TL Aggro provides the standard compression controls Threshold, Ration, Attack, Release, and Post Gain.
The Threshold control sets the amplitude level at which the compressor begins to affect the input signal. The values indicated on the Threshold knob are in negative dB. At the default 0 dB setting, TL Aggro will pass the audio signal through at unity gain and will have no effect on the audio. As the Threshold knob is turned clockwise (click and drag up), the threshold will be lowered deeper into the input signal and result in more gain reduction as the compressor becomes sensitive to more of the incoming audio signal.
The Ratio control indicates the degree at which TL Aggro is reducing dynamic range. The Ratio slider increases the amount of compression as the slider is pushed upwards, by increasing the amount of gain reduction in the output signal relative to the input signal. Additionally, as the ratio is increased, the “knee” of compression curve is made tighter. At lower ratio settings, TL Aggro has a gentle knee in the compression curve.
The Attack control controls the amount of time it takes TL Aggro to begin compression once the audio signal has reached the threshold. Slow attack times tend to promote overall brightness and high frequency audio within the compressed audio signal.
Conversely, the Release control controls the time it takes TL Aggro to return to unity gain once the audio signal has fallen back below the threshold. TL Aggro uses a program dependent release which slows down the release time to more smoothly ride the average loudness of the audio material.
Turning the Attack and Release knobs clockwise increases the reaction speed of the compressor. 1 is the slowest setting and 10 is the fastest setting.
The Post Gain control lets you make up for the signal gain lost through compression. The values indicated on the knob are in dB. At maximum setting, 36 dB of gain can be applied to the compressed signal.
