What is a compression effect? ​​The simplest analogy is to think of a compression effect as an automatic volume control. When your signal exceeds a certain rating, it will compress or attenuate the peak value of your signal. Basically It is to increase the weak audio signal and reduce the excessive audio signal. It will flatten the dynamic range of the signal to make the output more stable and flat.
What are the different functions of those adjustment knobs?
There is usually a volume or level control on the compression effect to control the output level of the effect. Another control button - usually labeled as sustainability, sensitivity or gain reduction (gain reduction) ) You can increase the compression range. In addition, you may also encounter the attack knob, which controls the cutting speed of the compression effect, allowing more transient signals to pass, thereby affecting the sustain of the note. There may also be a (tone) tone knob on the compression effect that can be used to control the brightness of the tone.
Do I need to compress the entire signal?
There is now a high-tech parallel compression effect that mixes the compressed signal with the original signal, so you can get some of the original signal dynamics while getting compression. Like Barber Tone Press and Wampler Ego effects can do this.
Another technique is multi-segment compression, so you can compress different frequency bands to different degrees. This function is very practical. For example, if you only want your low frequency signal to be tighter, then you can only have low frequency. The frequency band is compressed. However, this type of effect is rarely seen in pedal-type monoblock effects, but EBS has one such effect MultiComp.
How to use the compression effect to enhance the tone?
Compressed effects make your sounds tighter and smoother, smoothing the difference in volume between different notes and chords. If your plucking string is not stable, you can consider using a compression effect to balance To make the output more stable, especially suitable for playing chords or Funk music with a tight rhythm.
In addition, in some country music, there are often many fast-moving paragraphs, including many techniques for striking and hooking strings. If you add a compression effect, you can make each of your notes have the same volume. In other cases, the compression effect has another function, which can change the dynamic peak of the note, making the notes sound more grainy.
On the other hand, many people think that the biggest effect of compression is to increase the sustain. This long sustain is achieved under the unvoiced effect, not by using an overload or distortion effect. When your note volume is gradually decreasing. The compression effect boosts your level to keep it at a level for longer sustains, which is very useful for slider guitarists and longer for those who want to make the guitar unvoiced. People are also very helpful.
However, this is not to say that the compression effect can only be used on the modified unvoiced sound. The compression effect will work well with the speaker overload, and the compression effect can also be used as an incentive to make your speaker get more distortion.
