AVA Spectral Compressor

Product Introduction 产品介绍​

AVA Spectral Compressor
The AVA Spectral Compressor (AVA-SC) is a dynamics processor that allows you to apply compression selectively across 18 frequency bands.
These compression bands can either be spread out across the full range of the spectrum, or focused on a specific frequency range for more precise control.​

The AVA Spectral Compressor includes the following features:
Master Threshold control
Frequency Range selection
Band Depth controls
Gain Reduction graph
Compressor Knee
Output Trim​

Overview
The Depth sliders below the graph control the maximum amount of gain reduction that can be applied to the corresponding frequency bands determined by the current Range setting.
The Range can be set to focus on specific areas along the frequency spectrum (Low, Mid, High, etc.),
or it can be set to Full Range mode to allow control over the entire spectrum.
The Threshold sets the input signal level where the overall compression begins to take effect.
Additional controls include compressor Knee and output Trim.​

概述
图表下方的深度滑块控制对应频带可以应用的最大增益减少量，这取决于当前的范围设置。
范围可以设置为专注于频谱的特定区域（低音、中音、高音等），
也可以设置为全范围模式，以便对整个频谱进行控制。
阈值设置了整体压缩开始生效的输入信号水平。
其他控制包括压缩器 Knee 和输出修剪。

​

Controls
Threshold - The slider attached to the input meter on the left is the Threshold control.
The Threshold sets the input signal level where the overall compression begins to take effect.
The Threshold can be set anywhere between -60 and 0 dB.
Frequency Range - The Frequency Range section allows you to select the specific frequency range that gets processed by the compressor.
The 18 compressor bands will be distributed across whatever range is selected.
For example, with Mid selected, all 18 bands will be focused on the Mid-range, allowing for more precise control over the frequencies within that range.​

The available Frequency Range options are as follows:
Full Range - 16 Hz - 20 kHz
High - 3 kHz - 20 kHz
High Mid - 200 Hz - 18 kHz
Mid - 180 Hz - 7 kHz
Low Mid - 12 Hz - 8 kHz
Low - 15 Hz - 500 Hz​

Depth Controls
The 6 sliders below the graph set the Depth for their corresponding bands.
The 18 compressor bands are divided among the 6 sliders so that each slider controls the Depth for 3 of those bands.
The range of frequencies affected is shown below each slider.
Depth - The Depth determines the maximum amount of Gain Reduction that can be applied within each slider’s control range.
Possible Depth values range from -24 to 0 dB.
Setting a Depth slider to 0 dB will prevent any attenuation from occurring within that slider’s control range.​

Knee - The Knee value determines how far the input signal must exceed the threshold in a given band, to incur the full depth for that band.
Possible Knee values range from 1 to 30.
With a low Knee value (Hard Knee), the compression will activate more abruptly as the signal passes over the Threshold.
A high Knee value (Soft Knee) will apply the gain reduction more gradually as the signal passes the threshold.
Output Trim - The Output Trim adjusts the level of the compressor’s output signal anywhere from -10 dB to +10 dB.
It can be used to increase or decrease the output level as needed for gain compensation.​

Gain Reduction Graph
The Gain Reduction Graph provides a visual representation of Gain Reduction across the frequency spectrum.
The Reduction curve (red) is displayed above the Input curve (orange-yellow) indicating the amount of Gain Reduction applied and its location along the spectrum.
The red line inside the Input curve indicates the level of the compressed signal relative to the input signal.​

增益减少图表
增益减少图表提供了对频谱范围内增益减少的视觉表示。
减少曲线（红色）显示在输入曲线（橙黄色）之上，指示应用的增益减少量及其在频谱上的位置。
输入曲线内的红线指示压缩信号相对于输入信号的级别。

Additional Features
At the top-right corner of the plugin window are the Momentary Byass and Settings buttons.
Momentary Bypass - The Momentary Bypass button bypasses the plugin for as long as it's held.
This is useful for auditioning A/B comparisons quickly.
Settings - The Settings button reveals a pop-up menu where the window size and theme can be adjusted.
It also contains a link to the plugin manual and version info at the bottom.
Vintage Theme - The Vintage theme replicates the UI seen in Harrison’s large-format console software.​
