大，但听起来却不像是在工作。其独特之处在于：一个与音频信号串联的 VCA，其控制端口由一个峰值整流器以音频速率驱动。没有包络，没有起音，也没有释放。Biqulator 正是基于该电路，根据实际设备的原理图和测量数据进行优化，并赋予了它原本无法实现的功能：多频段操作、过采样和多声道数字输出削波器。

模拟仿真：
通过电路仿真和大量测量，Biqulator 捕捉到了这款独特母带削波器的模拟核心和灵魂，除了最极端的设置外，几乎无法区分。

零启动，零释放。
整流器以音频速率驱动VCA控制端口，中间没有任何过渡。任何时刻的增益衰减都取决于该时刻的波形。Biqulator介于削波器、限幅器和饱和器之间，是一种独特的模拟电平控制方式。

对称到完全失衡
（ASYM）旋钮上的不平衡感。峰值削波器的两部分具有独立的偏置微调，因此一侧会比另一侧略早开始削波。它完全按照硬件的原理建模，然后扩展到硬件无法企及的范围。从完全对称到完全失衡。

阈
值和比率是独立的控制，但它们并非相互独立。阈值的位置会改变传递函数本身的形状，因此相同的比率在两个不同的阈值下并非同一个处理器。阈值为0时比率为100和阈值为-10时比率为100是两条不同的曲线，与模拟单元上的曲线完全相同。

单频段、双频段或三频段：
您可以将电路应用于整个混音，也可以将其拆分并为每个频段运行一个独立的实例。添加更多频段时，每个频段仍保持其特性；两个分频点可自由调节并可能重叠；每个频段的增益衰减都会显示其独特的颜色，以便您区分哪个频段正在工作。

最小相位和线性相位分频
：多频段运行时的最小相位可保持低延迟。线性相位和深度线性相位分频完全不进行相位旋转，适用于不希望出现多频段处理相位失真的混音和母带处理工作。深度分频可提供更陡峭的分离度，但会增加延迟，并且每个设置都会精确报告其延迟。

过采样至 16 倍
模拟削波不会产生混叠。数字削波会产生混叠，而且无论模型精度如何，都无法解决这个问题。如果延迟很重要，请运行 1 倍；或者将非线性度提高到 2 倍、4 倍、8 倍或 16 倍，以将混叠产物降低到硬件本身从未出现过的水平。

相位匹配并行混合
MIX 将处理后的信号与输入微调之前抽取的干信号路径混合，因此加大驱动力度不会改变干信号的电平。在多频段模式下，干信号侧具有与分频器相同的相位旋转，因此混合信号在分频器处保持无梳状失真，而不是在拐角处出现凹陷。

BIGULATOR | A Circuit Model of a Rare Analog Mastering Clipper. Bigulator, a circuit model of an analog mastering clipper, showing the scrolling gain reduction display, transfer curve and control panel

A carefully executed model of an obscure analog mastering clipper that gets loud without ever sounding like it is working. The unusual circuit is the reason: a VCA in series with your audio, its control port driven at audio rate by a peak-skimming rectifier. No envelope. No attack. No release. Bigulator is that circuit, derived from the schematic and fitted to measurements of the real unit, then given what the box never could: multiband operation, oversampling and a multi-voice digital output clipper.

Analog mastering clipper features
What Bigulator does when it is sitting on your master bus.

Exacting Analog Emulation
Through a combination of circuit emulation and numerous measurements, Bigulator captures the analog heart and soul of this unique mastering clipper, nearly indistinguishable apart from the most extreme settings.

Zero Attack, Zero Release
The rectifier drives the VCA control port at audio rate with nothing in between. Gain reduction at any instant is a function of the waveform at that instant. Somewhere between a clipper, a limiter and a saturator, Bigulator is its own flavor of analog level control.

Symmetrical To Totally Out Of Whack
ASYM is that imbalance on a knob. The two halves of the peak skimmer have separate bias trims, so one side starts skimming a fraction before the other. Modeled exactly as the hardware has it, then expanded into places the hardware cannot go. Perfectly symmetrical, to totally out of whack.

Where It Bites Changes How It Bites
Threshold and ratio are separate controls, but they are not independent. Where the threshold sits changes the shape of the transfer function itself, so the same ratio at two different thresholds is not the same processor. Ratio at 100 with the threshold at 0 and ratio at 100 with the threshold at -10 are two different curves, exactly as they are on the analog unit.

One, two or three bands
Run the circuit across the whole mix, or split and run an independent instance per band. Bands keep their identity as you add more, the two crossovers range freely and may overlap, and each band’s gain reduction draws in its own colour so you can see which one is doing the work.

Minimum and linear phase crossovers
Minimum Phase during multiband operation keeps latency low. Linear Phase and Linear Phase Deep split the bands with no phase rotation at all, for mixing and mastering work where you do not want the multiband processing phase artifacts. Deep buys steeper separation for more latency, and every setting reports its delay exactly.

Oversampling to 16x
Analog clipping does not alias. Digital clipping does, and no amount of accuracy in the model fixes it. Run 1x when latency matters or take the nonlinearity up to 2x, 4x, 8x or 16x to push the aliasing products down where the hardware never had any.

Phase-matched parallel blend
MIX blends the processed signal against a dry path tapped before the input trim, so driving harder does not change the dry level. In multiband the dry side carries the same phase rotation the crossover tree applies, so the blend stays comb-free through the crossovers instead of scooping at the corners.

Sum clipper, four voicings
A multi voice digital clipper after the analog model. Tight, Punch, Smooth and Smoother each handle the clip differently. Its ceiling draws a dashed rule across the display, and the output trim runs after it, so level and clip depth stay independent.

See it happening
Input, output and every band’s gain reduction scroll past in real time, GPU accelerated so it stays smooth on a high refresh display without eating your CPU.
