PROFESSIONAL, QUICK AND EASY RESULTS! O Spectral Compressor is an intelligent dynamics processor that was originally developed for film and post-production. It is derived from Harrison's iconic enterprise-class MPC consoles and provides unmatched precision when mastering.
It offers 18 spectral bands of dynamic range control, allowing you to sculpt the sound of each band individually or use the global controls to adjust the overall timbre of your mix. If you want to smooth out harsh frequencies, boost the bass, or brighten the highs, the Spectral Compressor can be excellent.
You can use it as an effective de-esser, a buss processor, or even a subtle enhancer for vocals and instruments. No matter what genre you work in, the Spectral Compressor will help you achieve a professional and refined sound.
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 band setting. 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 of the entire spectrum. Threshold sets the level of the input signal where overall compression begins to take effect. Additional controls include Knee compressor and output trim.

Controls
Threshold
The slider attached to the input meter on the left is the Threshold control. Threshold sets the level of the input signal where 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 will be processed by the compressor. The 18 compressor bands will be distributed across any selected track. 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
- Mid/High, 200 Hz – 18 kHz
- Mid, 180Hz – 7kHz
- Low/Mid, 12Hz – 8kHz
- Low, 15Hz – 500Hz
Depth controls
The 6 sliders below the graph set the depth for their corresponding bands. The compressor's 18 bands are divided between the 6 sliders so that each slider controls the depth of 3 of those bands.
The affected frequency range is shown below each slider.
Depth determines the maximum amount of Gain Reduction that can be applied within the control range of each slider. Possible depth values range from -24 to 0 dB. Setting a depth slider to 0 dB will prevent any attenuation from occurring within the control range of that slider.
knee
The Knee value determines how far the input signal must exceed the threshold in a given band to reach the full depth of that band. Possible Knee values range from 1 to 30. With a low Knee value (Hard Knee), compression will activate more abruptly as the signal passes above the Threshold. A high Knee value (Soft Knee) will apply gain reduction more gradually as the signal passes the Threshold.
Output Cut
Output Trim adjusts the compressor output signal level anywhere from -10 dB to +10 dB. Can be used to increase or decrease the output level as needed for gain compensation.
Gain Reduction Chart
Provides a visual representation of gain reduction across the entire frequency spectrum. The reduction curve (red) is displayed above the input curve (yellow-orange) 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.
