这款经典的光学压缩器具有卓越的多功能性，其独特的起音和释放曲线使其与传统型号截然不同。

注意：此压缩器在 N3 中无法运行。这是我第一次制作出无法在 N3 中运行的压缩器。这是由于星云内部添加了一些函数造成的。

毫无疑问，这款压缩器是我所有压缩器中开发时间最长的。多年来，我多次尝试完善其设计，不断解决一些固有的功能性难题。

以下是各种模式的控制和说明：

比率：此控制项可修改压缩曲线，允许您调整信号的压缩程度。

阈值：此控制项设置信号被压缩的电平阈值。请注意，此控制项顺时针旋转——旋转它会增加受压缩影响的信号量。

输出：此控制项调整补偿增益，以补偿压缩造成的电平损失，确保输出平衡。

高通：此功能在压缩器的侧链中引入一个微妙的高通滤波器，通过减少低频成分的影响，实现更精准的压缩。

输入：此控制项专为音量极低的信号源设计，在阈值不足时提供额外的增益。但是，请注意不要使 Nebula 过载——仅在信号特别低时才增加此值。

模式：

固定模式：在此模式下，启动和释放控制项将被禁用，从而实现快速的启动和释放。与其他模式相比，这种速度可能会导致更大的失真，因为包络对信号变化的响应速度很快。

手动模式：此模式允许对时间常数进行精确调整。起音：起音控制非常灵敏；增加起音时间可以增强声音的冲击力和爆裂感。当接近最大值时，起音阶段会变得非常长，以至于会抑制压缩器的充能能力，从而导致压缩效果降低。

释放：该设备的突出特点是其独特的释放曲线，该曲线受压缩量的影响。与许多压缩器不同，释放持续时间会随着压缩量的增加而延长。这种设计可以最大限度地减少失真，并能应对更大的信号峰值。请注意，在释放旋钮设置较高时，释放时间可能会变得非常长。在释放旋钮上找到最佳释放时间取决于所施加的压缩量。

固定+手动模式：此模式结合了固定模式和手动模式的特点。在此设置下，手动模式下的起音控制旋钮会作为释放激活的可变充电量（起音时间越长，释放达到最大效果所需的时间就越长），这是一种两阶段释放。此操作类似于许多总线压缩器中的自动设置。固定模式的起音时间始终生效，如果手动模式下的释放没有被输入信号充分充电，则固定模式的释放将优先执行。手动模式的充电和接管能力取决于起音旋钮的设置。如果起音旋钮设置为最快，则释放几乎会立即开始压缩。如果起音旋钮设置为最慢，则在大部分瞬态过程中会使用固定释放，但乐器的延音在压缩状态下持续的时间越长，手动模式的充电量就越大。当起音和释放都接近最大值时，其行为类似于总线压缩器的自动模式，允许使用起音旋钮控制充电时间。要体验这种模式，请尝试使用更长的释放时间，并输入瞬态响应快、延音短的信号——例如小军鼓。调整 Attack 控制旋钮，从最快到最慢的设置开始，了解第二阶段是如何激活的。

This classic optical compressor offers exceptional versatility, featuring a unique attack and release shape that sets it apart from traditional models.

Note: This compressor will not work in N3. This is the first time I’ve ever made a compressor that will not work in N3. This is due to added Functions Inside nebula

This compressor has undoubtedly taken the longest to develop of all the compressors I’ve created. Over the years, I made several attempts to perfect its design, continually returning to address some inherent functional challenges.

Below are the controls and explanations of the various modes:

Ratio: This control modifies the compression curve, allowing you to adjust how aggressively the signal is compressed.

Threshold: This sets the level above which the signal will be compressed. Note that this control operates clockwise – turning it increases the amount of signal that will be affected by compression.

Output: This adjusts the makeup gain to compensate for any loss in level resulting from compression, ensuring a balanced output.

Hi Pass: This feature introduces a subtle high-pass filter into the sidechain of the compression, allowing for more focused compression by reducing the influence of low-frequency content.

Input: This control is designed for very low volume sources, providing additional gain if the threshold isn’t sufficient. However, be cautious not to overload the nebula – only increase this if your signal is particularly low.

MODES:

Fixed Mode: In this mode, attack and release controls are disabled, resulting in a fast attack and release. This speed can lead to increased distortion compared to other modes, as the envelope responds quickly to signal changes.

Manual Mode: This mode allows for precise adjustments to time constants. Attack: The attack control is highly expressive; increasing the attack time enhances the snap and crack of the sound. As you approach the maximum setting, the attack phase is so long that it dominates the compressors ability to charge, leading to less compression.

Release: A standout feature of this unit is its unique release shape, which is influenced by the compression amount. Unlike many compressors, the release duration lengthens as compression increases. This design minimizes distortion and holds for louder signal peaks. Be aware that the release can become very long at higher settings on the release dial. Finding the optimal release time on the release dial will vary based on the amount of compression applied.

Fixed+Manual Mode:This mode combines elements of both Fixed and Manual modes. In this setting, the attack control in Manual mode acts as a variable charge for the release activation (the longer the attack time, the more time it takes for the release to get to its maximum effectiveness), this is a two stage release. This operation is similar to the auto settings found in many bus compressors. Fixed mode’s attack time is always in effect, and if the release in Manual mode hasn’t been charged sufficiently by the input signal, the Fixed mode release will take precedence. Manual mode’s ability to charge and take over depends on the attack knobs setting. If the Attack is placed at its fastest setting it will charge its release into compression almost immediately. Attack placed at its slowest position will use fixed release for most of the transient, but the longer the sustain of the instrument is in compression, the more the manual mode will charge. When both attack and release are close to max, the behaviour resembles that of a bus compressor in auto mode, allowing for control over the charge time with the attack knob. To experiment with this mode, try using a longer release time and feeding a signal with fast transients and minimal sustain – like a snare drum. Adjust the Attack control to understand how the second stage activates, starting from the fastest to the slowest setting.
