WHAT IS COMPRESSION?

Compression is the process of lessening the dynamic range between the loudest and quietest parts of an audio signal. This is done by boosting the quieter signals and attenuating the louder signals. The controls you are given to set up a compressor are usually:

  • Threshold - how loud the signal has to be before compression is applied.

  • Ratio - how much compression is applied. For example, if the compression ratio is set for 6:1, the input signal will have to cross the threshold by 6 dB for the output level to increase by 1dB.

  • Attack - how quickly the compressor starts to work.

  • Release - how soon after the signal dips below the threshold the compressor stops.

  • Knee - sets how the compressor reacts to signals once the threshold is passed. Hard Knee settings mean it clamps the signal straight away, and Soft Knee means the compression kicks in more gently as the signal goes further past the threshold.

  • Make-Up Gain - allows you to boost the compressed signal. as compression often attenuates the signal significantly.

  • Output - allows you to boost or attenuate the level of the signal output from the compressor.

What is Mixing? 

Audio mixing is the process of taking recorded tracks and blending them together. 

 

​Listen to each song a couple times and think about the questions below. 
 

What is the difference between the unmixed and mixed songs?  
What changes?
What can you hear clearly?

What can you hear in the front?
What can you hear in the back?

WHAT IS EQ?

Every sound is made of frequencies. Frequency is measured with Hertz (Hz). Equalizing is the art of boosting, cutting and balancing all the frequencies in a mix to get the sound you want.

You’ll often hear the frequency spectrum described as the Highs, Mids and Lows. Bass instruments have a very low-heavy, boomy sound. Their output is mostly low in the frequency spectrum. Alternately, a snare or a high-hat are a lot more tinny, so they will typically appear in the mid or high frequencies.

Even though we can place these sounds in the general high and low categories, all sounds will have important information in both the highs and the lows. Keep this in mind while you’re mixing.
