Orra Ducker——逐频侧链闪避
大多数人使用侧链压缩来实现闪避，但这会降低整个信号的音量。Orra Ducker 只对实际发生冲突的频率进行闪避，它可以从任何音轨在任何 DAW 中触发。而且，配合 Orra Link，侧链路由直接集成在插件中，因此从不同音源向多个实例发送信号，在任何 DAW 中都能实现相同的简单工作流程。

频谱级、逐频段闪避，覆盖约 1000 个频段，而非宽带
绘制焦点频带，将闪避目标对准低频、刺耳的中频或全频段
分辨率控制：可实现精准的窄频闪避或宽广柔和的闪避
通过 Orra Link 在每个音轨上叠加多个实例，支持 36 个侧链通道，可从任何 DAW 中的任何音轨进行键控
四种延迟模式：HQ、平衡、快速，以及用于监听的零延迟宽带实时模式
一个大型分析器同时显示输入、侧链、输出和实时闪避曲线
每个实例均可选择自键控、宿主侧链总线或任何 Link 通道
柔和的焦点频带、立体声检测器链接以及每个控制项的完全自动化

闪避重叠部分，而非整个信号
逐频段闪避，而非逐推子闪避

Orra Ducker 对两个信号运行 FFT，并仅在两个信号实际重叠的频率处进行闪避，因此底鼓可以在贝斯声中腾出空间，而不会降低整个贝斯声线。

常规路由
在某些 DAW 中，虽然可以实现在同一音轨上运行多个闪避器，每个闪避器都使用不同的信号源，但这非常繁琐，而且每个 DAW 的设置都不一样。你需要辅助音轨、总线切换、发送路由，每次切换都要跟宿主软件重新“搏斗”。

Orra 的方式
Orra Link 让你摆脱路由的烦恼。信号源选择直接在插件内完成，每个实例只需从下拉菜单中选择触发信号，最多可将 37 个侧链信号源连接到同一音轨。无需辅助音轨，无需总线切换，无论使用哪个 DAW，工作流程都完全相同。

Orra Link 是一个小巧的发送器插件，与 Orra Ducker 一起发布。它将音轨的音频广播到共享总线上的一个编号通道，项目中所有 Orra 旗舰插件都可以读取该通道。

将其拖放到任何音轨或总线上，选择一个通道（链接 1 到链接 36），该音源即可作为项目中任何 Orra Ducker 实例的触发器，即使在通常不允许跨总线进行侧链的宿主程序中也可以使用。

工作原理
逐频段而非逐推子
普通的闪避器会测量侧链信号中的一个数值（即整体电平），然后拉低一个推子。Orra Ducker 会对触发信号和你的音频信号都进行 2048 点 FFT 变换，将它们分别分割成大约一千个频段。每个频段都有自己的检测器和增益计算器。

仅对重叠的频段进行处理
只有当侧链中对应的频段超过阈值时，信号中的某个频段才会被闪避。这就是为什么底鼓可以在贝斯声部中占据空间而不会降低整个贝斯声部的原因——只有它们共享的频段才会受到影响。

分辨率是精细的雕刻工具
分辨率决定了每个频段的衰减程度，可以是精准的窄频，也可以是宽广的平滑。它区分了精确的凹陷和柔和的倾斜。

现场模式的特殊性
现场模式会跳过 FFT 变换，运行经典的宽带包络闪避器，使用一个检测器和一个增益，实现零延迟的现场监听。其他所有模式都是全频谱模式。

信号流
触发源（无/外部/链接）→ 每个频段的检测器 → 每个频段的增益计算（阈值、比率）→ 时间平滑（起音、释放）→ 频率平滑（分辨率）→ 聚焦掩码（低切/高切）→ 应用于您的音频。立体声检测在增益计算之前由链接控制进行混合。

分析器
四条曲线
输入（绿色填充）、侧链触发（金色线条）、输出（蓝色填充）和实时闪避曲线（红色）。输入和输出之间的间隙表示衰减量，并已显示出来。

聚焦控制柄
两个金色控制柄用于设置闪避范围的低频和高频边缘。您可以直接拖动它们，也可以使用低切和高切旋钮。频段外的区域会变暗，表示该区域未进行闪避。拖动控制柄会写入自动化数据。

衰减刻度
红色闪避曲线在其右侧边缘的独立标尺上读数，与 dBFS 刻度无关。右键点击“DUCK”可放大显示：6、9、12 或 24 dB（默认 12 dB）。仅显示，不会改变声音。

逐条波形显示
右键点击“IN”、“SIDE”或“OUT”可调整平滑度（频率平均）和速率（5–60 Hz 刷新率）。这些设置纯粹是外观上的，它们会改变频谱的绘制方式，不会影响音频的处理方式。

Orra Ducker—–Per-frequency sidechain ducking
Most people use sidechain compression for ducking, which turns down your whole signal. Orra Ducker ducks only the frequencies that actually collide, keyed from any track, in any DAW. And with Orra Link, sidechain routing lives right in the plugin, so feeding several instances from different sources is the same simple workflow in every DAW.

Spectral, per-bin ducking across ~1000 frequency bins, not broadband
Draw the focus band, aim the duck at just the lows, the harsh mids, or the full range
Resolution control: carve surgically narrow or tilt broad and gentle
Stack multiple instances per track via Orra Link, 36 sidechain channels, keyed from any track in any DAW
Four latency modes: HQ, Balanced, Fast, and a zero-latency broadband Live mode for monitoring
One large analyzer shows input, sidechain, output, and the live ducking curve together
Self-key, host sidechain bus, or any Link channel, your choice per instance
Soft-edged focus band, stereo detector linking, and full automation on every control

Duck the collision, not the whole signal
Per-frequency, not per-fader.

Orra Ducker runs an FFT on both signals and ducks each frequency only where the two actually overlap, so a kick can clear space inside a bass without dropping the whole bass line.

The Usual Routing
Running several duckers on one track, each keyed from a different source, is doable in some DAWs but fiddly, and the setup is different in every single one. Aux tracks, bus juggling, send routing, and a fresh fight with your host every time you switch.

The Orra Way
Orra Link takes the routing off your plate. Source selection lives right in the plugin, and each instance just picks its trigger from a dropdown, up to 37 sidechain sources feeding one track. No aux tracks, no bus juggling, and the exact same workflow no matter what DAW you are in.

Orra Link is a tiny sender-only plugin that ships alongside Orra Ducker. It broadcasts a track’s audio onto a numbered channel in a shared bus that every Orra Flagship plugin in the project can read.

Drop it on any track or bus, pick a channel (Link 1 through Link 36), and that source becomes available as a trigger for any Orra Ducker instance in the project, even in hosts whose routing won’t normally let you sidechain across busses.

How It Works
Per-bin, not per-fader
A normal ducker measures one number from the sidechain, its overall level, and pulls down one fader. Orra Ducker runs a 2048-point FFT on both the trigger and your audio, splitting each into roughly a thousand frequency bins. Every bin gets its own detector and gain computer.

Only the bins that collide
A bin in your signal is ducked only when the matching bin in the sidechain crosses the threshold. That is why a kick can make space for itself inside a bass without dropping the whole bass line, only the bins the two share get touched.

Resolution is the carving tool
RESOLUTION sets how finely the per-bin reduction varies across frequency, surgical and narrow, or broad and smooth. It is the difference between a precise notch and a gentle tilt.

The Live exception
Live mode skips the FFT and runs a classic broadband envelope ducker, one detector, one gain, for zero-latency live monitoring. Every other mode is fully spectral.

Signal flow
Trigger source (None / External / Link) → per-bin detector → per-bin gain computer (Threshold, Ratio) → temporal smoothing (Attack, Release) → frequency smoothing (Resolution) → focus mask (Low / High Cut) → applied to your audio. Stereo detection is blended by the Link control before the gain computer.

The Analyzer
Four traces
Input (green fill), Sidechain trigger (gold line), Output (blue fill), and the live Ducking curve (red). The gap between input and output is the reduction, made visible.

Focus handles
Two gold handles set the low and high edges of the ducking range. Drag them directly or use the Low Cut and High Cut knobs. The region outside the band dims to show it passes through un-ducked. Dragging writes automation.

Reduction scale
The red ducking curve reads on its own ruler down the right edge, independent of the dBFS scale. Right-click DUCK to zoom it: 6, 9, 12, or 24 dB (12 dB default). Display only, never changes the sound.

Per-trace display
Right-click IN, SIDE, or OUT for Smooth (frequency averaging) and Rate (5–60 Hz refresh). Purely cosmetic, they change how the spectrum draws, never how the audio is processed.
