门限效果器 iFeature IFEA Spectral Gate v2.0.0 MacOS

MORiA | AU | VST3 | 8.9 MB

伊菲图音 —— 频谱门 选频门限效果器
阈值旋钮用于控制各类频率的通断与衰减幅度,借助快速傅里叶变换技术,该旋钮并非作用于整体信号,而是对每个频率仓独立生效。当某个频段的能量高于阈值时,该频段信号可正常通过;当能量低于阈值时,信号会被门限处理,即进行衰减或静音。这一设计能让你依据不同频率,精准把控信号的保留与剔除。
这款效果器的独特之处在哪?

传统门限效果器会根据整体音量作用于全部信号,而频谱门会捕捉频谱的每一个细微频段,并独立判定各频段信号的通断。

凭借这一特性,你可以实现:

・分离音频瞬态信号

・清除噪音或混响尾音

・以富有音乐性或更具冲击力的方式塑造音色质感

调低阈值,可打造粗粝且富有层次的音色效果;调高阈值,仅让声音中能量最突出的部分穿透呈现。
什么是阈值曲线?

阈值曲线功能支持你创建自定义阈值曲线,可自由添加任意数量的调节点。你能拖动单个调节点调整曲线形态,也可直接上下拖动整条阈值曲线,实现快速参数调节。

想要更高的调节精度?可切换至全屏模式查看详细频谱,以最大自由度精细调校曲线参数。
范围与平滑度分别是什么?

范围

用于设置被门限处理的频段信号回混至原信号的比例

・低范围数值 = 门限处理更严苛,更多频段被剔除

・高范围数值 = 更多被压制的基础信号被回混,营造更顺滑的音色质感

平滑度

用于设置频段信号跨越阈值时,门限效果的过渡缓急程度

・低平滑度数值 = 门限过渡更锐利,效果边界更清晰

・高平滑度数值 = 门限过渡更丝滑细腻,避免出现爆音,打造更具音乐性的朦胧效果

IFEA – Spectral Gate Frequency-Selective Gating.
The Threshold controls which frequencies pass through and which ones get muted or reduced, but instead of applying it to the whole signal, it works per frequency bin thanks to FFT. When the energy of a frequency band is above the threshold, it’s allowed to pass. When it’s below the threshold, it gets gated, meaning reduced or silenced. This gives you precise, frequency-dependent control over what stays and what goes.

Why it is special?
Unlike traditional gates that affect the full signal based on overall volume, the Spectral Gate listens to every tiny slice of the spectrum and decides what to let through.

That means you can
• Isolate transients
• Clean up noise or reverb tails
• Shape textures in a musical or aggressive way

Dial it low for a gritty, textured effect.
Dial it high to let only the strongest parts of the sound cut through.

What is Threshold Curve?
Threshold Curve lets you add a custom threshold curve with as many points as you want. You can drag individual points to shape the curve, or even drag the whole threshold up or down for quick adjustments.

Need more precision? Go full screen for a detailed view and fine-tune your curve with maximum control.

What are Range and Smoothing?
Range
Sets how much of the gated frequencies are blended back into the signal
• Low range = tighter gating, more frequencies removed
• High range = more of the floor/suppressed content mixed back in, creating smoother textures

Smoothing
Sets how gradually the gate transitions when frequencies cross the threshold
• Low smoothing = sharper, more defined gating
• High smoothing = glassy, polished transitions that avoid clicks and create more musical, washed-out effects

System Requirements
